Solar Cells

Highlights

• Developing thin film solar photovoltaic cell with increased efficiency by fabricating from In, Cu and Ag doped SnS (p-type) nanostructures using CTAB assisted wet synthesis and physical vapour deposition. 

• Photovoltaic cells are developed from a multilayered CZTS/Ag/CZTS/Ag/CZTS (p-type) nanostructure without changing energy band gap and electrical property. Ag increases absorption coefficient of CZTS and thereby increases the cell efficiency. 

• SnS thin films and Ag, Cu and In doped SnS nanostructures grown by sputtering technique. The opto-electronic properties of the same have been studied thouroughly.
