More details: Electrical and optical properties of indium tin oxide films (ITO) coated on soda-lime glass substrates have been investigated as a function of substrate temperature. Highly conducting and transparent films have been obtained at a substrate temperature of 350\°C and above. An increase in carrier concentration accompanied by a widening in optical band gap (the Burstein-Moss shift) have been observed with increasing substrate temperature. Enhancement of carrier concentration at higher substrate temperatures may be attributed to the presence of higher valency states of tin (Sn4+) occupying the indium sublattice of indium oxide. Previous reports indicate that ITO/Si heterojunction has extremely good photovoltaic properties.Films--Chemical Vapor Deposition;Electric Properti
