Photosynthesis is the process by the help of which plants make their own food by capturing the solar energy. Solar cell as compared to the plants coverts the sunlight into electric energy in order to be used by the human beings. This paper aims to highlight the differences and similarities between a plant cell and a solar cell in addition to the application of laws of thermodynamics to each system.
Laws of Thermodynamics
In the case of photosynthesis and the solar cells, three laws of thermodynamics are applicable. According to the first law of thermodynamics, energy, or mass cannot be created nor they can be destroyed (Rana, 2008, p. 67). The first law of thermodynamics is fulfilled by the plant cells as no new energy or mass is being created but solar energy is being converted into chemical energy or electric energy in the case of solar cells. Second law says that not all of the energy absorbed from the reservoir can be converted...
However, unlike chlorophyll, silicon cannot be used for energy-generation in its raw state, and must be processed by humans. Silicon is favored "because it remains a good conductor of electricity even after it has been heated. In order for silicon to be used for solar cells, it must be heavily heated to separate it from oxygen so that it can be further processed" (Stier 2009). Although solar energy is
Photosynthesis & Solar Photovoltaic Technology What is photosynthesis and how does photosynthesis work? How is process of photosynthesis linked to photovoltaic technologies? How are they the same and how are they different? This paper will delve into those issues and provide answers to the questions. Photosynthesis is the process in which green plants create their own food thanks to sunlight shining on them. Animals eat other organisms for their nutrient intake, but
Photosynthesis and the Laws of Thermodynamics Photosynthesis is the systematic process used by plants as a means to harness solar energy. A semiconductor-based solar cell harnesses solar energy to convert it to electricity required by and used by humans. As such, the process of photosynthesis is a contributor to both plant and solar cells. There are numerous similarities and differences between plant and solar cells; however, they both ultimately work to
Photosynthesis 1231 Plant Cell and Solar Cell: Similarities and Differences Photosynthesis is that process by which plants harness the solar energy for producing food. These cells help the plants to trap energy from the daylight. This trapped light is converted into other constituents that are then used by the plant to manufacture food. The additional components such as oxygen are released to the atmosphere. After these processes, the light energy is converted
Harness of Solar Energy Harnessing of Solar Energy Relation of photosynthesis and the semi-conductor-based solar cell Harnessing of Solar Energy Both photosynthesis and the semi-conductor solar cells are important in regards to the human lifestyle. Photosynthesis helps in the manufacture of carbohydrates that are used for food by humans. Semi-conductor-based solar cells provide energy in the form of electricity that is also consumed by humans. Photosynthesis Photosynthesis in its broader definition is a process that entails
ecosystem" is used frequently in the popular media, and yet most people do not have a clear, working definition of an ecosystem. An ecosystem simply refers to all of the organisms and their physical environment that exist within a certain, specific area. This includes all plants, animals, and their environment, which can include water, dirt, rocks, and the air that surrounds them. For example, all of the organisms that
