ZnO Nanowire/N719 Dye/Polythiophene-SWNT Nanocomposite Solid State Dye Sensitized Solar Cells

Abstract

Abstract:We designed and fabricated high efficiency solid state dye sensitized solar cells based on vertical ZnO nanowire arrays by utilizing a mixture paste of LiI, PMII and solid iodine as electrolyte. Poly thiophene -single wall carbon nanotube (PT-SWNT) composites were synthesized on FTO glass by in situ polymerization and employed as counter electrode to replace the conventionally used expensive Pt electrode. The initial results showed the power conversion efficiency of 2.87 % from the device with PPy-SWNT composite coated on FTO glass as counter electrode.

Study on Dye-sensitized Solar Cells based on ZnO Nanorods and Graphene Enhanced P3HT as HTM

“…They have the highest catalytic activity with the I3. However, due to their high cost, alternative materials are intensively studied such as carbon black [3] carbon nanotube [4] and conductive polymers [5]. Conducting polymers are promising candidates for DSSC or for solid-state dye sensitive solar cells counter electrodes because of their unique properties, including low cost, good conductivity, remarkable stability and good catalytic activity for I3-reduction [6].…”
