Notably, the decrease in Voc and PCE follows a linear trend, whereas Jsc and FF exhibit some variations at intermediate temperatures. Considering 25°C (298 K) as room temperature, the solar cell's output parameters are as follows: Voc = 0.97 V, Jsc = 35.22 mA/cm², FF = 86.42%, and PCE = 29.57%. This performance degradation with increasing temperature can be attributed to several factors. As the temperature rises, the bandgap of the semiconductor material decreases, leading to a reduction in Voc, which is a well-known characteristic of photovoltaic materials . Additionally, elevated temperatures result in higher carrier recombination rates, which negatively impact the charge collection process, leading to a decrease in Jsc and FF. Furthermore, the increase in temperature enhances intrinsic carrier concentration, which introduces additional thermal energy, causing higher resistive losses within the device and ultimately reducing PCE .
