Abstract
Chalcogenide-based solar cells Cu(In,Ga)(S,Se)2 were developed using an in-situ sol-gel method and spin coating thin film deposition. The influence of chemical composition and thermal treatment were studied in detail. It was revealed that these variables are related to band gap changes and final device performance. Increasing in band gap experimental values (1.18 - 1.67 eV) was observed, due to the formation of solid solution of Ga (III) and S (-II) incorporation in the crystal lattice. Optimal device performance of 3,1 % efficiency of solar energy conversion was achieved for the Cu(In1-xGax)(S,Se)2 solid solution. [ABSTRACT FROM AUTHOR]
