The effect of the recombination mechanisms location on the temperature sensitivity of thin-film photovoltaic cells
EDP Sciences / Research gate
Thin film solar cells temperature sensitivity and impact of the main recombination mechanism location are investigated in this paper. The main mechanisms in bulk and at the heterojunction interface are discriminated. Using a 1D simulation software, “Solar Cell Capacitance Simulator” (SCAPS), we observed a higher temperature coefficient of open circuit voltage (Voc) for cells with main recombination centers at the interface than the one with main recombination centers in volume. Furthermore, an LTSpice module model is used to visualize the effects of the recombination centers’ location on the performance ratios of the modules. The results show more degradation for the ratios performance of cells with the main recombination mechanisms at the interface than those in volume.
The weighted average cost of installed solar photovoltaicelectricity dropped from $5 /Watt in 2009 to about $2 /Watt in 2015 .
