Title: Open-circuit voltage, fill factor, and efficiency of a CdS/CdTe solar cell

Abstract

The dependences of the open-circuit voltage, fill factor, and efficiency of the thin-film CdS/CdTe solar cell on the resistivity {rho} and carrier lifetime {tau} in the absorbing CdTe layer were studied. In the common case in which the uncompensated acceptor concentration and the electron lifetime in the CdTe layer are within 10{sup 15}-10{sup 16} cm{sup -3} and 10{sup -10}-10{sup -9} s, the calculation results correspond to the achieved efficiency of the best thin-film CdS/CdTe solar cells. It was shown that, by decreasing {rho} and increasing {tau} in the absorbing CdTe layer, the open-circuit voltage, fill factor, and efficiency can be substantially increased, with their values approaching the theoretical limit for such devices.
