The role of a TiCl4 treatment on the performance of CdS quantum-dot-sensitized solar cells

Effects of incorporating PbS quantum dots in perovskite solar cells based on CH3NH3PbI3

“…6 shows the CV measurement results, and the curves exhibit clear reduction peaks. The oxidation peak of the TiO 2 valence band (~2.4 V vs. NHE) is not observed because it is not in the range of the test [32]. The CB levels can be calculated using the following equation: CB (eV) ¼ À(E redox onset þ 4.64) (eV), where 4.64 eV is the difference between the vacuum level of normal hydrogen electrode and the potential of the Ag/AgCl electrode (sat.…”

Facile Conversion Synthesis of Densely-Formed Branched ZnO-Nanowire Arrays for Quantum-Dot-Sensitized Solar Cells

“…The CdS quantum dots were coated on the branched ZnO nanowires by a successive ionic-layer adsorption and reaction (SILAR) [21] with 14-repeated cycles. Polysulfide electrolyte was prepared by dissolving 0.5 M Na 2 S, 1 M S, and 0.02 M KCl in methanol/water solutions (7/3 volumetric ratio) [22].…”

Organic-acid texturing of transparent electrodes toward broadband light trapping in thin-film solar cells

“…The key challenges for the solar-cell developments lie in the improvement of power-conversion efficiency and the reduction of fabrication cost [1][2][3][4][5][6][7][8][9]. For enhancing the power-conversion efficiency, much research has been focused on the light trapping to fully utilize broadband light with minimum optical losses [10][11][12][13].…”
