Optimization of hydrogenated amorphous silicon thin films and fabrication of solar cells on flexible substrates at low temperature

Abstract

Solar energy is one of the alternatives for renewable energy generation It is extracted directly in the form of electrical energy from solar radiation using photovoltaic PV solar cells The PV market is dominated by crystalline silicon based solar cells However thin film solar cells are becoming increasingly important because these are deposited at relatively low temperatures and as such offer the possibility to produce flexible and light weight solar panels The flexible substrates have a
