  • The internal physics of a solar cell changes as it approaches the fundamental Shockley-Queisser limit. Photonic considerations overtake electronic ones, as an intense internal and external luminescence requires careful photon management. Counter-intuitively, maximizing light extraction increases voltage and therefore efficiency. Until 2010 the one-sun, single-junction efficiency record was set by a GaAs solar cell with an efficiency of 26.4% and an open-circuit voltage VOC= 1.03 V. Alta Devices… CONTINUE READING
