“…For most of the typical QDSSC devices, the J sc value is from several to more than ten mA cm −2 . 7,8,12,26,27,32–34 In this study, the QDSSCs based on the ZnO composite had a high J sc value, of >26 mA cm −2 , and high PCE values. Specifically, when the pore diameter of ZnO in the composite was 800 nm, the corresponding QDSSC achieved a maximum PCE value of 7.26%.…”

“…[3][4][5] ZnO nanorod (NR) arrays have demonstrated significant applications in DSSCs and QDSSCs. [6][7][8] ZnO NR arrays can provide a higher interfacial area and faster electrical pathways for the transport of electrons to increase the effective light trapping and power conversion efficiency (PCE). 9 However, the PCE of solar cells based on ZnO NRs are still at a relatively low level.…”

“…In [83], the influence of ZnO NR length and counter electrode material on the photovoltaic properties of CdS/ CdSe quantum dots co-sensitized ZnO NRs solar cells was reported. To fabricate a highly efficient quantum dot-sensitized solar cell (QDSSC), CdS/CdSe co-sensitized ZnO NRs and CuS grown via microwave-assisted hydrothermal method were employed as photo-electrode and counter-electrode, respectively.…”

In recent years, one-dimensional (1D) nanostructures, including nanorods, nanowires and nanotubes have been receiving a great deal of research attention due to their special and outstanding many characteristics that play a very important role in the manufacture of high-performance devices, including photodetectors, solar cells, light emitting diodes and power nano-generators, with novel functionalities. To date, a number of materials have been employed in the production of 1D structures for the fabrication of high-performance electronic and opto-electronic devices. Due to its stability, high conductivity, high electron affinity, and outstanding electron mobility, zinc oxide (ZnO) stands out among the others as a material that is particularly appealing to be employed in a variety of opto-electronic device applications. In this review article, we provide a brief overview of the most recent advances in popular synthesis methods and photovoltaic applications of 1D ZnO nanostructures, including our own recent studies. In particular, a special focus is given on the progress in 1D ZnO nanostructures based inorganic solar cells. Future research opportunities and challenges for solar cells based on 1D ZnO nanostructures are also highlighted.

Quantum dot-sensitized solar cells (QDSSCs) are significant energy-producing devices due to their remarkable capability to growing sunshine and produce many electrons/ holes pairs, easy manufacturing, and low cost. However, their power conversion efficiency (4%) is usually worse than that of dye-sensitized solar cells (� 12%); this is mainly due to their narrow absorption areas and the charge recombination happening at the quantum dot/electrolyte and TiO 2 /electrolyte interfaces. Thus, to raise the power conversion efficiency of QDSSC, new counter electrodes, working electrodes, sensitizers, and electrolytes are required. CdSe thin films have shown great potential for use in photodetectors, solar cells, biosensors, light-emitting diodes, and biomedical imaging systems. This article reviews the CdSe nanomaterials that have been recently used in QDSSCs as sensitizers. Their size, design, morphology, and density all noticeably influence the electron injection efficiency and light-harvesting capacity of these devices. A detailed overview of the development of QDSSCs is presented, including their basic principles, the synthesis methods for their CdSe quantum dots, and the device fabrication processes. Finally, the challenges and opportunities of realizing high-performance CdSe QDSSCs are discussed and some future directions are suggested.
