CdS and CdSe quantum dots subsectionally sensitized solar cells using a novel double-layer ZnO nanorod arrays

Multiworking Electrode Flexible Fiber-Type Quantum Dot-Sensitized Solar Cells

“…2(d), lattice fringes with 0.28-0.32 nm interplanar crystal spacings are clearly visible. According to some previous researchers' works, these interplanar crystal spacings arise from the (1 0 0) crystal plane in ZnO and (1 0 1) crystal planes in CdS, respectively [60], [61]. These results confirm that the ZnO nanorod surfaces were successfully covered with the CdS QDs after the sensitization via the chemical bath deposition.…”

Enhanced charge-carrier transfer by CdS and Ag2S quantum dots co-sensitization for TiO2 nanotube arrays

“…The flat heterojunction solar cell based on TiO 2 nanocrystalline thin membranes and PbS QD thin membranes boasts a PCE value of 5.1% [19]. Ensuing in-depth studies reveal that co-sensitization with two types of QDs, such as PbS and CdS [20,21], CdTe and CdSe [22,23], CdS and Ag 2 S [24,25], affords improved photoelectrochemical performances over sensitization with just one type of QDs like CdS, PbS, or CdSe [26][27][28]. Nevertheless, the kinetics of interfacial separation and transport together with recombination for photogenerated charge carries after co-sensitization awaits deep studies.…”

CdSe quantum dot sensitized solar cell based hierarchical branched ZnO nanoarrays

“…Branched growth was achieved by another growth (Fig. 1d), the mixed aqueous solution (100 ml) of 40 mM Zn(NO 3 ) 2 and 80 mM NaOH was used as the growth solution [14]. The films were immersed the growth solution for 30 min at 83°C, and after the reaction was complete, the grown ZnO NAs were thoroughly rinsed with Milli-Q water and dried at 200°C in air.…”

“…The procedure that was followed for the sensitization of ZnO NAs with CdSe QDs is based on some references [14]. 0.133 g of SeO 2 was dissolved in 40 mL of deionized water (30 mM) in the round-bottom flask, and stirred for about 3 min with N 2 gas.…”
