AI 中文摘要
实验室规模的有机太阳能电池已展现出高效率及大规模生产的强大潜力。在扩大生产规模的制造技术中，卷对卷狭缝模涂覆提供了一条具有成本效益的可扩展制造途径。然而，在卷对卷制造过程中，涂层的实时评估和质量控制需要可靠的在线计量。在这项工作中，我们采用高光谱相机在卷对卷设置中对P3HT和OIDTBR活性层进行在线监测。使用多元曲线分辨率，我们可靠地解析了涂层中施主和受主贡献的空间分布。此外，通过拟合P3HT的吸收光谱，我们绘制了激子带宽，深入了解了聚合物的聚集和链相互作用。这些结果证明了高光谱成像作为大规模有机太阳能电池生产中实时监测和质量控制的强大工具的潜力。
英文摘要
Lab-scale organic solar cells have shown high efficiency and strong potential for large-scale production. Among the fabrication techniques for upscaling production, roll-to-roll slot-die coating offers a cost-effective route toward scalable manufacturing. However, reliable in-line metrology is needed for real-time assessment and quality control of the coating during roll-to-roll manufacturing. In this work, we employ a hyperspectral camera for inline monitoring of P3HT and OIDTBR active layers in a roll-to-roll setup. Using multivariate curve resolution, we reliably resolved the spatial distribution of donor and acceptor contributions in the coating. Furthermore, by fitting the absorbance spectra of P3HT, we map the exciton bandwidth, providing insights into the polymer's aggregation and chain interactions. These results demonstrate the potential of hyperspectral imaging as a powerful tool for real-time monitoring and quality control in large-scale organic solar cell production.
