Spacecraft in terrestrial Solar System typically use PV cells to power their instruments. As the referenced Wikipedia article writes,
Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect.
PV meant for operation in vacuum differ from those meant for use on Earth.
Venus is closer to Sol than Earth. In orbit it receives greater radiant energy from Sol. It follows a PV cell may deliver more power. This may vary from one cell design to another.
For instance,
The ZTJ datasheet writes to convey the cell is capable of providing 2.726V (open circuit), and 17.4mA (short-circuit).
- How much more power could this cell deliver in Venerean orbit?
- Since all PV cells, regardless of design, would encounter similar solar radiance would it follow the power generation of all PV cells may increase in corresponding proportion?
