Semi-conductor based solar cells and Photosynthesis has many qualities that are in common. Plants receive sunlight from contact (light reaction). A photovoltaic (PV) panel provides sunlight to the solar cells. Similar to how sunlight helps produce chlorophyll in plants, semiconducting material absorbs sunlight. (
Because of their outputs, photosynthesis and semi-conductor solar cells have great value.. In order to create food, plants absorb sunlight and create oxygen. While this process takes place, plants use sunlight and carbon dioxide to convert water molecules into hydrogen, oxygen, and electrons (
The light reaction of photosynthesis can be easily compared to how electricity is created with solar cells. The electrons that are in the solar cell get energy from the sun; from that point they are converted to a high energy level. After being turned into a high energy level, they are then accepted by the wire to run the semi-conductor motor. These processes are similar because they both lose electrons. In solar cells electrons are replenished when the electrical circuit is complete and in plant cells, splitting water furnishes more electrons (Johnson, S.).
Although they have similarities, they are also very different. Plants have a more difficult time at absorbing sunlight than solar cells. Plants have the responsibility of providing energy to live on, whereas solar cells only have to provide electricity for a wire. It is very important that process of photosynthesis is not done in error, if something goes wrong it may kill the organism. One key aspect is that solar cells rely solely on sunlight (Miller, S.).
Photosynthesis, on the other hand, requires water and carbon dioxide absorption through stomata as well as sunlight. The other central difference is the end product; although both count as “energy,” photosynthesis relates less to the flow of electrons and more to the breaking and combination of chemical compounds (Miller, S.).
Universal laws of energy exchange, the laws of thermodynamics, govern all interactions among organisms (and all matter) (
The first Law of Thermodynamics states that energy is something that happens naturally it cannot be produced or demolished. It comes in two forms one of them being energy on reserve to perform activity and the energy that is being used at the time. These energies are called potential energy and kinetic energy (
The second Law of Thermodynamics—the law of entropy (disorder) basically states that products of a reaction that uses energy is not going to be as potent as the original. (
In each energy exchange, it is guaranteed that energy will reduce from loosing heat. Based on the law of conservation, energy is still there it’s just lost most of its “power” and is unable to assist in metabolism. (

Comparing Photosynthesis and Semiconductor Based Solar Cells

...many similarities and also many differences when comparing photosynthesis and semiconductor based solar cells this paper will outline those these as well as give a description of the two cycles. I will also be defining the law of thermodynamics and explaining how it applies to photosynthesis and also semiconductor based solar cells harnessing solar energy. Photosynthesis is the process of converting solar energy into chemical energy in the form of carbohydrates. For photosynthesis to occur a few factors must be present such as water, carbon dioxide, chlorophyll, and light energy. Photosynthesis consists of two sets of reactions the first being the photo portion or light reaction which is the reaction that captures solar energy the second being the synthesis reaction or Calvin cycle reactions which converts that solar energy into carbohydrates (Mader, 2010). For light reactions to occur first light energy enters the cells and is absorbed by the chlorophyll. That Light energy raises the energy level chlorophyll enabling electrons to be freed form the chlorophyll molecules. This makes the chlorophyll molecules positively charged the electrons from hydrogen atoms are attracted to the positively chlorophyll causing water molecules to break apart into oxygen atoms. The elections freed from the chlorophyll and the protons freed from water take part in the chemical reactions in the cell. The reactions result in the production of adenosine triphosphate (ATP) and nicotinamide......

...Solar and Plant Cells Compared Tiffany L. Triggs Strayer University The Importance of Energy For plant Earth, the Sun is the main source for all energy. It is the main essential thing that provides us with light, warmth and energy. Some organisms, such as plants and algae, create their own food using the sun as their main source of energy. In turn the fuel the rest of the world by creating energy for animals and humans after being consumed. They also remove carbon dioxide from the air and replenish oxygen for us to breath. This process, through which this energy is harnessed and used to create food, or carbohydrates, is called photosynthesis. Can the energy of the sun be harnessed by humans to create energy? It can be and it is through the use of solar cells. Photosynthesis and solar cells are similar, yet different in a few ways. Creating Our Own Energy Humans have figured out how to use the power of the sun for energy. Using Solar panels containing semiconductors, we can turn the sun into electricity, a very popular form of energy. In this way, photosynthesis and solar cells are similar, both using the suns light to create a form of energy. The type of energy created, however, is where one difference comes into play. Plants create a chemical energy known as carbohydrates, a simple organic compound of oxygen, carbon and hydrogen, while solar cells use semiconductors to produce electricity. Use of Electrons Solar Cells and Photosynthesis both use a......

Animal and Plant Cells Lab Report

...Lori Stenbeck Bio K121 June 14, 2012 Animal and Plant Cells Introduction: There are two different types of cells, prokaryotic and eukaryotic. Prokaryotic, such as bacteria, lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotic, such as plant and animal cells have a nuclear membrane and other membrane bound organelles. Their genetic structure consists of one or more linear strands of DNA. Eukaryotic cells have a nucleus, cytoplasm, and a plasma membrane surrounding the cell. The typical plant cell has in addition a cell wall, a rigid structure made up of cellulose that surrounds the plasma membrane. Most animal cells are mostly filled with cytoplasm, whereas the plant cell has much of its volume taken up by a central vacuole containing water, salts, sugars and other compounds. The purpose of this experiment is to differentiate between prokaryotic and eukaryotic cells. Also to distinguish among plant and animal cells and identifying the organelles that are evident in them. Eukaryotic Cells: Plant Cells: Elodea: When viewing the Elodea (also known as pond weed) it was easy to distinguish it was a plant cell due to its rectangular shape. The cellular organelles that were observed were a cell, wall, chloroplast, cytoplasm, and a nucleus. The nucleus was located off to the side of the cell. This was assumed to be because of the large central vacuole. As the slide began......

...Objective In this experiment, the performance of solar cells under different working conditions are investigated. These variables include light intensity and temperature. This is achieved by studying the different current-voltage characteristic curves. Also, the relationship between short-circuit current and no-load voltage with different working conditions is studied. Introduction Solar Cell A solar cell (or a "photovoltaic" cell, Fig. 1) is a semiconductor device that converts light energy in the form of photons from the sun (solar light) into electricity. Solar cells have many applications and are regarded as one of the key technologies towards a sustainable clean energy supply. [pic] Fig. 1 A solar cell, made from a monocrystalline silicon wafer Silicon solar cell has a structure of a pn junction. Silicon can be doped with tri- and pentavalent atoms to make a p- or n-type semi-conductor. If we put a p-and n-type crystal together we get a junction (pn-junction, Fig. 2) whose electrical properties determine the performance of the solar cell.

H. Karam Spectrolab, Inc., 12500 Gladstone Ave, Sylmar, CA 91342, USA ABSTRACT Multijunction III-V concentrator cells of several different types have demonstrated solar conversion efficiency over 40% since 2006, and represent the only third-generation photovoltaic technology to enter commercial power generation markets so far. The next stage of solar cell efficiency improvement, from 40% to 50%-efficient production cells, is perhaps the most important yet, since it is in this range that concentrator photovoltaic (CPV) systems can become the lowest cost option for solar electricity, competing with conventional power generation without government subsidies. The impact of 40% and 50% cell efficiency on cost-effective geographic regions for CPV systems is calculated in the continental US, Europe, and North Africa. We take a systematic look at a progression of multijunction cell architectures that will take us up to 50% efficiency, using modeling grounded in well-characterized solar cell materials systems of today’s 40% cells, discussing the theoretical, materials science, and manufacturing considerations for the most promising approaches. The effects of varying solar spectrum and current balance on energy production in 4-junction, 5-junction, and 6-junction terrestrial concentrator cells......

Solar Cell vs. Wind Turbine solve the issue, people must cut short electricity use and increase power input. It means that devices should be off when they are not in use, replace obsolete bulbs with energy efficient bulbs and at the same time build more energy harvest systems to enhance electricity production. Electrical energy can be produced by renewable sources and non-renewable sources of energy. With development in the technological field, renewable resources like water, solar, and wind current are preferred to produce electricity in order to replace fossil fuel which would not last very long. In fact, natural resources can produce multi-folds of electricity without being eradicated. However, this essay is comparing solar panel to wind turbine. Their major differences are location, method and efficiency. Initially, the difference of both solar panel and wind turbine is method of generating electricity. Since the solar panel has defined as an object that absorbed the sunlight and turns it into electricity. The method to generate electricity by solar panel is complex. Firstly, after the sunlight shines into the panel, it has been converted from protons to electrons (Llorens, n.d.). After that, the current’s output is in a form of direct current. This is a type of electrical current which flows in one direction in a circuit and mostly loss energy when energy is carried over a long distance (“Alternating Current,”n.d.). However, the current of electricity that people use in the houses, for......

Plant Cell vs Solar Cell

...Plant Cell versus Solar Cell Katrina Minchew July 18, 2011 Strayer University | | Photosynthesis is defined as the process in which green plants and other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. It takes place mainly inside the leaves. This process utilizes light energy and it is transformed into chemical energy used to create organic compounds. Photosynthesis consists of two processes that use both light and dark energy. The first process, light reaction transforms light into energy. The second process utilizes dark reactions, use the energy and carbon dioxide to produce sugar. The process needs sunlight, water, and carbon dioxide. These materials are transported through the leaves. Water is absorbed by the plant through the roots and is then delivered to the leaves through the plant tissue. The carbon dioxide is absorbed through small holes in plant leaves known as stomata. It also releases oxygen. The process known as chlorophyll is when the green pigment of plants and photosynthetic algae and bacteria trap the energy of sunlight. In plants, photosynthesis takes place inside the chloroplasts, which is the organelle that carries out photosynthesis and starch grain formation. A chlorophyll-containing organelle in plants is the site of photosynthesis. A solar cell also known as the photovoltaic cell is a solid state electrical mechanism that converts the energy of light directly into......

Semiconductor Based Solar Cell Biology – SCI 115 23 January 2012 Abstract This paper discusses photosynthesis and how it is used by plants to harness solar energy. It also discusses semiconductor-based solar cells and how they are able to harness solar energy and convert it to electricity. This paper also compares the two types of solar energy systems and provides an overview of how the two systems are alike and how they are different. In closing, this paper will briefly explain how the laws of thermodynamics apply to each of the two energy systems. Photosynthesis Photosynthesis is a process that transfers solar energy, or energy from the sun, into a chemical energy that provides nutrients to plants and animals all over the world. Without these important nutrients, plants, animals and humans would not be able to survive on earth. “Animals and plants get energy by metabolizing nutrient molecules made by photosynthesizers.” (Mader, 2010) Semiconductor-Based Solar Cell Before discussing what a semiconductor-based solar cell is, I would first like to define a semiconductor and then explain how it is used in a solar cell type environment.

Photosynthesis vs Semiconductor Based Solar Cell

...semiconductor-base solar cells they have many similarities as well as differences. In this paper I will explain to you exactly what they are. I will also point out how the laws of thermodynamics apply to both processes. One major similarity between photosynthesis and semiconductor-based solar cells is that they both require solar energy or sunlight for the process to begin. Photosynthesis’ main function is to transform solar energy into the chemical energy of a carbohydrate (McGraw-Hill Learning Solutions, 2009 p. 86). Energy from the sun is absorbed by chlorophyll, which is a pigment in the chloroplasts (membrane bound organelle in algae and plants with chlorophyll, where photosynthesis takes place) of plants. Once in the chloroplasts the energy is used to split water into hydrogen and oxygen. The hydrogen then combines with carbon dioxide to make sugars and energy-storing compounds. A solar cell is a device that converts solar energy into light at the atomic level. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material (NASA Science). Another thing that they have in common is that man kind also relies on both processes for survival. During photosynthesis food and oxygen are produced, and carbon dioxide is removed from the air and without solar energy we wouldn’t have electricity. Another similarity is that during the process they both lose electrons. When the electrons are lost in solar cells they are......
