Charging supercapacitors with small solar cells
I tested this circuit with two IXOLAR KXOB25-04X3F cells in parallel and also a PV cell of size 25x30mm bought from a well known Chinese online shop. This is supposed to have an open-circuit voltage of 1V and a short circuit current of 80mA. The single PV cell from China perform slightly better with a surface ca. 50% larger.

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.
