With efficiency more than 21%, polycrystalline Cu(In,Ga)Se2 (CIGSe) semiconductors present maximum efficiency among thin film solar cells, making them a promising material to develop solar cell modules. Most efficient CIGSe cells produced till date are Ga poor cells (≈7.5% Ga) having band gap (Eg) =1.2 eV, however cells with optimum band gap (according to solar spectrum) 1.4 eV (≈18% Ga) presented much lower efficiency. This degraded performance of wide band gap CIGSe lead to scientific debates for many years suggesting various theories behind its decline in performance. Beneficial properties of Grain boundaries (GBs) are one of the main reasons for high efficiency of CIGSe and modifications in GBs could be the reason for hindered performa...
