For most crystalline silicon solar cells the change in VOC with temperature is about −0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around −0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is −0.20 to −0.30%/°C, depending on how the cell is made.
The design of the solar photovoltaic (PV) module is done by connecting required number of cells in series and shunt to get the desired output, thereby increasing the efficiency. However, the performance of the PV system gets affected by the environmental conditions such as change in solar insolation and temperature.
It can be shown that for a high-quality solar cell (low RS and I0, and high RSH) the short-circuit current is: It is not possible to extract any power from the device when operating at either open circuit or short circuit conditions. The values of IL, I0, RS, and RSH are dependent upon the physical size of the solar cell.
