چکیده
The determination of the electrical conversion efficiency (ηC) is particularly important to evaluate performance a solar cell. For evaluation by considering ideal cell characterized an absence parasitic resistances and using characteristic equation which corresponds equivalent diagram, we determine parameters such as: saturation current density (J0), short-circuit (Jsc), open-circuit voltage (Voc), maximum power point (Jm, Vm) fill factor (FF). determined fundamental semiconductor notions. effect ideality on various also highlited. results are applied heterostructures based CuInS2 CuInSe2. increases with raising (η) for model.
