With a booming population, global food demand is increasing rapidly. Various methods have been proposed to alleviate heat stress and improve yields for agriculture in hot climates. However, the damage caused by high root temperatures cannot be avoided due lack of efficient regulation strategies. In this work, we investigate new soil cooling strategy based on daytime radiative film. This film has emissivity across atmospheric window along with reflectivity solar spectrum. temperature drop 12.5°C, germination rate Cherry Radish improved from 39.6% 81.3% after using mulch. field test during summer, mulch increases fresh weight yield Chinese cabbage 127.4% arrtibuting reduced stress..

Abstract Near‐infrared (NIR)‐absorbing organic semiconductors have opened up many exciting opportunities for photovoltaic (OPV) research. For example, new chemistries and synthetical methodologies been developed; especially, the breakthrough Y‐series acceptors, originally invented by our group, specifically Y1, Y3, Y6, contributed immensely to boosting single‐junction solar cell efficiency around 19%; novel device architectures such as tandem transparent photovoltaics realized. The concept of NIR donors/acceptors thus becomes a turning point in OPV field. Here, development NIR‐absorbing materials OPVs is reviewed. According low‐energy absorption window, here, (p‐type (polymers) n‐type (fullerene nonfullerene)) are classified into four categories: 700–800 nm, 800–900 900–1000 greater than 1000 nm. Each subsection covers design, synthesis, utilization various types donor (D) acceptor (A) units. structure–property relationship between kinds D, A units window constructed satisfy requirements different applications. Subsequently, variety applications realized materials, including OPVs, photodetectors, presented. Finally, challenges future next‐generation beyond discussed.

Abstract Symmetric conjugated molecules can be broken through suitable synthetic strategies to construct novel asymmetric molecules, which largely broaden the material library. In field of organic solar cells, fused‐ring electron acceptors (FREAs) with A‐DA'D‐A type backbone structure have attracted much attention and enabled power conversion efficiencies (PCE) exceeding 18%. Among them, Y6 is one most classic FREAs that derive many symmetric exhibit unique optoelectronic properties. Thus, in this review, focus on recent progress Y6‐derived containing a dipyrrolobenzothiadiazole segment, classified as following three categories: end group, central core side chain. The relationship molecular structure, properties, device performance discussed detail. Finally, future design directions challenges faced by kind photovoltaic materials are given.

Abstract Side‐chain modifications of non‐fullerene acceptors (NFAs) are essential for harvesting their full potential in organic solar cells (OSC). Here, an effective alkyl‐chain‐branching approach the Y‐series NFAs flanking meta‐substituted phenyl side groups at outer positions is demonstrated. Compared to BTP‐4F‐PC6 with linear m ‐hexylphenyl chains, two new named BTP‐4F‐P2EH and BTP‐4F‐P3EH developed bulkier alkyl chains branched β γ positions, respectively. These result altered molecular packing afford higher open‐circuit voltage devices. Despite blue‐shifted absorption branched‐chain NFAs, blends PBDB‐T‐2F enable improved short‐circuit current density corresponding devices owing more suitable phase separation better exciton dissociation. Consequently, OSCs based on yield enhanced device performance 18.22% 17.57%, respectively, outperforming BTP‐4F‐PC6‐based ones (17.22%). results highlight that side‐chain branching design has great optimizing properties promoting photovoltaic performance.
