Manganese-Doped Copper Tin Telluride Absorber Layer-Sensitized Solar Cells.

Manganese2+-doped copper tin telluride nanoparticles (Mn2+:Cu2SnTe3 NPs), as an absorber layer, were grown using a chemical bath deposition (CBD) technique and demonstrated for solar cell applications. The cubical structure was formed on the WO3 surface with the band gap (Eg) of Cu2SnTe3 NPs decreased from 1.80 to 1.
