Analysis of heat and photon recombination losses in solar cells

Photoconversion efficiency of light into electrical current is limited by recombination, thermal and other losses of photon energy in the structures of solar cells, including those used in space vehicles. The equations describing the loss, adjusted the light dispersal ohmic losses in the surface layer. For the first time an assessment of the heat losses due to Peltier effect at the contacts of the circuit of solar cells. The ways to minimize recombination losses in the surface layer due to the electric field of contact charges are discussed.
