Solar assisted water splitting in a PEC is an attractive concept to store solar energy as hydrogen fuel but the effective efficiency of the process is too low for it to be a serious contender for commercialization. The most important component of the PEC to achieve efficient water splitting is a photo active anode that could effectively absorb photons and deliver holes for the oxygen evolution reaction. Hematite has many attributes that make it a good candidate material for a photoanode but it also has some deficiencies. This article reviews the state-of-the-art hematite-based photoanodes, with special emphasis on attempts made by researchers to overcome its drawbacks. The numerous research reports are categorized under distinct strategies such as nanostructuring, elemental doping, surface passivation, cocatalyst application, conducting template incorporation and heterostructures which are possible pathways to improve the performance of hematite. The scientific understandings of the operating mechanisms for each strategy are systematically presented and discussed, and the improvements achieved by different approaches are compared. Some cutting-edge strategies, such as heterojunctions, could be important and hematite based heterostructures are discussed. A developing interest in an emerging material, Fe 2 TiO 5 is also discussed and some of the important benefits of this material are presented. Finally, the importance of scaling up the technology is discussed and attention is drawn to some possible challenges on scaling up. The paper concludes with some future technology directions and prospects for hematite-based photoanodes.

Hydrogen is one of the cleanest, most favourable, and most practical energy transferors. However, its efficient generation, storage, and transportation are still a challenge. There are various routes available toward greener hydrogen. Solar-driven splitting is considered a cleaner method with no harmful emission and viability of up-scaling. Various semiconductors were studied for photo-electrochemical catalysis to improve overall efficiency of the system (i.e. Solar-to-Hydrogen (STH)). Here we offer an intense evaluation of scientific and technical aspects of available designing strategies' for photocatalysts and recent fruitful advancements towards product development. This review might act as a handbook for budding researchers and provide a cutting-edge towards innovative and efficient catalyst designing strategy to improve efficiency for working scientists.

“…For PEC-PV configuration, the photovoltage outputs of the sub-cells are crucial, especially the photovoltage generated by traditional solar cells i.e., silicon, CIGS and DSSC is not enough to drive water splitting reaction. [24,45,47] In this context, the relatively large open circuit voltages of the halide perovskite solar cells have made them attractive candidates as the photovoltaic components of solar fuel devices. [16,41,42,44] The multiple light absorber tandem PEC systems can easily harvest a significant portion of the solar spectrum and generate enough voltage to overcome the overpotential and thermodynamical potential for water splitting.…”

“…Due to the low open circuit voltages of conventional photovoltaic systems (Si, CuInGaS/Se, DSSC), many of the tandem designs have required the series integration of several solar cells to generate the photopotential required for splitting water. [24,34,45,47] These complicated approaches require a careful balance of the optical conversion efficiency. [44,63] Figure 7 shows a notable example of a hematite PEC electrode integrated with one rear perovskite PV cell.…”
