Title
Poly(o-phenylenediamine)/MWNTs composite film as a hole conductor in solid-state dye-sensitized solar cells
Abstract

All solid-state dye-sensitized solar cells were fabricated using in situ electrochemically polymerized poly(o-phenylenediamine)/MWNTs (PoPD/MWNTs) as a hole transport materiel. The electrochemical behaviors of PoPD/MWNTs indicated that the electron exchange efficiency improves obviously of PoPD after the addition of carbon nanotubes. The PoPD/MWNTs composite film was deposited on the dye anchored porous TiO2 electrode and I–V characterization was performed under simulated AM 1.5 illumination. Fabricated devices for the PoPD/MWNT composites prepared in 0.1 g/L MWNTs showed a photoresponse with an open-circuit voltage VOC of 479 mV and a short-circuit current density (ISC) of 0.572 mA/cm2 with the overall conversion efficiency of 0.13%, higher than those of the cell with only PoPD (i.e., ISC = 0.275 mA/cm2, VOC = 462 mV, FF = 0.35, η = 0.04%). It is obvious that the introduction of MWNTs to PoPD composites could improve the cell performance.
