Further improvement of the open-circuit voltage (V oc ) of thin-film photovoltaic devices requires that the rate of non-radiative recombination be monitored and reduced. In this study, we investigate a method that attempts to account for the excitation and temperature dependence of V oc and photoluminescence (PL), to extract detailed information about the spatial distribution of recombination and the effects of back contact offset.
