Abstract

We use recorded weather data as input parameters for device simulation to compare different types of solar cell concepts under realistic conditions. Recorded data shows that commonly used standard test conditions are not very representative for the chosen location in central Europe. We use 2D-models of Al-BSF, PERC and POLO-IBC cells to simulate the behavior of the cells under varying temperature and irradiance. With the recorded weather data for a whole year, we can estimate the cell performance in field at the given location. The simulations show that all three cell types seldom reach their STC performance under realistic conditions (for the given degree of latitude). The comparatively low irradiance of the investigated location highly impacts the operation of the IBC cells. For irradiances below ~200 W/m² we find a drastically decreased fill factor due to an increase in Shockley-Read-Hall recombination. Nevertheless, IBC shows vastly superior performance over Al-BSF and PERC, overall, and especially under high irradiance.
