    Dye-sensitized solar cell (DSSC) has been studied widely due to its efficiency and the simplicity of manufacturing technology. Much research has been performed to improve the photovoltaic output parameters in DSSC by modifying the photoanode layers. The efforts to investigate DSSC mainly focus on how to increase light absorption, speed electron transport in circuits, and reduce charge recombination. This review discusses the process of charge recombination and the paths of occurrence in a DSSC. Recombination occurs when the electrons in the conduction band fall into the valance band holes and is considered an unnecessary process in DSSC. Due to the recombination process, the photocurrent and the photovoltage are reduced, leading to lower power conversion efficiency. Hence, the ways to overcome the charge recombination process were also discussed.

    This review focused on the synthesis methods of tin oxide (SnOâ‚‚) nanoparticles as a photoanode for dye-sensitized solar cell (DSSC) and how it impacts the performance. There are many different techniques and various nanoparticles were produced and usually characterized by X-ray diffraction (XRD) to determine crystalline structure of SnOâ‚‚, scanning electron microscopy (SEM) to examine the surface morphology and size details and J-V solar simulator to verify current-voltage characteristics. In summary, considering all the methods reviewed, sol-gel is reported as the best method to produce SnOâ‚‚ nanoparticles for DSSC fabrication with the highest efficiency recorded of 3.96%.
