Abstract :
Conventional solar cells collect photons from the solar radiation in p-n junctions. Their efficiency is constrained by the Shockley-Queisser limit, due to blackbody radiation, spectral loss, excessive energy of the absorbed photons, and recombination loss. As of August 2013, the highest efficiency achieved by a single-junction solar cell, made of GaAs, is 28.8 %.
