A low-cost, high-efficiency solar cell based on dye-sensitized colloidal TiO2 films
THE large-scale use of photovoltaic devices for electricity generation is prohibitively expensive at present: generation from existing commercial devices costs about ten times more than conventionalExpand

Sequential deposition as a route to high-performance perovskite-sensitized solar cells
Following pioneering work, solution-processable organic–inorganic hybrid perovskites—such as CH3NH3PbX3 (X = Cl, Br, I)—have attracted attention as light-harvesting materials for mesoscopic solarExpand
