Abstract
The authors have developed suitable methods of Cu(In,Ga)Se2 thin-film formation for application in large-scale manufacturing equipment. Total-area solar cell efficiencies as high as 13.9% have been achieved on small-area cells by these methods. Large-area film thickness and VOC uniformity data are also presented. The film formation involves sequential deposition of compound selenides, Se, and Cu. The fill factor of some devices was improved by deposition of a thin terminal In-Se layer, and surface modification by chemical treatments also improved device performance
