这个小企业技术转让（STTR）第二阶段项目的更广泛的影响/商业潜力是促进新的低成本和高效率太阳能电池的开发。这一工艺利用丰富的自然资源作为原材料，采用一种新颖的技术制造出可以印刷在塑料箔上的零件，大幅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STTR第二阶段项目提出使用行业成熟的狭缝式模具涂层技术开发可靠，可重复和具有成本效益的钙钛矿光伏（PV）器件升级，最终生产柔性和刚性，高效的钙钛矿太阳能电池（PSC）。在最近的研究中，钙钛矿太阳能电池的效率已经飙升至22%以上，现在可以与CdTe和硅基太阳能电池板相媲美。大多数研究实验室的钙钛矿太阳能电池设备是通过旋转铸造制造的，设备面积小于1平方米。厘米尽管钙钛矿太阳能电池技术取得了进展，但商业化需要解决三个基本问题：设备寿命，可控钙钛矿沉积和改进制造，特别是在可扩展性方面。该项目的目标是：1）生产用于尺寸为600-1200 mm及以上的大型太阳能电池板的混合钙钛矿（HP）狭缝模沉积溶液，2）构建用于钙钛矿-硅串联光伏电池的狭缝模涂覆溶液，和3）的方法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，并已被认为是值得通过评估使用的支持基金会的学术价值和更广泛的影响审查标准。

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.
