Limiting efficiencies of GaAs solar cells [PDF]
IEEE Transactions on Electron Devices, 1990 The limiting efficiencies of GaAs solar cells when used under concentrated sunlight are calculated. The benefits to be expected from applying techniques which restrict the angle of acceptance of the cell are determined. It is concluded that when the acceptance angle is restricted the emission of the luminescent photons and therefore the associated ...
