Summary: Dye-Sensitized Solar Cells (DSSCs), also known as Gratzel cells, are a third-generation photovoltaic technology that shows promise in terms of simplicity, economic viability, and high power conversion efficiency. The use of zinc oxide (ZnO) coupled with graphene as the photoelectrode enhances charge transfer and reduces electron-hole recombination, leading to improved performance. This review examines the feasibility and performance enhancement of ZnO/graphene nanocomposite and its derivatives as photoelectrodes for DSSCs, including their structural features, optical properties, electron transport, and dye interaction. The limitations and potential solutions for ZnO/graphene derivatives as photoelectrodes are also discussed. The ZnO/graphene-based photovoltaic cells have demonstrated an efficiency of up to 11.5% with different dyes and electrolytes. Furthermore, the recent progress of ZnO/graphene as a viable alternative to titanium dioxide (TiO2) is thoroughly reviewed.

Summary: The photovoltaic performance of dye-sensitized solar cells (DSSCs) based on TiO2 and BaTiO3 was improved by hydrothermal treatment of the porous TiO2 film. The structural, optical, and morphological properties of the deposited titanium dioxide and barium titanate film were studied. The efficiency of the DSSC increased threefold after converting the porous titanium dioxide into barium titanate. The lifetime was longer in the case of using barium titanate, while the ideality factor was higher when using titanium dioxide.

Summary: Dye-sensitized solar cells (DSSCs) have the advantages of environmental friendliness, easy fabrication, and rich colors, making them promising for applications in architectural decoration and power supply for low energy devices. However, porphyrin dyes used in DSSCs still suffer from absorption defects and aggregation tendencies. In order to address these issues, various approaches have been developed to achieve panchromatic absorption and high efficiency.

Summary: This study demonstrates the tuning of ZnO nanosheet-nanowire morphology by adjusting the NaOH concentration in a low-temperature chemical bath, resulting in a variety of nano/microstructures with different sizes and aspect ratios. Photoluminescence spectra were mainly influenced by violet emission from Zn interstitial related defects formed during growth. In dye-sensitized solar cells, ZnO nanosheets with a thickness of 30-40 nm exhibited superior performance in terms of J-V characteristics and transport dynamics.

Summary: The research found that V-OC of DSSCs can be significantly increased by Mg-doping, and the Mg concentration in MZO affects the transport and recombination of electrons in MZO, which in turn influences the performance of the cells. Nanoparticles with a pure ZnO core and an MZO shell structure can help reduce the impact of increased transport resistance in MZO and utilize the improved V-OC.
