Low-temperature-deposited silicon nitride and aluminum oxide films are investigated for reducing carrier recombination at the silicon surface. The insulator/silicon interface properties (fixed charge density, fast interface state density, and surface recombination velocity) are studied as a function of deposition and annealing temperature in the range of 270/sup 0/ - 550/sup 0/C. The effects of UV irradiation and their elimination by charge-induced passivation are extensively discussed. The successful application of both films for front surface passivation of a novel thin-silicon solar cell of the back collection type (BACK-MIS cell) is demonstrated. Finally, a simple configuration for efficient back surface passivation of solar cells is introduced as a possible substitute for the conventional back surface field.
