A larger fill factor is desirable and corresponds to an I-V curve that is more square-like. Typical fill factors range from 0.5 to 0.82. Fill factor is also often represented as a percentage. Efficiency (η) Efficiency is the ratio of the electrical power output P out, compared to the solar power input, P in, into the PV cell. ...
