An energy conversion efficiency of up to 5.24% has been attained, under AM 1.5 G illumination for a new dye-sensitized solar cell using TH305, as a low cost org. dye, ((CH3)4N)2S/((CH3)4N)2S2, as an org. electrolyte and CoS as counter electrode. ...
Tungsten dioxide (WO2) nanorods were synthesized, which showed good catalytic activity for the redn. of triiodide to iodide. The dye-sensitized solar cell (DSC) using WO2 as a counter electrode (CE) reached a high energy conversion efficiency of 7.25%, whi ...
Electrochemical impedance spectroscopy (EIS) and transient voltage decay measurements are applied to compare the performance of dye sensitized solar cells (DSCs) using organic electrolytes, ionic liquids and organic-hole conductors as hole transport materi ...
Synthesized niobium oxides (Nb2O5 and NbO2) were applied for the first time as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). The DSC using NbO2 CE showed a higher power conversion efficiency of 7.88%, compared with that of the DSC using Pt ...
Zn stannate (Zn2SnO4) 27 nm particles were synthesized by hydrothermal treatment. Nano-porous Zn2SnO4 thin films were prepd. on conducting glass substrates and used as working electrodes in dye-sensitized solar cells (DSSCs). Their behavior was compared wi ...
Org. thiolate/disulfide redox couples were synthesized and were studied systematically in dye-sensitized solar cells (DSCs) from an org. dye (TH305). Photophys., photoelectrochem., and photovoltaic measurements were performed to get insights into the effec ...
Molybdenum sulfide (MoS2) and tungsten sulfide (WS2) are proposed as counter electrode (CE) catalysts in a I3-/I- and T2/T- based dye-sensitized solar cells (DSCs) system. The I3-/I- based DSCs using MoS2 and WS2 CEs achieved power conversion efficiencies ...
The electron transport and recombination in dye-sensitized TiO2 solar cells with different electrolytes have been investigated. The electrolytes were based on iodine-doped ionic liqs. (diethylmethylsulfonium iodide, dibutylmethylsulfonium iodide or 3-hexyl ...
We highlight the effect of the interfacial charge-transfer resistance at the counter electrode in dye-sensitized solar cells based on two cobalt redox shuttles, namely cobalt(III/II) tris(2,2'-bipyridine) and cobalt(III/II) tris(1,10-phenanthroline). Highl ...
The electron transport in dye-sensitized solar cells with a MOCVD (metal org. vapor deposition)-grown ZnO nanorod array (ZnO-N) or a mesoporous film prepd. from ZnO colloids (ZnO-C) as the working electrode was compared. The electrodes were of similar thic ...
