Abstract


Understanding the output characteristics of various devices under various field conditions is necessary. However, maximum power point tracking (MPPT) algorithms for devices with extremely slow responses are complicated, and the electronic response during MPPT differs with temperature and device freshness. In this study, the field performance of perovskite solar cells loaded with fixed resistors was monitored for one year. The daily efficiency, calculated by dividing the daily energy delivered to the solar cells by the diurnal irradiance energy incident on the device, exhibited seasonal variations. the efficiency increased with increasing temperature, showing a positive coefficient, which aligned with the observed seasonal variation in the efficiency. Furthermore, temperature correction of the efficiency revealed efficiency loss patterns, such as an initial burn-like decay and degradation, which followed after a period of constant efficiency.
