What is solar energy conversion?

Solar energy conversion describes technologies devoted to the transformation of solar energy to other (useful) forms of energy, including electricity, fuel, and heat.

How can we improve the conversion yield of solar cells?

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).

What is the conversion rate of solar radiation into electricity?

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.
