The interconnected CaCO3 coated SnO2 nanocrystalline dye-sensitized solar cell with superior performance

Size and shape fine-tuning of SnO2 nanoparticles for highly efficient and stable dye-sensitized solar cells

“…The development of UV post-treatment, 11 new dye-oxide linkages, 12 well-dened SnO 2 morphologies as nanowires 13 and nanoowers, 14 mesoporous agglomerates, 15 or well-ordered mesoporous SnO 2 layers 16 led to slight improvements with PCE reaching 3% in some cases. Besides, introduction of an interfacial layer on the SnO 2 surface using other materials such as TiO 2 9b,17 or CaCO 3 , 18 or by addition of ZnO nanoparticles 9e yielded higher efficiencies.…”

Efficient light-scattering functionalized TiO2 photoanodes modified with cyanobiphenyl-based benzimidazole for dye-sensitized solar cells with additive-free electrolytes

“…In addition, surface passivation of TiO 2 photoanodes by carefully optimizing and controlling the thickness of an ultrathin insulator layer, such as metal oxide, 15,16 carbonates, 17 organic silane 18 or poly(methylsiloxane) 19 has been applied to improve the performance in DSSCs. 4,[15][16][17][18][19][20] Recently, dendrons 21 and metal-organic frameworks (MOFs) 22 coated on TiO 2 photoanodes also effectively enhance the device performance of DSSCs. Co-adsorbants, such as phosphonic acid and bis-(3,3dimethy-butyl)-phosphinic acid 23 and donor-acceptor type molecules, 24 can also be applied for the surface modification of TiO 2 photoanodes to assist favourable packing of dye molecules by avoiding aggregation.…”

Effect of Au nano-particles on TiO2 nanorod electrode in dye-sensitized solar cells

“…Initial demonstrations of DSSCs were based on dye sensitization of porous nano crystalline semiconductors like TiO 2 . There are numerous studies on the potentials of improving the efficiency of DSSCs by using other semiconducting metal oxides, such as Nb 2 O 5 [3], CeO 2 [4], ZnO [5,6], and SnO 2 [7] and composite oxide materials [8,9].…”
