ABSTRACT
A dye-sensitized solar cell (DSSC) is an unconventional opportunity for silicon solar cells, owing to their flexibility, transparency, and low cost. The necessity for DSSCs to capture more of the sunlight radiation was the motivating force for the fabrication of semiconductor materials based on high surface area. The constituents of DSSC syndicate form a solar cell device. The main components in DSSCs are the conducting substrate, dye, photoanode, catalyst, and electrolyte. The photoanode is a well-known element that generates the energy conversion efficiency. There are different photoanode materials that have been studied to date. Amongst photoanode materials, titanium oxide (TiO2) materials are extensively documented, explored, and considered. In this chapter, effort will be made to survey the strategies to advance the energy efficiency of TiO2-based photoanodes with the introduction of metal-organic frameworks (MOFs) in DSSCs to suppress the recombination rate and electron loss. It was seen that to attain a high conversion yield in DSSCs, it is for very fast collection of produced ion carriers before electron re-combination. This chapter is devoted to the TiO2 and MOF photoanode, their properties, and various improvement approaches.
