When measuring solar cells, we often refer to current density, J, rather than just current, I. This allows researchers to compare devices with different active areas. The power conversion efficiency (PCE) of a device is the product of V OC, J SC and FF, divided by the radiant power into the solar cell (P in). P in depends on the light source that you use. It is therefore important
