Solar energy conversion describes technologies devoted to the transformation of solar energy to other (useful) forms of energy, including electricity, fuel, and heat.
The other avenue for improving the conversion yield of solar cells derives from the fact that these cells perform best under monochromatic light with a wavelength λopt (in nm) given by the following equation: where the band gap energy Eg is in eV and 1240 is a unit conversion factor (1 cm − 1 corresponds to 1.24 × 10 − 4 eV).
The conversion rate of solar radiation into electricity by PVs depends on cell type and is between 5% and 20%. Thus, the greater part of the absorbed solar radiation by PVs is converted into heat (at about 60–70%), increasing the temperature of cells.
Solar energy conversion has the potential to be a very cost-effective technology. It is cheaper as compared to non-conventional energy sources. The use of solar energy help to increase employment and development of the transportation & agriculture sector.
Just 20% of solar energy is converted into electricity; the remaining 80% is converted into heat (KatkarA et al., 2011).
