I-Corps: Rapid Photonic Treatment for High-Speed Printing of Flexible Perovskite Solar Cells

这个I-Corps项目的更广泛的影响和商业潜力是为将光伏集成到广泛的新形式因素中提供了一条途径。该项目将首先探索将高性能、轻质柔性太阳能电池板集成到货运卡车拖车、遮阳织物和军用帐篷上的商业潜力。当货运卡车拖车的大外表面被高效太阳能电池板覆盖时，该技术可以显着提高柴油的整体效率。将柔性太阳能电池板改装到遮阳织物上，如天篷、遮阳篷和停车端口，可以潜在地为本地、潜在的离网供电。柔性太阳能电池板还将潜在地帮助军方应对在偏远地区发生的行动的电力需求。所有这些应用程序都依赖于该项目的核心技术所支持的新形式因素。这个I-Corps项目是基于克服钙钛矿太阳能电池主要障碍的核心技术，包括它们的寿命短，加工步骤长，以及在柔性基板上大面积制造的效率大幅下降。通常使用的退火方法需要在高温下长时间加热以获得所需的材料性能。因此，它们通常与高速打印不兼容。这里开发的技术实现了对目标层的快速层特异性光子处理，而不会损坏底层的柔性衬底和钙钛矿材料。这项创新技术通过高速印刷实现了耐用和全柔性钙钛矿太阳能电池的大规模生产。

The broader impact and commercial potential of this I-Corps project is to provide a path for integrating photovoltaics into a wide range of new form factors. The project will first explore the commercial potential of integrating high-performance, light-weight flexible solar panels onto freight truck trailers, shading fabrics, and military tents. When the large exterior surfaces of a freight truck trailer are covered by high-efficiency solar panels the technology can significantly improve overall diesel fuel efficiencies. Retrofitting flexible solar panels onto shading fabrics, such as canopies, awnings, and car parking ports can potentially allow for local, potentially off-grid, power sources. The flexible solar panels will also potentially help the military cope with their power needs for operations occur in remote locations. All these applications rely on the new form factors the core technology in this project enables.This I-Corps project is based on core technology that overcomes major obstacles in perovskite solar cells, including their short lifetime, lengthy processing steps, and substantial efficiency drops from large-area fabrication on flexible substrates. Commonly used annealing approaches require prolonged heating at high temperatures to attain desired material properties. Therefore, they are not typically compatible with high-speed printing. The technology developed here accomplishes a rapid layer-specific photonic treatment for the target layer without damaging the underlying flexible substrate and perovskite materials. This innovative technology enables large-scale manufacturing of durable and fully-flexible perovskite solar cells through high-speed printing.
