An integrated cell for the solar-driven splitting of water consists of multiple functional components and couples various photoelectrochemical (PEC) processes at different length and time scales. The overall solar-to-hydrogen (STH) conversion efficiency of such a system depends on the performance and materials properties of the individual components as well as on the component integration, overall device architecture, and system operating conditions. This Review focuses on the modeling- and simulation-guided development and implementation of solar-driven water-splitting prototypes from a holistic viewpoint that explores the various interplays between the components. The underlying physics and interactions at the cell level is are reviewed and discussed, followed by an overview of the use of the cell model to provide target properties of materials and guide the design of a range of traditional and unique device architectures.

Solar-induced sorption-desorption based atmospheric water harvesting (SSDAWH) has emerged as a promising technology to mitigate global water scarcity through moisture capture across broad relative humidity (RH) ranges using advanced sorbents. While metal-organic frameworks (MOFs) have demonstrated exceptional potential in water capture applications, their practical implementation faces two critical challenges: the persistent gap between laboratory research and field deployment, and sluggish desorption kinetics that severely constrain SSDAWH system efficiency. To address these limitations, a novel MOF-303-LiCl composite integrated with reactive black dye-grafted fibrous mats (LiCl@MOF-chelated black viscose nonwoven mat, LMBVNM) is developed, creating a photothermal sorbent platform that enables rapid and complete moisture cycling.

Traditional photocatalytic systems often face significant challenges in nanocatalyst recovery from aqueous solutions, hindering their practical implementation in industrial-scale wastewater remediation. In this study, graphitic carbon nitride (g-CN) metal-free heterostructure film was spontaneously coassembled at the gas-liquid interface, with a uniform film structure of g-CN, well-stacked graphene oxide, and hexagonal boron nitride over centimeters in size. The van der Waals heterostructure film exhibits excellent photocatalytic performance behavior and broadband photoperception from 450 to 550 nm.

Solar-driven hydrogen (H) evolution from liquid organic hydrogen carriers (LOHCs) by using rationally designed heterojunctions represents a transformative approach toward carbon neutrality. However, practical implementation is hindered by inefficient charge separation and transport, predominantly due to suboptimal interfacial engineering in conventional heterostructures. Here, dense Cu-O-Ti bonds are created between zero-dimensional (0D) CuO nanocrystals (2-3 nm) and two-dimensional (2D) TiO architectures via a mechanism mediated by unsaturated oxygen atoms, which serve as electron mobility highways to ease excited-state relaxation and recombination.

Solar-driven interfacial evaporation has garnered significant attention as a sustainable technology for freshwater production. However, its widespread application is impeded by challenges, such as complex fabrication processes, high costs, and vulnerability to pore clogging. Herein, we present an E-shaped evaporator constructed through in situ integration of a binary photothermal nanocomposite comprising reduced graphene oxide and molybdenum disulfide (rGO/MoS) onto a polyurethane sponge substrate.

Microalgae-based bioremediation offers an eco-friendly approach for water purification, yet its practical implementation is hindered by low degradation efficiency and poor toxin tolerance. Here, we propose a visible-light-driven nano-biohybrid strategy by integrating Chlorella ellipsoidea with TiO-Ag-AgCl photocatalysts to overcome these limitations. The constructed C.
