Achieving 45% efficiency of CIGS/CdS Solar Cell by adding GaAs using optimization techniques

no code implementations14 Sep 2023 Satyam Bhatti, Habib Ullah Manzoor, Ahmed Zoha, Rami Ghannam

The most promising results of our study show that adding the GaAs layer using the optimised values of thickness as 5 ({\mu}m) and carrier density as 1*1020 (1/cm) will result in the maximum PCE, VOC, FF, and JSC of 45. 7%, 1. 16V, 89. 52% and 43. 88 (mA/m2), respectively, for the proposed solar cell architecture.
