Chalcogenides for photovoltaic applications

The global scenario related to energy demand and supply indicates danger of depletion of conventional energy sources. The photovoltaic energy source is one of the promising non conventional energy sources to solve energy crisis.Both the reduction of production cost and the improvement of cell efficiency are challenging for silicon technology. About 85% of the solar panels sold worldwide today are made of silicon. The domination of silicon will continue for some time until real breakthroughs take place within alternative technologies and low cost solar panels are manufactured on large scale.This book explores photovoltaic properties of zinc sulfide, indium selenide, zinc selenide, zinc indium selnenide, cadmium selenide and cadmium indium selenides with the help of ECPV cell, so that in next stage we can move forward and combine these basic interfaces to form more advanced photovoltaic devices. The relation between energy band gap, material resistance, contact angle and crystallite size has been established with electrochemical performance of the film. This work adds study of basic interfaces for future perspective in exploring the right materials for light harvesting.
