Abstract

This paper proposes a comparative study between two sub-micrometric multi-layered photovoltaic cells, based on A_II–B_VI compounds, using different structures for the holes transport and collection electrode. Using the modified form of the Shockley equation, the diode factor, n, the reverse saturation current, I₀, and the series R_s and shunt R_sh resistances were evaluated and their effect on the photovoltaic cells performances were discussed. The photovoltaic performances were analysed by current-voltage characteristics at illumination in standard AM 1.5 conditions, and the specific parameters were determined.
