Planar silicon solar cell
As expected, the open circuit voltage of the solar cell decreases at elevated temperature. This lowering of the open circuit voltage is due to an increase in the dark current of the solar cell due to elevated recombination rates. The maximum power achievable by the solar cell also decreases due to the same reason.
