Abstract

In this paper the modelling of the refractive index and reflectivity of a quantum well solar cell (QWSC) is theoretically developed and computationally analysed. The model is based on the Modified Single Effective Oscillator model combined with the Fresnel equation. The model takes into consideration the effects of the design parameters including concentration levels, structural properties of the device (well length, etc.), operating temperature and electric field effects (due to doping concentration). Prior to analysis the authors show the model to have a solid foundation given it generates accurate results which match with experimental data for an AlGaAs/GaAs triple heterojunction cell. This justifies and promotes further work where the theoretical and computational analysis is repeated for a QWSC structure. In the case of the QWSC the results generated are for a bare AlGaAs/GaAs cell and the same cell with a ZnS anti-reflection coating. The results generated show promise for the new model however experimental verification is required. The analysis is performed for AM 1.5G spectrum. The model is intended to be an aid to QWSC designers.
