Preparation and photoelectrochemical properties of TiO2 hollow spheres embedded TiO2/CdS photoanodes for quantum-dot-sensitized solar cells

Cu2O/TiO2 heterostructured hollow sphere with enhanced visible light photocatalytic activity

“…Nonmetallic elements, such as N [13] and F [4] were also applied to enhance the visible light photocatalytic activities of TiO 2 hollow microspheres. Moreover, coupling TiO 2 HS with materials sensitive to visible light, such as WO 3 [14], ZrO [15] or CdS quantum dot [16], has been proved a promising method to obtain visible light absorption for TiO 2 HS. However, metallic and non-metallic elements doping always leads to unstable materials which undergoes corrosion and the degree of doping is difficult to control.…”

Photoelectrochemical properties of In2Se3 thin films: Effect of substrate temperature

“…Currently, the investigations on PEC cells, mainly focus on the semiconductor materials with wide band gaps, such as TiO 2 [10][11] and ZnO [12][13], which respond only to ultraviolet light (accounting only 4% in solar spectrum). With aim of utilizing the solar energy more effectively, intensive efforts have been carried out to investigate the visible light (accounting 43% in solar spectrum) responsive semiconductors (λ > 400 nm) [14].…”

CdS Quantum Dot‐Sensitized Vertical TiO2 Nanorod Arrays by a Simple Linker‐Assisted SILAR Method

“…Before hydrothermal treatment, FTO conducting glass (approximately 1.5 cm × 2 cm) was ultrasonically cleaned for 30 min in a mixed solution of deionized water, acetone, and ethanol with volume ratios of 1:1:1. TiO 2 nanorod (NR) arrays were prepared by the conventional hydrothermal method . Typically, 30 mL deionized water and 30 mL concentrated hydrochloric acid (36.5%–38% by weight) were mixed in a 200 mL beaker.…”
