The effect of conductive polymer layers deposition of poly(3,4-ethylenedioxythiophene) (PEDOT) on the surface photovoltage of CuInS2 (CIS) was studied. The PEDOT layer is considered as an alternative to the traditional window top layer or contact layer on the CIS absorber layer in the cell structure. It was shown, that the deposition of PEDOT films on the surface of CIS decreases the height of the potential energetic barrier and increases the efficiency of charge carriers transport through the CIS/PEDOT interface. Our results confirm the possibility of using the conductive polymer films as organic buffer-window layers in hybrid organic-inorganic photovoltaic structures.
