Abstract

The fill factor of perovskite solar cells is considerably lower than that of GaAs and silicon, though they have similar open-circuit voltage (Voc) deficits. To probe the fill factor loss, we applied the Jsc-Voc characterization technique on three different types of perovskite solar cells. Based on the Jsc-Voc measurements, we calculated the series resistance at maximum power point under different illumination - and thus injection - levels. We found that the series resistances of all three perovskite solar cells are illumination dependent, unlike silicon solar cells. Further analysis is underway to determine the origin of this phenomenon.
