Green Energy Materials group
Currently the Green Energy Materials group is interested to explore the use of earth abundant semiconductor such as CZTS in energy conversion devices. It is proposed to develop the low cost solution processed CZTS based absorber layer for highly efficient thin film solar cell devices, without using toxic solvents. The nano composites of such visible light absorbers with various n-type metal oxide nanostructures as well as graphene oxide based materials will be prepared and their optical properties will be explored for various energy related applications including photocatalysis. The group is also working on novel rare earth free luminescent materials for solid state lighting applications.
