Solid State solar cells employing Sb2S3 and methylammonium lead  iodide (CH3NH3PbI3) perovskite absorber materials on mesoscopic TiO2 have been constructed to evaluate the charge transport limitations of hole conductors such as spiroOMETAD, CuSCN and CuI. The inorganic hole conductor such as CuI offer favorable valence band position, high p-type conductivity, and the compatibility of the solution deposition method with the organo-lead halide perovskite absorber. Photoelectrochemical and transient absorption studies that provide mechanistic and kinetic details of hole transfer at the semiconductor/hole conductor interface will be discussed.
