Abstract

Triton X-100, DMSO and TiO2 were blended with PEDOT:PSS to produce a PEDOT:PSS/DMSO/TX100/TiO2 CE. A bifacial DSSC based on the PEDOT:PSS/DMSO/TX100/TiO2 CE was fabricated, and its photovoltaic characteristics were obtained under simulated solar light of 100 mWcm−2. Under bifacial illumination, the DSSC with the Pt CE achieved a current density (Jsc) of 16.16 mAcm−2 and system efficiency (Esys) of 8.67% while the DSSC with the PEDOT:PSS/DMSO/TX100/TiO2 CE achieved a Jsc of 17.72 mAcm−2 and a Esys of 9.14%. PEDOT:PSS/DMSO/TX100/TiO2 CE is very stable, has a high transmittance, exhibits high electro-catalytic activity, and is an excellent substitute for the Pt CE.
