Paper Abstract

Solar cells based on ITO-InP are currently being studied extensively for application to space satellite power systems. The enthusiam for the ITO-InP cell results fromtheir low degradation under exposure to radiation typical of space environments. It is believed that the performance of the cell is profoundly influenced by the precise nature of the various layers and interfaces involved. A simple numerical model has been developed for prediction of performance of the ITO-InP cell. The iterative routine developed to date is based on the Transmission Line Matrix (TLM) method of numerical analysis. This method has the advantages of being physical in its concepts, one-step, explicit, and unconditionally stable. The model deals with the creation, diffusion and recombination of excess carriers on both sides of the junction, together with separationof carriers in and near the junction region. The ultimate aim of the model is to predict the optimum precise cell structure. Here the model has been used to predict the short circuit output of a cell in reponce to incident light of various spectral compositions. The results of the simulations are compared with experimentally derived values.
