SnO2 films: In-situ template-sacrificial growth and photovoltaic property based on SnO2/poly(3-hexyl-thiophene) for hybrid solar cell

Abstract we described a facile in-situ wet chemical method to prepare SnO 2 thin film on ITO glass substrate from preformed SnS thin film as sacrificial template. The chemical conversion process of SnS to SnO 2 was studied. The SnO 2 film and SnO 2 /P3HT was characterized by several techniques, such as powder X-ray diffract meter (XRD), Raman spectrometer, scanning electron microscope (SEM), atomic force microscope (AFM) and UV–vis spectrophotometer in detail. The new SnO 2 /P3HT hybrid solar cell device showed an open-circuit voltage of 0.185 V, a short-circuit current density of 0.366 mA/cm 2 and a fill factor of 0.247, corresponding to a power conversion efficiency of 0.0167%.
