Electrodeposited MoTe2 Thin Films for Photoelectrochemical (PEC) Cell Applications
Thin films of transition metal chalcogenides, molybdenum ditelluride (MoTe2) have been electrodeposited cathodically on both indium tin oxide-coated conducting glass substrates and stainless steel substrates from H2MoO4 and TeO2 solutions. These MoTe2 thin films are useful as photovoltaic cell and p...
