Abstract

In this paper, a CIGS material based solar cell structure is proposed. The efficiency of the designed structure is improved by considering ITO (Indium Tin Oxide) as a front contact. The detailed analysis of the device is carried out thoroughly using SILVACO ATLAS. Various design parameters such as open-circuit voltage (Voc), the voltage at maximum power density, short circuit current density (Jsc), maximum output power (Pm), and fill factor (FF), are calculated. CIGS solar cell with ITO as a front contact gives an improved efficiency of 23.074%. Thus, the proposed solar cell is a suitable candidate for ultra-high efficiencies.
