Solid-state dye-sensitized solar cells fabricated by coupling photoelectrochemically deposited poly(3,4-ethylenedioxythiophene) (PEDOT) with silver-paint on cathode

摘要

A PEDOT-based dye-sensitized solar cell (DSC) is successfully improved by coupling photoelectrochemically deposited PEDOT layer with an Ag paste-paint on the cathode. With a 9.3 μm thick mesoscopic nanocrystalline TiO_2 film, a maximum cell performance of 3.2% with relatively high V_oc of around 780 mV is achieved.
