Influence of 4-tert-butylpyridine/guanidinium thiocyanate co-additives on band edge shift and recombination of dye-sensitized solar cells: experimental and theoretical aspects

New D–π–A dyes incorporating dithieno[3,2-b:2′,3′-d]pyrrole (DTP)-based π-spacers for efficient dye-sensitized solar cells

“…In order to further study the relationship between dye structures and device performances, the charge density (d n ) at open circuit and the electron lifetime (s) as a function of charge density were measured by controlled intensity modulated photovoltage spectroscopy (IMVS). [38][39][40] The results indicate that the introduction of 10-phenyl-10H-phenothiazine and truxene onto DTP spacers of JW1 and JW2 is benet to enhance the photovoltaic performances of DSSCs by more efficiently reduce electron recombination, as compared to the introduction of 4hexyloxyphenyl onto DTP spacers of JW3. As shown in Fig.…”

Enhanced Photoelectrochemical Performances in Flexible Mesoscopic Solar Cells: An Effective Light‐Scattering Material

“…Aiming to meet the commercialization needs, various thin film device technologies have been developed to reduce the material and manufacture costs of solar cells . Among them, dye‐sensitized solar cell (DSC) technology is a promising candidate possessing benefits such as abundance of available materials, relatively low material and manufacture costs, various outdoor/indoor applications, as well as an industrial production desired low‐tech construction process . In the middle of a DSC device, dye molecules attach on mesoporous semiconductor network, normally TiO 2 .…”

Poly(ethylene glycol)–poly(propylene glycol)–poly(ethylene glycol) and polyvinylidene fluoride blend doped with oxydianiline-based thiourea derivatives as a novel and modest gel electrolyte system for dye-sensitized solar cell applications

“…[33][34][35] The organic additives 43,44 utilized such as 4-tert-butyl pyridine (TBP) and guanidinium thiocyanate (GuSCN) can inuence the downward displacement of TiO 2 to be continued with its negative potential shi. [36][37][38][39][40]47 Moreover, they act as a replacement for excellent metal oxide nano-llers. Organic additives preferably play a well-expressed role in many energy applications such as OLEDs 41 and DSSCs.…”
