Abstract :
In the paper results of investigating the characteristic features of temperature dependence of electrical parameters in dark I-V measurements for CdTe thin-film PV (photovoltaic) modules are presented. The purpose of originating the second junction in this kind of PV modules is shown. The electrical behaviour of II-(III)-VI thin-film PV cells/modules is influenced mainly by the defect layers located at the buffer/absorber interface and in the bulk of depletion region as well as due to manufacturing process. Results presented in this paper were determined from fitting the large amount of data acquired in natural outdoor conditions during long term monitoring [1].
