A thin-film metal-amorphous chalcogenide semiconductor Schottky barrier solar cell between Bi and n-type As2Se3:Bi has been fabricated by low-temperature diffusion of vacuum evaporated bismuth into a p-type a-As2Se3 film. The dominant current transport mechanism in the junction is established to be tunneling via recombination states. Typical open circuit voltage and short circuit current density of the solar cell are 300 mV and 140 μA/cm2, respectively.
