The thickness dependences of the photocurrent quantum yield and photoenergyparameters of silicon backside contact solar cells (BC SC) are investigatedtheoretically and experimentally. The surface recombination rate on theirradiated surface was minimized by means of creating the layers of microporoussilicon. A method of finding the surface recombination rate and the diffusionlength of minority carriers from the thickness dependences of the photocurrentquantum yield under conditions of the strong absorption is proposed. Theperformed studies allowed us to establish that the thinning of the BC SCsamples in the case of minimizing the surface recombination rate gives apossibility to achieve rather high efficiencies of photoconversion. It is alsoshown that the agreement between the experimental and theoretical spectraldependences of the photocurrent quantum yield can be reached only with regardfor the coefficient of light reflection from the backside surface.
