Abstract

Ultra-thin MeSxHy (Me = In, Cu, Pb) heterojunctions were sandwiched between compact TiO2 and PEDOT:PSS layers. The MeSxHy layers were prepared by SILAR (successive ion layer adsorption and reaction). Intensity and temperature dependent current-voltage characteristics were investigated for small area solar cell structures. Highest values of open circuit voltage (0.9 V) were obtained for the In2S3/PbInxSyHz system annealed at moderate temperatures (150-200 °C) while PbInxSyHz did not act as an absorber. Largest values of short circuit current were reached for the In2S3/CuInxSyHz system in which both layers act as an absorber. The role of Pb and hydrosulfide for interface formation and defect passivation is discussed.
