Abstract: Solar photovoltaic cells are suitable alternatives to provide renewable, low-cost, and green energies. Dye-sensitized solar cells (DSSCs) have gained wide consideration owing to many properties such as transparency, low production costs, and the ability to operate in indoor lighting compared with the first generation of solar cells. Many investigations have been performed to improve the photovoltaic parameters in DSSCs by focusing on the photoanode layer. Among photoanodes, bifunctional ones, which can provide a set of essential and appropriate features in a structure, are so practical. Bifunctional photoanodes introduced as bi-layer or tri-layer photoanodes include some nanostructures as underlayer and some nanostructures with a remarkable surface area as over layer or light-scattering layer. This review can be a guide to the design and synthesis of bifunctional photoanodes with different structures. These photoanodes are useful not only for light-harvesting and light-scattering, but also for dye loading and the improvement of the JSC value and, thus, the increase of efficiency in DSSCs. This article presents recent achievements and strategies to design different bifunctional photoanodes, especially two types of photoanodes based on TiO2 and ZnO bifunctional materials.
