Dataset representing the effect of indirect band gap region of Cd-free AlGaAs buffer layer in Cu(In,Ga)Se photovoltaic cell.

The dataset of physical properties for the proposed CIGS solar cell with Cd-free AlGaAs buffer layer has been depicted in this data article. The cell performance outcome due to different AlGaAs buffer layer band gap is reported along with optimum solar cell performance parameters for instance, open circuit voltage [Formula: see text], short circuit current density ([Formula: see text], fill factor [Formula: see text], efficiency [Formula: see text], as well as collection efficiency [Formula: see text].
