Organic photovoltaics(OPVs) have attractive advantages including solution-processability, flexibility and transparency. Semitransparent OPVs(ST-OPVs) are one of the most promising photovoltaic technologies applicable to building integrated photovoltaic(BIPV). Window-film-type ST-OPVs are simultaneously blocking UV and IR region and generating electrical energy. Herein, PEDOT:PSS with sequential post-treatment was utilized as top electrode with high conductivity. The optimized devices were semi-transparent with 10.8% of power conversion efficiency, average visible transmittance (AVT) of 26% and light utilization efficiency(LUE) of 2.81%. It was also suggested that the possibility of window films with the values of UV rejection, IR rejection, and total solar energy rejection (TSER) of 74.6%, 69.0%, and 60.0%, respectively. Therefore, window-film-type ST-OPVs will be very effective for both energy harvesting and heat insulating property.
