Energy Conversion Labs are fundamentally transforming how we harness and utilize energy. Through innovative research from institutions like MIT and Columbia University, they convert traditional and renewable energy forms—such as fossil fuels, solar, wind, hydro, and biomass—into usable power while incorporating advanced energy storage solutions.
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 describes technologies devoted to the transformation of solar energy to other (useful) forms of energy, including electricity, fuel, and heat.

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.
Because the light used in PV applications contains many different wavelengths, many different generation rates must be taken into account when designing a solar cell. The generation rate gives the number of electrons generated at each point in the device due to the absorption of photons. Generation is an important parameter in solar cell operation.
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).
