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 plants make their food thanks to the fact that they have chlorophyll. Chlorophyll is the pigment that creates the green color in plants and it "…captures the Sun's energy and uses it to make sugars out of carbon dioxide from the air and water" (Ohio State University, 2008). The sugars are vital to the process because they provide fuel for the roots of the plant, the stems and leaves of the plant, and allow the plant to continue to grow. And once the plant has made adequate food through sunlight to provide a healthy condition for the plant, it releases oxygen into the air, and of course oxygen is what humans and animals need in order to breathe and live.
In the Handbook of Photovoltaic Science and Engineering, the...
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

solar flares and how they go on to cause global warming. Global warming has been an ongoing phenomenon and there are many reasons it has occurred. Apart from the green house effect, global warming could have been due to the solar flares that have occurred. Different researches and theories regarding this matter are discussed in the paper. Solar Flare Global warming is a phenomenon that has amazed and frightened everyone ever
Around 21 billion of co2 is launched into the environment annually which is too much for the environment of Earth to neutralise or utilise normally. The manufacturing of co2 from burning non-renewable fuel sources is among the most considerably important contributing greenhouse gases. The boost of greenhouse gases in the environment is developing a substantial increase in worldwide temperature level which is a direct link in between non-renewable fuel
Photovoltaic power system is a type of renewable energy that converts solar energy into solar photovoltaic electricity. Photovoltaic (PV) technology converts energy from the sunlight into the electricity. One of the advantages of the PV technology is that it is pollution free, and it is applicable with little maintenance. (EPIA 2008). Since sunlight is available free of charge, there has been an increase in the research and development (R&D) to make
