Abstract

Hybrid photovoltaic structures based on transparent conductive SnO2 and electrically conductive polypyrrole (PPy) were prepared. Nanocrystalline SnO2 is considered an n-type barrier and window layer on p-type PPy layer in cell structures. The surface morphology and thickness of the layers were studied using scanning electron microscopy. The optical absorbance data showed an increase of absorbance in contrast with PPy and SnO2. There was a red shift in absorbance wavelengths and a decrease in band gaps for the prepared PV structures. To investigate the electrical properties of the obtained structures, current-voltage characteristic was measured. The best structure showed an open-circuit voltage of 0.170 V, a short-circuit current density of 0.017 mA/cm2, a fill factor of 0.36 and power conversion efficiency of 0.076.
