How does solar cell size affect module efficiency?
Module efficiency increases with cell size if the cells are split (up to +1.1%abs). For full cells significant electrical losses in the solar cell interconnection overcompensate higher active area shares and reduce module efficiency. We calculate the module temperature and find modules with smaller solar cells to be cooler (up to -2.8 K).

The photovoltaic effect is based on the creation of an electric current in a material, usually a semiconductor, upon light irradiation. When sunlight irradiates the solar cell, some photons are absorbed and excite the electrons, or other charge carriers, in the solar cell.
How does temperature affect photovoltaic solar collector efficiency?
The efficiency of photovoltaic solar collector deteriorates with increase in cell temperature, which is mostly affected by solar radiation intensity rather than ambient temperature, as incident solar radiations cannot be fully converted into electricity and unconverted solar radiation heats up the photovoltaic cell and increase its temperature.
