An alternative flexible electrode for dye-sensitized solar cells

With comparable transparency, flexibility, but a better conductivity, metal-mesh based PEN film provides an alternative low-cost electrode material to the conventional ITO/PEN film for flexible solar cell system. In this article, counter electrodes (CEs) prepared by coating metal-mesh/PEN with a mixture of PEDOT:PSS and carbon black nanoparticle (200–400 nm) were utilized in flexible dye-sensitized solar cells (DSCs). A high efficiency of 5.5 % was achieved with the DSC based on the metal-mesh/PEN CE, rivaling that of the DSC based on ITO/PEN CE.
