In this contribution, we present a new hybrid solar cell design. CuInS_2 nanoparticles were synthesized using a low temperature colloidal route with organic surfactants to form an inorganic nanoporous hole transporting electrode. A soluble fullerene derivate PCBM (1-(3-methoxycarbonyl)-propyl-1-1-phenyl-(6,6) C_(61)) was used for electron transport. We investigated the photovoltaic performance of the cells consisting of these CuInS_2 and PCBM bilayers with and without a surface-adsorbed RuL_2(NCS)/TBA(2:2) dye complex (where L= 2,2'-bipyridyl-4,4'-dicarboxylic acid; TBA= tetrabutylammonium). The cells containing the dye showed an improved photovoltaic response.
