STTR Phase II: Scalable fabrication of stable perovskite solar panels using slot-die coating technique

这一小型企业技术转让(STTR)第二阶段项目的更广泛影响/商业潜力是推动新的低成本和高效率太阳能电池的开发。这一工艺使用了丰富的自然资源作为原材料，使用一种新技术来制造可以在塑料箔上打印的部件，从而显著降低制造和安装成本。该项目将为太阳能电池行业开发先进的制造技术。该项目第二阶段计划开发一种可靠、可重复且经济高效的钙钛矿型光伏(PV)器件，使用行业证明的槽芯涂层技术，最终生产出灵活、坚硬、高效的钙钛矿型太阳能电池(PSC)。在最近的研究中，钙钛矿太阳能电池的效率已经飙升到22%以上，现在可以与镉镉和硅基太阳能电池板相媲美。大多数研究实验室的钙钛矿型太阳能电池器件都是通过旋转铸造制造的，器件面积不到1平方英尺。厘米。尽管钙钛矿太阳能电池技术取得了进步，但要实现商业化，还需要解决三个基本问题：器件寿命、可控钙钛矿沉积以及改进制造，特别是在可伸缩性方面。该项目的目标是：1)为600-1200 mm及以上的大型太阳能电池板生产混合钙钛矿(HP)槽芯沉积解决方案，2)为钙钛矿-硅串联光伏电池制造槽芯涂层解决方案，3)进行建模和可靠性研究以优化系统。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is to advance the development of new low-cost and high-efficiency solar cells. This process uses abundant natural resources as the raw material, using a novel technology to make parts that can be printed on plastic foils to significantly reduce manufacturing and installation costs. This project will develop advanced manufacturing technology for the solar cell industry. This STTR Phase II project proposes to develop a reliable, reproducible, and cost-effective upscaling of perovskite photovoltaic (PV) devices using an industry-proven slot-die coating technique, to ultimately produce flexible and rigid, highly efficient perovskite solar cells (PSC). The efficiency of perovskite solar cells has surged to over 22% in recent research and now rivals that of CdTe, and Si-based solar panels. Most research lab perovskite solar cell devices are fabricated via spin casting and have a device area of less 1 sq. cm. Despite the progress of perovskite solar cell technology, three fundamental issues need to be addressed for commercialization: device lifetime, controllable perovskite deposition, and improved manufacturing, especially in the area of scalability. This project's objectives are to: 1) produce a hybrid perovskite (HP) slot-die deposition solution for large solar panels sized 600-1200 mm and beyond, 2) build slot-die coating solution for perovskite-silicon tandem photovoltaic cells, and 3) conduct modeling and reliability studies to optimize the system.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
