N2 - Following recent developments in photoelectrochemical and photovoltaic-electrosynthetic systems, we present the benefits of III-V semiconductors for solar water splitting. On top of their interesting absorption and transport properties, III-V alloys and multijunction structures enable the highest solar-to-hydrogen conversion efficiencies. However, many obstacles still stand in the way of practical realization of III-V solar water-splitting systems. Various surface protection strategies are being developed to address the instability of III-V semiconductors in electrolyte. Meanwhile, multiple cost reduction approaches are being implemented, including the use of solar concentration, epitaxial lift-off or spalling for substrate reuse and monolithic or heterogeneous integration on silicon substrates. All these advancements make III-V photo-absorbers a promising route toward decarbonated hydrogen production and pave the way to its long-term deployment to real world applications.
