This paper investigates, theoretically, the temperature dependence of the performance of solar cells in the temperature range 273–523 K. The solar cell performance is determined by its parameters, viz., short circuit current density ( Jsc ), open circuit voltage ( Voc ), fill factor (FF) and efficiency ( η ).
In a solar cell, the parameter most affected by an increase in temperature is the open-circuit voltage. The impact of increasing temperature is shown in the figure below. The effect of temperature on the IV characteristics of a solar cell. The open-circuit voltage decreases with temperature because of the temperature dependence of I 0.
The short-circuit current, I sc, increases slightly with temperature since the bandgap energy, E G, decreases and more photons have enough energy to create e-h pairs. However, this is a small effect, and the temperature dependence of the short-circuit current from a silicon solar cell is typically; or 0.06% per °C for silicon.
Besides, the temperature related studies will be important for further improvement in performance of these PV cells. This paper investigates the temperature dependence of the performance parameters of solar cells based on the following semiconductor materials: Ge, Si, GaAs, InP, CdTe and CdS in the temperature range 273–523 K.
Seasonal changes play a pivotal role in influencing solar cell temperature. During winter in cold climates, solar cells may encounter reduced efficiency due to the colder temperatures (Salamah et al., 2022). Cold weather can affect the performance of solar cells by altering the behavior of charge carriers and increasing resistive losses.
This section delves into the key elements influencing thermal effects on solar cells. External factors, such as climate, geographic location, and installation parameters, significantly impact the temperature of solar cells.
