“…Sunlight absorption, heat transfer and water transport are the three main factors, which need to be optimized to improve the utilization efficiency of solar energy for water evaporation [11][12][13][14]. Generally, materials with a high absorption over the whole solar spectrum, such as plasmonic nanoparticles [15][16][17][18], carbon materials [19][20][21][22] or black polymers [23][24][25][26], are adopted as the surface layer. The heat absorbed from sunlight irradiation is then expected to heat up water to facilitate water evaporation, instead of transferring Energies 2021, 14, 6077 2 of 12 to the water reservoir.…”

Solar vapor generation is emerging as one of the most important sustainable techniques for harvesting clean water using abundant and green solar energy. The rational design of solar evaporators to realize high solar evaporation performances has become a great challenge. Here, a porous solar evaporator with integrative optimization of photothermal convention, water transport and thermal management is developed using attractive Pickering emulsions gels (APEG) as templated and followed by interfacial engineering on a molecular scale. The APEG-templated porous evaporators (APEG-TPEs) are intrinsically thermal insulation materials with a thermal conductivity = 0.039 W·m−1·K−1. After hydrolysis, t-butyl groups on the inner-surface are transformed to carboxylic acid groups, making the inner-surface hydrophilic and facilitating water transport through the inter-connected pores. The introduction of polypyrrole layer endows the porous materials with a high light absorption of ~97%, which could effectively convert solar irradiation to heat. Due to the versatility of the APEG systems, the composition, compressive modulus, porosity of APEG-TPEs could be well controlled and a high solar evaporation efficiency of 69% with an evaporation rate of 1.1 kg·m−2·h−1 is achieved under simulated solar irradiation. The interface-engineered APEG-TPEs are promising in clean water harvesting and could inspire the future development of solar evaporators.

This mini-review discusses the progress made in the development of polymerized small-molecule acceptors (PSMAs) for use in all-polymer solar cells (all-PSCs). These PSMAs combine the advantages of both small-molecule acceptors (SMAs) and polymers. Various studies have been conducted using different building blocks to synthesize these acceptors, including indacenodithiophene and indacenodithienothiophene. They exhibit many advantages such as strong absorption in the near infrared region, high electron mobility, and appropriate energy levels, making them good candidate for PSAMs. The improved efficiency of all-PSCs is attributed to several factors, including stronger absorption, improved blend morphology, and redistribution of composition in the film. Additionally, new materials have been incorporated as third components in ternary organic photovoltaics, with some achieving high power conversion efficiencies of up to 17.0%. The development of new acceptors with different building blocks has resulted in improved stability and reproducibility in all-PSCs, paving the way toward high-performance and stable devices. Overall, these developments demonstrate significant potential for further advancements in the field.
