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: Due to their simplicity of manufacture, superior corrosion resistance, and low cost, carbon-based counter electrodes have gained unprecedented interest in dye-sensitized solar cells. However, issues such as poor surface adhesion and limited surface area of carbon counter electrodes have been a significant problem. To address these issues, researchers have used a hydrothermal technique to fabricate a novel carbon-based counter electrode. Through various tests, it has been found that the performance of this electrode is superior to traditional carbon-based electrodes.

Summary: The researchers built TiO2 cavities on the top of the TiO2 NP layer using carbonaceous microspheres as the template, forming TiO2 cavity/nanoparticle (C/NP) photoelectrodes for dye-sensitized solar cells (DSSCs). The optimized TiO2 C/NP electrode with 25 wt.% carbonaceous microspheres showed significant improvement in short-circuit current density (J(sc)) and power conversion efficiency (PCE), achieving a PCE of 9.08%, which is over 98% higher than that of the TiO2 NP electrode. Further investigations revealed that the enhancement in PCE is attributed to the competition between light scattering effect and charges recombination in the TiO2 C/NP photoelectrode.

Summary: In this study, graphene quantum dots (GQDs) were successfully synthesized via an electrochemical process and SERS signals were obtained from GQDs' Raman spectra. The D and G peaks of GQDs spectra were observed through Raman spectroscopy, with an increase in potassium chloride concentration leading to a 100-fold increase in Raman intensity at the D peak of GQDs compared to graphite. This indicates the potential feasibility of using GQDs for SERS applications compared to graphite.
