The solar PV combined with a thermal system can be used to reduce cell temperature. Rostami et al. 44 used CuO nanofluid in a PVT system to increase the efficiency and cooling performance of a PV module. The researchers reported that the average surface temperature drops up to 57.25%, and maximum power reaches 51.1% compared to no cooling system.
Solar cells are much more environmental friendly than the major energy sources we use currently. World’s market for solar cells grew 62% in 2007 (50% in 2006). Revenue reached $17.2 billion. A 26% growth predicted for 2009 despite of recession. Sun powered by nuclear fusion. Surface temperature~5800 K Will last another 5 billion years!
In line with these innovations, there are concerns about greenhouse gas emissions of the solar cells, materials for the solar technologies and other relevant environmental impacts of the manufacturing processes. This review is conducted on life cycle assessments of solar cells, considering the climate change and natural resource shortage context.
It is identified that the majority of existing life cycle assessments on solar cells take into account four typical environmental impacts: energy consumption, greenhouse gas emissions, material depletion, and toxicity.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
Solar cell is the backbone of solar energy technologies, which converts solar radiation into power.
