Effect of sodium acetate additive in successive ionic layer adsorption and reaction on the performance of CdS quantum-dot-sensitized solar cells

Adsorption and Cation-Exchange Behavior of Zinc Sulfide on Mesoporous TiO2 Film and Its Applications to Solar Cells

“…Also, if we add 0.10 M Na­(CH 3 COO) into the Zn­(NO 3 ) 2 chemical bath to reach the same value of pH ≈ 6.2, the adsorption degree of ZnS was almost the same as that from Zn­(CH 3 COO) 2 when tested as the degree of color change after cation exchange to PbS, as shown in Figure S3. This critical effect of counteranion on the SILAR deposition of metal chalcogenides was similarly observed in the cases of PbS and CdS deposition. − In the current results, ZnS also followed this trend by electrostatic attraction or repulsion depending on the pH value of the solution and the PZC value of the metal oxide substrate dipped in that solution. Now, Zn 2+ with acetate anion clearly appears to be more adsorbed onto the meso-TiO 2 surface with a faster rate of deposition compared to the nitrate one only.…”

Lifetime elongation of quantum-dot light-emitting diodes by inhibiting the degradation of hole transport layer

“…Colloidal quantum dots (QDs) have been widely investigated due to their attractive characteristics, such as high photoluminescence quantum yield, low driving voltage, narrow full width at half maximum of the emission spectra, high color purity, tunable emission color, and cost-effective fabrication. [1][2][3][4][5][6][7][8][9][10] These characteristics make QDs potential electroluminescence (EL) material in quantum-dot light-emitting devices (QDLEDs) and a promising candidate for nextgeneration wide-color-gamut displays and solid-state lighting applications. Depending on the size and composition of QDs, the quantum connement effect allows them to modulate the emissive color to cover wavelengths ranging from the ultraviolet (UV) region to the near-infrared (NIR) region.…”

The Quantum Dot-sensitized Solar Cells (QDSSCs): A Review on Recent Achievements (2010-2021)

“…The proposed solutions have already resulted in considerable improvements in the QDSSCs' performance and stability. Many effective methods have been developed up to now to resolve the issues with QDSSCs such as an optimal design of QD sensitizers to balance sunlight absorption and electron injection (Chang, Li, Chiang, Chen, & Li, 2016;Elibol, Elibol, Cadırcı, & Tutkun, 2019;Liu, Chen, & Lee, 2016;Rahman et al, 2021), and achieving good sensor coverage by immobilizing pre-synthesised QDs on semiconductor oxides, (Alavi, Rahimi, Maleki, & Hosseini-Kharat, 2020;Y. Fu et al, 2017;Goodwin et al, 2018;Halder, Ghosh, Ali, Sahasrabudhe, & Bhattacharyya, 2018;Manjceevan & Bandara, 2018).…”
