Thermal effects in the context of solar cells refer to the changes in their electrical and optical properties due to variations in temperature. As solar cells operate, they invariably generate heat.
In steady weather conditions, the thermal response time of a solar cell with a Si thickness of 100-500 μm is around 50-250 s. While in realistic scenarios, the panel temp. variation in a day is different from that in steady weather conditions due to the effect of thermal hysteresis.
By way of illustration, a recent article reports on the design of solar cells for operating at high temperature in the lower atmosphere and at the surface of Venus where the temperature can reach 465°C. Photovoltaic operation in the lower atmosphere and at the surface of Venus. Prog. Photovolt. Res. Appl.2020; : 545-553
With an increase of ambient temp., the temp. rise of solar cells is reduced. The characteristics of panel temp. in realistic scenarios were analyzed. In steady weather conditions, the thermal response time of a solar cell with a Si thickness of 100-500 μm is around 50-250 s.
Solar cell performance decreases with increasing temperature, fundamentally owing to increased internal carrier recombination rates, caused by increased carrier concentrations. The operating temperature plays a key role in the photovoltaic conversion process.
In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.
