Flexible conductive threads for wearable dye-sensitized solar cells

Flexible conductive threads were successfully fabricated on cheap insulating commercial thread substrates using a dip-coating method with conductive polymer PEDOT:PSS. The PEDOT:PSS improved the conductivity and catalytic performance of the threads. For the first time, threads were utilized to fabricate fiber-shaped dye-sensitized solar cells with 4.8% efficiency.
