Abstract
Conference Title: 2017 IEEE 44th Photovoltaic Specialists Conference (PVSC) Conference Start Date: 2017, June 25 Conference End Date: 2017, June 30 Conference Location: Washington, DC In this work, we investigate the temperature and irradiance dependencies of the power output of silicon solar cell architectures (BSF, PERC, PERT, SHJ). When we compare our data with commercial module datasheets, we find that the temperature coefficient under maximum power point conditions is systematically worse in the modules. Following our analysis we attribute this to ohmic losses $(R_{\mathrm{CTM}})$ due to cell interconnection. Using energy yield calculations we show the impact of $R_{\mathrm{CTM} }$ on the energy production in moderate and hot and sunny climates for all investigated architectures. We conclude that maximizing energy production in hot and sunny environments requires not only a high open-circuit voltage, but also a minimal series-to-Ioad-resistance ratio.
