Effects of mesoscopic poly(3,4-ethylenedioxythiophene) films as counter electrodes for dye-sensitized solar cells

Investigation of electrodeposited cobalt sulphide counter electrodes and their application in next-generation dye sensitized solar cells featuring organic dyes and cobalt-based redox electrolytes

“…The photocurrent transient measurement (Fig. 8b) for the DSSC fabricated with 3, 5 and 6 h of sensitization time shows the absence of steady current generation, characteristic of the evolution of a diffusion limitation for the Co(III) complex, which is a phenomenon well known in DSSCs that employ Cobalt complexes [17,48,49]. In contrast, photocurrent transient of the DSSC fabricated using 4 h of sensitization time (Fig.…”

Improving catalyst stability in nano-structured solar and fuel cells

“…Another alternative organic catalyst material that has been used in DSCs is PEDOT [43]. Excellent catalytic performances have been achieved using PEDOT as CE catalyst material using different deposition methods including spin coating [67], chemically polymerization [75], electrochemical polymerization [76], spin casting followed by polymerization [77] and pulse potentiostatic electropolymerization [78]. Furthermore, PEDOT composites with other polymer materials, carbon composite materials, metal composite materials, metal oxide composite materials, metal nitrides and carbides composite materials have been used as CE catalyst materials in DSCs [43].…”

Effect of ZnO nanowire synthesis time on dye-sensitized solar cells

“…Recently, there were more and more research for photoelectrode [3][4][5] or counter electrode [6][7][8] in order to improve the efficiency of dye-sensitized solar cell. However, the performances of DSSC depended on the photoelectrode.…”
