Abstract

III-V materials provide the highest efficiencies, but the higher cost of these materials compared to other alternatives such as silicon has limited their applications. One way of reducing the costs is by minimizing the amount of material needed. In this work, using optical simulations we test light trapping layers in the front and in the back of a GaAs single junction solar cell. By using these layers, we predict that we can obtain near optically thick GaAs single junctions with only 300 nm active material, with maximum calculated J_sc of 28.7 mA/cm² under the radiative limit.
