Abstract:
In this work. Sub-micrometre thick CulnSe2 films were prepared using different
techniques viz, selenization through chemically deposited Selenium and Sequential
Elemental Evaporation. These methods
are simpler than co-evaporation technique, which is known to be the most suitable
one for CulnSe2 preparation. The films were optimized by varying the composition
over a wide range to find optimum properties for device fabrication. Typical absorber
layer thickness of today's solar cell ranges from 2-3m. Thinning of the absorber
layer is one of the challenges to reduce the processing time and material usage,
particularly of Indium. Here we made an attempt to fabricate solar cell with absorber
layer of thickness <lmum. Here In2S3 was used as the buffer layer, replacing toxic CdS.
