WebInAs quantum dots have been used to extend the absorption edge of InGaAs/GaAs quantum well solar cells from 940 to 1100 nm. In order to improve absorption of infrared radiation by the thin 300 nm active layer, we exploit its high refractive index, which acts as a waveguide for certain frequencies of light. WebJul 20, 2004 · The refractive index of GaAs, as measured by the prism refraction method, is reported here for photon energies from 0.7 eV up to the absorption limit set by the band gap, for temperatures of 300°, 187°, and 103°K.
