TL;DR: Results clearly demonstrate that the unique nanotubes structure can facilitate the propagation and kinetic separation of photogenerated charges, suggesting potentially important applications of the inorganic QDs sensitized TiO2 nanotube-array films in solar cell applications.
Abstract: Novel CdS quantum dots (QDs) sensitized TiO2 nanotube-array photoelectrodes were investigated for their photoelectrochemical (PEC) performance. The highly ordered TiO2 nanotube arrays were synthesized by anodic oxidation and CdS QDs were deposited into the pores of the nanotube arrays by a sequential chemical bath deposition method. It is found that the CdS QDs deposited in the pores of the TiO2 nanotube arrays may significantly increase the liquid junction PEC short circuit photocurrent (from 0.22 to 7.82 mA/cm2) and cell efficiency (up to 4.15%). These results clearly demonstrate that the unique nanotube structure can facilitate the propagation and kinetic separation of photogenerated charges, suggesting potentially important applications of the inorganic QDs sensitized TiO2 nanotube-array films in solar cell applications.
Abstract: This letter describes the fabrication and characteristics of high‐efficiency thin‐film CdS/CdTe heterojunction solar cells. CdS films have been prepared by chemical bath deposition and p‐CdTe films have been deposited by close‐spaced sublimation. A CdS/CdTe solar cell of greater than 1 cm2 area with an AM1.5 efficiency of 15.8% is reported.
Abstract: A high surface area pn-heterojunction between TiO2 and an organic p-type charge transport material (spiro-OMeTAD) was sensitized to visible light using lead sulfide (PbS) quantum dots. PbS quantum dots were formed in situ on a nanocrystalline TiO2 electrode using chemical bath deposition techniques.1 The organic hole conductor was applied from solution to form the sensitized heterojunction. The structure of the quantum dots was analyzed using HRTEM technique. Ultrafast laser photolysis experiments suggested the initial charge separation to proceed in the subpicosecond time range. Transient absorption laser spectroscopy revealed that interfacial charge recombination of the initially formed charge carriers is much faster than in comparable dye-sensitized systems.2,3 The sensitized heterojunction showed incident photon-to-electron conversion efficiencies (IPCE) of up to 45% and energy conversion efficiencies under simulated sunlight AM1.5 (10 mW/cm2) of 0.49%.
Abstract: Metal chalcogenide thin films preparation by chemical methods are currently attracting considerable attention as it is relatively inexpensive, simple and convenient for large area deposition. A variety of substrates such as insulators, semiconductors or metals can be used since these are low temperature processes which avoid oxidation and corrosion of substrate. These are slow processes which facilitates better orientation of crystallites with improved grain structure. Depending upon deposition conditions, film growth can take place by ion-by-ion condensation of the materials on the substrates or by adsorption of colloidal particles from the solution on the substrate. Using these methods, thin films of group II–VI, V–VI, III–VI etc. have been deposited. Solar selective coatings, solar control, photoconductors, solid state and photoelectrochemical solar cells, optical imaging, hologram recording, optical mass memories etc. are some of the applications of metal chalcogenide films. In the present review article, we have described in detail, chemical bath deposition method of metal chalcogenide thin films, it is capable of yielding good quality thin films. Their preparative parameters, structural, optical, electrical properties etc. are described. Theoretical background necessary for the chemical deposition of thin films is also discussed.

Abstract: A ZnO compact layer formed by electrodeposition and ZnO nanorods grown by chemical bath deposition (CBD) allow the processing of low-temperature, solution based and flexible solid state perovskite CH3NH3PbI3 solar cells. Conversion efficiencies of 8.90% were achieved on rigid substrates while the flexible ones yielded 2.62%.
