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 form of an electron transport system to create their energy. In photosynthesis, during the light reaction phase, electrons are lost and replaced by splitting water molecules and the electrons are passed down an electron transport chain, releasing energy on the way. In solar cells, during the light absorption process, electrons are separated from the atoms and are transferred using metal...

...Plant Cell (Photosynthesis) versus Solar Cell Regina D. Parker October 31, 2010 Three ways a plant cell and solar cell are similar and different to each other is that plant cells and solar cells both convert sunlight into energy. In the case of plants it is chemical energy for solar cell; it is electricity. Plants use organic processes but solar cells use inorganic semiconductors.[i] Plant cells are different from the cells of most other organisms. Plant cells are usually larger than animal cells and surrounded by a rigid cell wall made from cellulose. They have a large central vacuole that takes up most of the cell and if they carry out photosynthesis, the plant cells will have chloroplasts. Plants have three types of tissues that are made up of different types of cells. Surface which is tissue forms the protective outer layer covering the plant, fundamental are only composed of one type of cell and are grouped based on the level of thickness of the cell wall, and vascular tissues are complex tissues that consist of more than one type of cell. Solar cells usually operate better under concentrated light. This has led to the development of a range of approaches using mirrors or lenses to focus light on to specially designed cells and use heat sinks, or active cooling of the cells, to dissipate the large amount of heat that is generated.  Unlike conventional flat plate PV arrays, concentrator systems require direct sunlight and will......

Photosynthesis and Semiconductor-Based Solar Cell

...SEMICONDUCTOR-BASED SOLAR CELL 1 Photosynthesis and Semiconductor-based Solar Cell Jorge Tavarez Strayer University PHOTOSYNTHESIS AND SEMICONDUCTOR-BASED SOLAR CELL 2 Abstract Energy is the capacity to do work and make things happen (Mader, 2009, p. 72). Human or other living things would not be on Earth without the source of energy. In photosynthesis, plant cells harness the sun’s solar energy with carbon dioxide to transform water molecules into oxygen, hydrogen and electrons and a semiconductor-based solar cell harnesses solar energy to convert it to electricity required by humans. In this paper, I will discuss the comparison and contrast of the two systems. I will also describe ways in which the plant cell and the solar cell are similar and different to each other. In addition, I will discuss how the laws of thermodynamics apply to each system. PHOTOSYNTHESIS AND SEMICONDUCTOR-BASED SOLAR CELL 3 Photosynthesis and Semiconductor-Based Solar Cell Two ways in which energy is created for the various life forms on earth are photosynthesis and the process that a semiconductor-based solar cell goes through to make energy. Photosynthesis is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism's activities. Semiconductor-based solar cells utilize photovoltaic (PV) panels to......

Photosynthesis

...The plant photosynthesis process and semiconductor-based solar cells processes are very similar in their functions and creating an end product as well as there are a variety of differences between them. First we need to look at photosynthesis, which is the process by which plants, algaes and cyanobacteria absorb sun light and convert it to sugar. In the photosynthesis processes, the plant absorbs the sun light then in complex processes converts the intake of carbon dioxide to the end results to sugar (carbohydrates) and releases water and oxygen. The oxygen is what humans and all living animals use to survive and breathe in. Humans and animals release the carbon dioxide which is what the plants absorb in with as well as the light rays from the sun. According to Mader, “if the amount of carbohydrate were instantly converted to coal, and the coal loaded into standard railroad cars (each car holding about 50 tons), the photosynthesizers of the biosphere would fill more than 100 cars per second with coal” (2010, p.86). During my research on semiconductor-based solar cell energy, I found that the solar cell energy is capture in about the same means that the plants absorb light rays and carbon dioxide. The solar cells are made up of usually silicone. In 2010, Heindl stated, “the second most abundant element in earth`s crust, silicon has the advantage, of being available in sufficient quantities, and additionally processing the material does not burden the environment” (e.g.,......

Plant Cells vs Solar Cells

...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. (Oppapers.com). 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 (Oppapers.com). 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...

Solar Power as Away of Providing Heat and Electrical Energy from Heat

...Solar power as away of providing heat and electrical energy from heat The Sun the heat of the sun is about equivalent to burning a billion trillion tons of coal an hour. Even though only a small fraction of that heat ever reaches the earth it is still more then enough to power the whole world. People seemed to realize the importance of the sun around 30,000 BC. This was when people first started planting crops of wheat. They realized plants did better when planted in the sun over the shade. This caused them to worship the sun as a God. Many cultures built large and extravagant temples to worship the sun in. Other cultures built places to observe the sun in, such as Stonehenge in England. Different Types of Solar Panels There are three main types of solar panels. They are flat plate collectors, focusing collectors, and solar cells. The first kind is a flat plate collector. Flat plate collectors are fastened on the top of the roof of a house. They usually either heat the house or its water. A flat plate collector consists of a black rectangular frame, two or three sheets of glass, and copper plumbing. A flat plat collector uses the greenhouse affect. The sun rays go through the glass but can’t get out through the glass. The sun rays heat the water-filled copper tubes. Then the water is used to heat the home or water. Another type of a solar panel is a focusing collector. They consist of a mirror or......
