Solar‐driven interfacial evaporation (SDIE) has played a pivotal role in optimizing water‐energy utilization, reducing conventional power costs, and mitigating environmental impacts. The increasing emphasis on the synergistic co‐generation of water and green electricity through SDIE is particularly noteworthy. However, there is a gap of existing reviews that have specifically focused on the mechanistic understanding of green power from WEC systems, the structure‐activity relationship between efficiency of green energy utilization in WEC and materials design in SDIE. Particularly it lacks a comprehensive discussion to address the challenges faced in these areas along with potential solutions. Therefore, this review aims to comprehensively assess the progress and future perspective of green electricity from water‐electricity co‐generation (WEC) systems by investigating the potential expansion of SDIE. Firstly, it provides a comprehensive overview about materials rational design, thermal management and water transportation tunnels in SDIE. Then it summarizes diverse energy sources utilized in the SDIE process, including steaming generation, photovoltaics, salinity gradients effect, temperature gradients effect, and piezoelectric effect. Subsequently, it explores factors that affect generated green electricity efficiency in WEC. Lastly, this review proposes challenges and possible solution in the development of WEC. The timely emergence of this review will promote the sustainable use of energy.This article is protected by copyright. All rights reserved

“…The power generation of this power generation method is deeply dependent on the temperature difference between the upper and lower surfaces of the thermoelectric module, 39,46 and when the temperature of the material surface reaches the highest and the temperature difference shrinks because the body of water has absorbed the radiation from the sun, the power generation decreases rapidly with a large fluctuation amplitude. 47 In this paper, we recycle and reuse waste biomass tea residue and use directional drying technology to prepare porous aerogel with directionally aligned channels, which is inexpensive and simple to fabricate, and this aerogel is able to use the excess heat to drive the salinity gradient for power generation with solardriven interfacial evaporation, which improves the efficiency of energy utilization. We have optimized the traditional thermoelectric power generation model by discarding the additional thermoelectric module and using thermal energy as a catalyst for the salinity gradient power generation effect.…”

Solar-driven interfacial evaporation co-generation (SIE-CG) technology is of great significance in solving the problem of water and energy shortage. Herein, we report the ionic liquid-assisted alignment of waste biomass tea residue-based microcrystalline cellulose for aerogels (abbreviated as TPPA-5) with aligned channels for solar-driven interfacial evaporation cogeneration. In the ionic liquid, strong H-bonding is formed between the pyranoid rings of cellulose combined with the slow freezing technique, resulting in the microcrystalline cellulose being reoriented, which allowed TPPA-5 to form abundant aligned channels after solvent replacement and freeze-drying. These aligned channels enable the brine to form a localized circulating flow, which is conducive to the improvement of the TPPA's evaporation rate and salt resistance. The salinity gradient is naturally formed in the channel of TPPA, which enables TPPA-5 to show excellent power generation performance. The evaporation rate of TPPA-5 can reach 3.39 kg m −2 h −1 under 1 kW m −2 . With methanol as a highly polar proton solvent, the maximum output voltage obtained was 67.534 mV due to the overlapping electric double-layer effect formed by hydrogen protons on the TPPA surface, and the energy utilization efficiency is 95.95%. Moreover, TPPA-5 can purify pesticide-containing wastewater, which has the advantages of being recyclable and environmentally friendly, showing potential application value in the field of seawater desalination and steam co-generation.
