“…Further details regarding the quantitative results are summarized in Table S12 (Supporting Information). Photostability, another crucial indicator for commercial applications, [ 51 ] was monitored for binary and ternary PST‐OSCs; the results are shown in Figure S24 (Supporting Information). Clearly, better stability was achieved in the ternary OSCs, that is, 80% of its initial PCE value could be maintained after 303 h of continuous illumination, whereas its counterparts only deliver 192 and 264 h.…”

Semi‐transparent organic solar cells (ST‐OSCs) have great potential for application in vehicle‐ or building‐integrated solar energy harvesting. Ultrathin active layers and electrodes are typically utilized to guarantee high power conversion efficiency (PCE) and high average visible transmittance (AVT) simultaneously; however, such ultrathin parts are unsuitable for industrial high‐throughput manufacturing. In this study, ST‐OSCs are fabricated using a longitudinal through‐hole architecture to achieve functional region division and to eliminate the dependence on ultrathin films. A complete circuit that vertically corresponds to the silver grid is responsible for obtaining high PCE, and the longitudinal through‐holes embedded in it allow most of the light to pass through,where the overall transparency is associated with the through‐hole specification rather than the thicknesses of active layer and electrode. Excellent photovoltaic performance over a wide range of transparency (9.80–60.03%), with PCEs ranging from 6.04% to 15.34% is achieved. More critically, this architecture allows printable 300‐nm‐thick devices to achieve a record‐breaking light utilization efficiency (LUE) of 3.25%, and enables flexible ST‐OSCs to exhibit better flexural endurance by dispersing the extrusion stress into the through‐holes. This study paves the way for fabricating high‐performance ST‐OSCs and shows great promise for the commercialization of organic photovoltaics.

The expected population growth and resulting increase in food and energy demands have become global concerns to be addressed with urgent and targeted actions. Agrivoltaics has recently emerged as the practice of co‐locating photovoltaic (PV) infrastructure and agriculture to alleviate land‐use competition between energy and agriculture production. However, PV and agriculture are highly dependent on the utilization of sunlight. Therefore, the design of a PV system is critical for maximizing electricity generation and plant biomass production. Perovskite solar cells (PSCs), as an emerging PV technology, attract intensive attention owing to low fabrication cost, high performance, and tunable transmission. Accordingly, PSCs show promising application in a net‐zero emission agrivoltaics ecosystem. In this perspective, the advantages of PSC‐integrated agrivoltaics are discussed by comparing with traditional PV technologies. Thereafter, the promising and sustainable way is proposed to employ PSCs for electricity generation, plant growth, and aquatic animal development in an agrivoltaics ecosystem. Lastly, a design principle is provided for tailoring PSCs for a sustainable agrivoltaics ecosystem to simultaneously solve the energy and food crises.

“…Bulk heterojunction (BHJ) organic solar cells (OSCs) have outstanding merits including low cost, flexibility, lightweight, and transparence toward desired wavelengths by selective light-absorption. − Thanks to the continuous efforts from numerous researchers, the power conversion efficiencies (PCEs) of the BHJ OSCs have engaged a rapid progress in recent years. , Low-cost and facile synthesis of organic solar cell materials starting from simple precursors in an atom-economical way will play a key role in the large-scale and practical application of this emerging technology. Up to date, Stille polymerization (i.e., C–Sn/C–Br cross coupling) has become the most widely used tool to the synthesis of OSCs polymers, which, however, requires complicate and harsh reaction conditions toward C–Sn prefunctionalization of monomers and produces stoichiometric organotin toxic byproducts, and the unavoidable Sn residue integrated into the polymer chains. − In this regard, there is an urgent need to develop environmentally friendly and atom-economic polymerizations to facilitate the scalable synthesis of π-functional polymers and realize the full potentials of OSCs in practical application.…”

Direct C−H arylation polymerization (DArP) using unfunctionalized C−H bonds as a coupling partner has emerged as a sustainable synthetic strategy toward π-functional polymers with minimized waste emissions and potentially having comparable optoelectronic performances with the polymers derived from the C−Sn bond-based Stille couplings. However, most of the reported DArP-derived π-polymers used in bulk heterojunction organic solar cells (OSC) still deliver power conversion efficiencies (PCEs) below 10%. In this work, the PBDB-T2F (i.e., PM6) polymer was synthesized, for the first time, by the tin-free DArP under optimized conditions, which affords a PCE up to 10.1% for OSC devices. Although the systematical comparison study by varied characterizations including gel permeation chromatography, UV−vis spectroscopy, BHJ devices, microscopies, and grazing incidence X-ray diffraction reveals that the DArP strategy still needs to be improved in terms of reactivity and regioselectivity compared to the Stille couplings, the preliminary yet promising results here obtained will provide the stimulus for the generalization of DArP to the atom-economic synthesis of high-performance πpolymers, and promote the integration of green chemistry with green energy.
