The outdoor power generation characteristics of a perovskite solar cell module with a nominal maximum output of 110W were measured over a period of one year to clarify seasonal variations in power generation characteristics and evaluate degradation. The module was installed facing south at a tilt angle of 35°, and various parameters of the solar cell were measured using IV curve tracing at four-minute intervals. As a result, a degradation of approximately 10% in conversion efficiency over one year was observed. The degradation was mainly due to a decrease in fill factor associated with a decrease in shunt resistance.
