A series of metal-free organic dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under standard AM 1.5G illumination at a ligh ...
We report on the synthesis, electrochem., photophys., and photovoltaic properties of a series of three org. dyads comprising a perylene monoimide (PMI) dye connected to a naphthalene diimide (NDI) or a fullerene (C60) for application in dye-sensitized sola ...
Two triphenylamine-based metal-free org. sensitizers, D35 with a single anchor group and M14 with two anchor groups, were applied in dye-sensitized solar cells (DSCs) with a solid hole transporting material or liq. iodide/triiodide based electrolyte. Using ...
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 ...
ZnO based dye-sensitized solar cells have been studied using N719 and Z-907 as sensitizing dyes, with and without adding water to the dye soln. The solar cells have been characterized using photoelec. measurements and the interface between the dye and the ...
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 ...
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 ...
TiO2, ZnO nanoparticulate(-np), and ZnO-nanorod(-nr) electrodes have been modified with FeS2 (pyrite) nanoparticles. Quantum size effect is manifested by a blue shift in both absorption and photocurrent action spectra. PIA (photoinduced absorption spectros ...
Photo-modulated voltammetry was used to det. the redox potentials of the diiodide radical (I2-·) in H2O, MeCN, and 3-methoxypropionitrile. Iodide/triiodide redox electrolytes were exposed to modulated blue light, resulting in I2-· generation. Using transpa ...
