The first step of the integration of molybdenum clusters as new absorbers in all inorg. solar cells inspired from perovskite cells have been investigated via the fabrication of first cluster sensitized solar cells. The latter have been realized from the photoelectrodes obtained by chemisorption of the clusters on TiO2 and NiO films (resp. named photoanodes and photocathodes). Photovoltaic characteristics reveal that photoinduced electron or hole transfers can occur from the cluster units to the n- or p-type semiconductors resp. These first photovoltaic performances highlight the interest in using this inorg. cluster as new absorber for photo-electronical systems.
