“…The thermodynamically unfavorable influence is observed with decreasing the OH − concentration; the results are illustrated in Fig. 10 with the couple SO 3 2− /S 2 O 3 2− . The volume of hydrogen is larger at pH 13.1 because the band bending ˚is larger.…”

“…The greater volume of evolved H 2 with S 2 O 3 2− is easily understood in terms of the kinetic parameters since the band bending ( ˚) at the interface i.e. the driving force is nearly the same for both couples couple SO 3 2− /S 2 O 3 2− (0.46) and S n 2− /S 2− (0.41). Generated SO 3 2− through the reaction (3) follows two different oxidation ways according to parallel reactions (4) and (5) and this explains the larger volume.…”

“…The fact the photoactivity depends on pH could be a further argument in favor of the reaction (3) over the reaction (2). In addition the potential of the couple SO 3 2− /S 2 O 4 2− is located above VB and cannot be involved through VB process. With decreasing the pH, the couple SO 3 2− /S 2 O 3 2− become more oxidant and decreases the band bending ˚, which in turn increases the rate of the recombination process.…”

“…Hydrogen photogeneration from water over semiconductors (SC) has been the subject of many studies [1] and remains an attractive target and an ideal way of storing solar energy [2,3]. Accordingly, the development of new photoelectrode materials continue to attract great attention as an alternative for the light energy conversion [4].…”

“…They can be utilized by using a photoanode of band gap of 1.1 eV, thus opening the possibility of an efficient multiple band gap combination of thinfilm photovoltaic cell and thin-film photocatalyst for production of hydrogen and oxygen by water splitting. 1 Polycrystalline thin-film cadmium telluride ͑CdTe͒ solar cells, one of the PV cells used in this PEC setup, are amenable to economic mass production. CdTe solar cell has also shown laboratory efficiencies of 16.5% and module performance of over 10%.…”

Hydrogen is an alternative for the next generation of clean energy, especially in fuel developments with paths from high to low carbon content and low to high energy density. Hydrogen is free of carbon and when used releases no greenhouse gases or harmful substances. Hydrogen also has a gravimetric heating value (141.9 MJ kg −1 ) which is much higher than that of traditional fuels, such as petrol (47.5 MJ kg −1 ) and natural gas (55.5 MJ kg −1 ). [2] However, hydrogen production is not environmentally friendly; where over 90% originates from fossil fuels, emitting a large amount of CO 2 and pollutants. [3] Hence, "green hydrogen" processes with zero-pollution, sustainability, and high efficiency are a focus of the 21st century.In combination with solar energy, "green hydrogen" production is an opportunity. [4] A few technologies converting sunlight into hydrogen have been developed over the past century. However, low solar-to-hydrogen (STH) efficiencies restrict large-scale development. Recently, photovoltaic-electrolysis (PV-EC) and photoelectrochemical (PEC) systems have realized an STH efficiency of over 10% at laboratory scale, [5] which indicates scale-up potential. [6] Meanwhile, PEC technology has been demonstrated with numerous devices in the past half-century; such as "artificial leaf," [7] "integrated PEC," [5a] and "integrated PV-EC." [8] To develop green hydrogen further, we clarify the differences between PV-EC and PEC concepts, review the developments of both processes, summarize past studies, and estimate their potential for scale-up.In this review, we elaborate on the fundamental principles of PEC and PV-EC systematically and clarify their classifications. Then, we discuss the representative research on PV-EC and PEC chronologically, presenting the development trend. One of the essential aspects of this review is a technoeconomic analysis. Except for PV-EC, a large-scale PEC hydrogen production system (10 000 kg H 2 day −1 ) with a semi conductor-liquid junction (SLJ) is designed and analyzed. Conclusions and potential future developments for PV-EC and PEC are summarized. Note that this review is restricted to hydrogen production. The reader can refer to the literature related to the distribution, storage, and utilization of hydrogen, [9] which are essential to constructing a "hydrogen society in the future."Hydrogen, produced through a zero-pollution, sustainable, low-cost, and high-efficiency process, is regarded as the "ultimate energy" of the 21st century. Solar water-splitting techniques have immense potential to make the idea a reality. Two promising approaches, photovoltaic-electrolysis (PV-EC) and photoelectrochemistry (PEC), have demonstrated solar-to-hydrogen conversion efficiency over 10%, which is the minimum required for competitively priced, large-scale systems. Extensive studies of PV-EC and PEC devices reported within the past five decades show increasing design complexity. To accurately describe the gap between laboratory research and practical application, the basic principl...
