Solar cells working at elevated temperatures generally exhibit inferior device performance than that characterized under standard test conditions due to increased internal carrier recombination. This work seeks to investigate the temperature coefficient of solar cells composed of crystalline and thin-film semiconductor materials, including Si, GaAs, CdTe, and perovskite under AM1.5G and AM0 irradiance spectra. The increasing temperature through continuous irradiance results in decreases of almost all the photovoltaic parameters, including short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF), and power conversion efficiency (η), with some exceptions for specific devices. The results in the cell underperforming overall as the temperature increases are used to determine the temperature coefficient of cell performance for each type of solar cell.
