Abstract

MgO has not been explored as a counter electrode materials for dye-sensitized solar cells (DSSCs) due to its lack of electrical conductivity. However, herein, it is reported that MgO insulator with conductive poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) exhibited excellent performance as a counter electrode for DSSCs, leading to a high power conversion efficiency of 7.45%. Furthermore, it was revealed that the interface between MgO and PEDOT:PSS plays an important electro-catalytic role in the MgO/PEDOT composite counter electrodes.
