Effective iron-molybdenum-disulfide counter electrodes for use in platinum-free dye-sensitized solar cells

Insights into MoS 2 and its composites for dye‐sensitized solar cells

“…In addition, it maintained its electrocatalytic activity over 500 consecutive CV cycles. Moreover, it showed the best overall performance of 8.67% which is higher than all the other CEs (PCE of 7.20% for FeS 2 , 7.38% for MoS 2, and 8.18% for Pt) 89 . The nanocube morphology of the Co 3 S 4 /MoS 2 composite is attracting attention since it showed a PCE of 8.96% which is higher than the Pt CE (7.77%).…”

“…86 The vertically grown FeS 2 / MoS 2 nanosheets on flexible Ti foil demonstrated superior charge-transfer ability with abundant catalytic active sites, an enhanced surface area, and excellent electrochemical stability. 89 The feather duster-like morphology of NiS@MoS 2 showed excellent electrocatalytic activity toward the reduction of triiodide ions and also exhibited a large specific surface area. 90 Interestingly, Prussian-blue analog-derived MoS 2 composites showed a nanocubic morphology.…”

“…In this hybrid, CoS contributed with more active sites whilst MoS 2 offered conductivity which collectively displayed the highest PCE of 7.48% 86 .

An attractive feature here is the morphology which can be controlled by adjusting the reactant ratios.…”

Enhanced performance of CdS/CdSe quantum dot-sensitized solar cells by long-persistence phosphors structural layer

“…To reach its theoretical performance, considerable studies have been carried out [14][15][16]. It is found that optimizing the efficiency of charge collection, reducing the charge recombination and promoting the separation of electronhole pairs are effective methods to improve the PCE of QDSSCs [17][18][19][20][21]. Moreover, expanding the light absorption range and enhancing the light absorption efficiency have significant effect on the PCE [22].…”
