Against the backdrop of global acceleration toward carbon neutrality goals, organic photovoltaics (OPV) is transitioning from laboratory to industrial scale, leveraging its unique advantages of lightweight, flexibility, semi-transparency, solution processability, and environmental friendliness. As a premium biochemical database and materials brand under Watson, ChemWhat has focused extensively on core functional materials for organic photovoltaics in recent years, systematically enhancing its product portfolio. The comprehensive range covers everything from classic fullerene systems to cutting-edge non-fullerene acceptors (NFAs), high-performance polymer donors, and key intermediates, fully supporting the breakthrough requirements of research institutions and industrial clients in efficiency, stability, and mass production processes. 1. Strategic Positioning: Complete Coverage of OPV Value Chain Key Materials ChemWhat’s product strategy closely aligns with current organic solar cel...

非富勒烯受体（NFA）平台：涵盖当前主流明星分子 Y6（CAS: 2304444-49-1）、N3（即PC61BM的同系物，CAS: 2640657-07-2）、BTP-eC9（CAS: 2598965-39-8）、PY-IT、D18/D18-Cl（CAS: 2433725-54-1 / 2433725-53-0）及 L8-BO（CAS: 2668341-40-8）等。其中，D18 与 L8-BO 的组合表现尤为突出——在相同标准器件结构下，实现了 20.24% 的PCE，Voc达 0.92 V，Jsc为 26.42 mA/cm²，FF高达 83.26%，代表了目前溶液处理型OPV的效率巅峰。值得一提的是，作为该产品线中的经典代表，富勒烯C60衍生物 PC61BM 依然发挥着不可替代的作用。作为一种公认的基准材料，PC61BM不仅在有机太阳能电池（OSC）中广泛应用，更在钙钛矿太阳能电池（PSC）领域扮演着关键角色——它既是高效的电子传输层（ETL），也是优异的晶界钝化剂。为满足高校、研发机构及商业制造商的差异化需求，ChemWhat已将该产品标准化为两个纯度等级：99.5%用于常规研究，99.9%则专为高精度器件制备而设。ChemWhat不仅实现上述NFA产品的稳定供应，更通过优化合成路线，将关键中间体纳入标准品目录，助力客户自主开发新型受体结构。 https://www.youtube.com/watch?v=ZPw-35OKxb4

As the world races toward net-zero, organic photovoltaics—or OPV—are stepping into the spotlight. Lightweight, flexible, semi-transparent, and printable, OPV is no longer just a lab curiosity—it’s powering the future of wearable tech, smart windows, and indoor energy harvesting. At the heart of this revolution is ChemWhat, a premium materials brand from Watson International, delivering the high-purity, structurally precise molecules that turn scientific breakthroughs into real-world devices. ChemWhat’s strength lies in its complete OPV ecosystem—from donors and acceptors to critical intermediates. Its polymer donors like PM6 and PTQ10, paired with next-gen non-fullerene acceptors such as L8-BO and PY-IT, are setting new efficiency records. In standard device architectures, PM6:L8-BO achieves an impressive 18.78% power conversion efficiency, while D18:L8-BO soars to 20.24%—among the highest ever reported for solution-processed solar cells. And PTQ10:PY-IT delivers exceptional current ou...

A standout component of this lineup is the Fullerene C60 derivative, PC61BM. Widely recognized as a benchmark material, PC61BM plays a pivotal role not only in Organic Solar Cells (OSCs) but also in Perovskite Solar Cells (PSCs), where it functions as a highly efficient Electron Transport Layer (ETL) and grain boundary passivator. To address the varied requirements of universities, R&D centers, and commercial manufacturers, ChemWhat has standardized this product into two distinct purity levels: 99.5% for general research and 99.9% for high-precision device fabrication.

Beyond established expertise in inorganic rare earths and perovskite raw materials, ChemWhat has successfully redefined its presence in the field of organic optoelectronics.
