Power conversion efficiency (PCE) is one of the important factors in influencing overall performance dye-sensitized solar cells (DSSCs), and precise prediction PCE a feasible strategy for preparing highly efficient DSSCs devices. In this work, we designed series phenothiazine-based organic dyes by introducing different π-spacers including 4-isopropyl-4H-dithieno[3,2-b:2′,3′-d]pyrrole (DTP) 2,7-dihydronaphtho[1,2-d:5,6-d′]diimidazole (NDI) to tune their photovoltaic properties. The present...
We report a new strategy to fabricate multifunctional composite photoanode containing TiO2 hollow spheres (TiO2 -HSs), Au nanoparticles (AuNPs) and novel NaYF4 : Yb,Er@NaLuF4 Eu@SiO2 upconversion (UCNPs). The AuNPs are grown on the film including -HSs UCNPs by simple in situ plasmonic treatment. As result, an impressive power conversion efficiency of 14.13 % is obtained, which record for N719 dye-based dye-sensitized solar cells, demonstrating great potential cells toward commercialization....
Incorporating functionalized TiO2 microarchitectures or upconversion nanoparticles (UCNPs) into photoanodes is deemed to be two effective ways boost the photovoltaic performance of dye-sensitized solar cells (DSSCs). Nonetheless, studies combining and UCNPs for development composite photoanode films in DSSCs still remain scarce. In view this, we present a facile strategy design preparation multifunctional containing P25 nanoparticles, peanut-like (PN) microstructures,...

Developing metal-nitrogen-carbon (M-N-C)-based single-atom electrocatalysts for carbon dioxide reduction reaction (CO2 RR) have captured widespread interest because of their outstanding activity and selectivity. Yet, the loss nitrogen sources during synthetic process hinders further development. Herein, an effective strategy using 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4 ]) as a liquid source to construct nickel electrocatalyst (Ni-SA) with well-defined Ni-N4 sites on...
The present study quantitatively reveals the impact of coadsorbent and electron-withdrawing group on optoelectronic properties indoline dyes.
Excited-state intramolecular proton transfer (ESIPT) of four imidazole derivatives, 2-(2'-hydroxyphenyl)imidazole (HPI), 2-(2'-hydroxyphenyl)benzimidazole (HPBI), 2-(2'-hydroxyphenyl)-1H-phenanthro[9,10-d]imidazole (HPPI) and 2-(2'-hydroxyphenyl)-1-phenyl-1H-phenanthro[9,10-d]imidazole (HPPPI), were studied by the sophisticated CASSCF/CASPT2 methodology. The state-averaged SA-CASSCF method was used to optimize their geometry structures S0 S1 electronic states, CASPT2 calculations for...
Dye-sensitized solar cells (DSSCs) are deemed to show tremendous potential in clean, efficient, and inexpensive solar-energy technology, precise presentation on the solar-to-electricity nature of photosensitizers DSSCs may be a feasible strategy for developing highly efficiency stable cell devices. In this contribution, we have investigated several triphenylamine-based D–A−π–A by adopting different molecular design strategies such as exchange auxiliary acceptor π-spacer positions,...
Abstract We report a new strategy to fabricate multifunctional composite photoanode containing TiO 2 hollow spheres (TiO ‐HSs), Au nanoparticles (AuNPs) and novel NaYF 4 : Yb,Er@NaLuF Eu@SiO upconversion (UCNPs). The AuNPs are grown on the film including ‐HSs UCNPs by simple in situ plasmonic treatment. As result, an impressive power conversion efficiency of 14.13 % is obtained, which record for N719 dye‐based dye‐sensitized solar cells, demonstrating great potential cells toward...
