How Radiation and Energy Distribution Work in Solar PV
Solar constant and solar spectral irradiance describe solar radiation. The solar constant is the amount of total radiant energy received from the sun per unit time, per unit area exposed normal to the sun''s rays, at the mean sun-earth distance at the outer layer of the earth''s atmosphere.
Spectral Response
Any energy above the band gap energy is not utilized by the solar cell and instead goes to heating the solar cell. The inability to fully utilize the incident energy at high energies, and the inability to absorb low energies of light represents a significant power loss in solar cells consisting of a single p-n junction.
