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.
So, the estimated PV cell temperature under these conditions is 56.25°C. Enter the ambient temperature and actual solar irradiance to estimate the PV cell temperature: Ambient Temperature (°C): Actual Solar Irradiance (W/m²):
Most semiconductor modeling is done at 300 K since it is close to room temperature and a convenient number. However, solar cells are typically measured almost 2 degrees lower at 25 °C (298.15 K). In most cases, the difference is insignificant (only 4 mV of V oc), and both are referred to as room temperature.
The actual value of the temperature coefficient, in particular, depends not only on the PV material but on T ref , as well. It is given by the ratio 1 ref oref TT (4) in which T o is the (high) temperature at , Garg and Agarwal . For crystalline silicon solar cells this temperature is 270 o C, Evans and Florschuetz .
Illustrated in Fig. 4 is the correlation between solar cell efficiency and temperature. As temperature rises, efficiency experiences a decline attributed to heightened electron–hole recombination rates and alterations in the bandgap properties of materials.
