Hybrid inverted organic photovoltaic cells based on nanoporous TiO2 films and organic small molecules
چکیده انگلیسی

Solar cells based on nanoporous TiO2 films with an inverted structure of indium tin oxide (ITO)/TiO2/copper phthalocyanine (CuPc):fullerene (C60)/CuPc/poly(3,4-oxyethyleneoxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/Au were fabricated. The best overall photovoltaic performance undergoing a series of device optimization was achieved with the device of ITO/dense TiO2 (30 nm)/nanoporous TiO2 (130 nm)/C60:CuPc (1:6 weight) (20 nm)/CuPc (20 nm)/PEDOT:PSS (50 nm)/Au (30 nm). The device using the nanoporous TiO2 films has better photovoltaic properties compared to those using dense TiO2 films. Higher photovoltaic performances were obtained by introducing a coevaporated layer of C60:CuPc between TiO2 and CuPc. The stability of inverted structure was better than that of the normal device, which gives a promising way for fabrication of solar cells with improved stability.
