Abstract:In this paper, we present a two-dimensional polycrystalline solar cell model to determine the parameters of the cell, such as the photocurrent, the dark current and the conversion efficiency. In this model, we consider an exponential doping profile of the p-region of the cell and hence the onset of an electric field in this region in order to reduce the minority carrier recombination at grain boundary and at rear contact. Consequently, this improved conversion efficiency of the cell. In order to optimize conve… Show more
