Photovoltaic Cell Efficiency
When temperature increases, the reverse saturation current of the solar cell increases and thereby reduces the open circuit voltage of the cell. This reduces the fill factor and the efficiency of the solar cell [115,116]. To some extent, this efficiency reduction can be lowered by trimming the reflection of the incident solar light.
