The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to greatly advance photovoltaics (materials for solar cells) made with special materials called perovskites, and enable high-speed printing of these solar cells on flexible underlying structures, known as substrates. This would enable large-volume manufacturing of these flexible solar cells for many applications. For instance, a freight truck trailer or refrigerated van covered by high-efficiency, lightweight and flexible solar panels would generate sufficient electricity to power all units on board, significantly reducing diesel fuel consumption and avoiding idle run during rest stops. Another potential use is retrofitting shading fabrics, such as those used on carports; this would not only effectively block sunlight and thus minimize car heating, but could also supply additional power for lighting and/or charging electric vehicles. This could also be used for forward operating bases or other remote military operations if integrated with tents, reducing diesel fuel demand and the associated risk to the supplying troops, as well as associated costs. The proposed project will develop a technology to enable large-scale manufacturing of high-performance fully-flexible perovskite solar cells. In spite of rapid progress in efficiency and low-cost potential from solution processing capability, perovskite solar cells still have to overcome a few obstacles before becoming economically competitive in the photovoltaic market. In particular, life span and the lengthy annealing time limit the capability for high-speed printing. The proposed technology innovation will address these two main issues through a novel process and material engineering. In this PFI-TT project, photonic irradiation will be utilized to achieve rapid layer-specific annealing for the metal oxide charge transport layers without damaging the underlying flexible substrate and perovskite absorber layer. The high-quality metal oxide films will not only improve solar cell stability by providing physical protection to the perovskite active layer, but also maintain the efficient charge transport and efficiency, achieving the best of both worlds. In addition, a particular polymer will be added into the perovskite precursor solution to form ultra-smooth and stable perovskite films. With the proposed rapid and layer-specific annealing and incorporation of a particular dendrimer in the perovskite absorber layer, highly-stable perovskite solar cells with efficiency above 20% on flexible substrates will be accomplished.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.

该创新合作伙伴关系 - 技术转化 (PFI-TT) 项目的更广泛影响/商业潜力是极大地推进由钙钛矿特殊材料制成的光伏（太阳能电池材料）的发展，并使这些太阳能电池能够在柔性材料上高速印刷。底层结构，称为基底。 这将使这些柔性太阳能电池的大批量生产能够用于许多应用。 例如，货运卡车拖车或冷藏车覆盖高效、轻质且灵活的太阳能电池板，将产生足够的电力为车上所有设备供电，从而显着减少柴油消耗并避免休息期间空转。 另一个潜在用途是改装遮阳织物，例如车库中使用的遮阳织物；这不仅可以有效阻挡阳光，从而最大限度地减少汽车发热，还可以为电动汽车照明和/或充电提供额外的电力。如果与帐篷集成，这也可用于前沿作战基地或其他远程军事行动，从而减少柴油需求和供应部队的相关风险以及相关成本。拟议的项目将开发一种技术，以实现高性能全柔性钙钛矿太阳能电池的大规模制造。尽管溶液加工能力在效率和低成本潜力方面取得了快速进步，但钙钛矿太阳能电池在在光伏市场上具有经济竞争力之前仍需克服一些障碍。特别是，寿命和较长的退火时间限制了高速打印的能力。拟议的技术创新将通过新颖的工艺和材料工程解决这两大主要问题。在这个 PFI-TT 项目中，将利用光子辐照来实现金属氧化物电荷传输层的快速层特异性退火，而不会损坏下面的柔性基板和钙钛矿吸收层。高质量的金属氧化物薄膜不仅可以通过为钙钛矿活性层提供物理保护来提高太阳能电池的稳定性，而且可以保持有效的电荷传输和效率，实现两全其美。此外，将特定的聚合物添加到钙钛矿前驱体溶液中以形成超光滑且稳定的钙钛矿薄膜。通过所提出的快速和层特异性退火以及在钙钛矿吸收层中加入特定树枝状聚合物，将实现在柔性基板上效率高于 20% 的高度稳定的钙钛矿太阳能电池。该奖项反映了 NSF 的法定使命，并被认为是值得的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来获得支持。
