Abstract
we described a facile in-situ wet chemical method to prepare SnO2 thin film on ITO glass substrate from preformed SnS thin film as sacrificial template. The chemical conversion process of SnS to SnO2 was studied. The SnO2 film and SnO2/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 SnO2/P3HT hybrid solar cell device showed an open-circuit voltage of 0.185V, a short-circuit current density of 0.366mA/cm2 and a fill factor of 0.247, corresponding to a power conversion efficiency of 0.0167%.
