OPTIMUM BASETHICKNESS DETERMINATION OF A BACKILLUMINATED SILICON SOLAR CELL: IRRADIATION EFFECT

In this paper, we propose a method to determine the optimum thickness of a bifacial silicon solar cell back illuminated and under irradiation. The expressions of back surface recombination velocity of excess minority carrier depending on both irradiation energy (ϕp) and damage coefficient (kl) are established. From their plots, base optimum thickness is deduced, and its relationships with bothirradiation energy (ϕp) and damage coefficient (kl) are modeled.
