文摘

Photovoltaic properties of Ru^II(4,7-diphenyl-1,10-phenanthroline-disulfonic acid disodium salt)-bis(2,2¡ä-bipyridine), [Ru(L1)(bpy)₂](PF₆)₂, [K403] related to its adsorption behaviour onto the nanoporous titanium oxide are investigated in association with its water-soluble structure thanks to disulfonic acid disodium salt groups. Dye sensitized solar cell is fabricated from aqueous solution of water-soluble ruthenium complex. Devices are fabricated in a sandwich geometry using PEDOT:PSS counter electrode versus platinum counter electrode. Poly(3,4-ethylendioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) is coated on FTO conducting glass substrate by spin coating process and used as dye sensitized solar cell¡¯s counter electrode. Our device performance results show that PEDOT:PSS counter electrode in DSSC has reasonably good catalytic activity and can be used instead of platinum counter electrode. The energy conversion efficiency is significantly favourable for DSSC using PEDOT:PSS counter electrode. The optical and electrochemical behaviours of K403 are studied. Also cyclic voltammograms and estimated by density functional theory studies (DFT) are studied for calculating E_Homo and E_Lumo energy levels of ruthenium complex.
