Inorganic-Organic Hybrid Nanocomposites for Photovoltaic Applications
Hybrid photovoltaic concepts based on a nanoscale combination of organic and inorganic semiconductors are promising way to enhance the cost efficiency of solar cells through a better use of the solar spectrum,a higher ratio of interface-to-volume,and the flexible processability of polymers.In this work,two types of thin film solar cells have been developed.In both types of solar cells,poly-N-vinylcarbazole (PVK) is used as electron donor,cadmium sulfide (CdS) and titanium dioxide (TiO2) nanocrystals are used as electron acceptors,respectively.Since TiO2 has a wide band gap and can only absorb UV light,in the second type of solar cell,ruthenium dye is used as photo-sensitizer.The preliminary results of photoconductive and photovoltaic characteristics of these two inorganic-organic composites are presented.
