This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is an opportunity to develop new applications that depend on mobile power and ultimately lower the cost of residential, commercial, and utility-scale solar power. The project seeks to develop extremely lightweight, flexible, and efficient photovoltaic (PV) modules using perovskite absorbers. These efficient, lightweight, and flexible modules may enable long-endurance unmanned aerial vehicles, supplemental charging for electric cars, and efficient solar power for commercial buildings with roofs too weak for typical solar panels. The anticipated advances may also lower installation, module, and total system costs. This SBIR Phase II project seeks to bring flexible and efficient perovskite technologies to the commercial production of solar power. The project seeks to develop a minimum viable product (MVP) that is targeted at solar-powered aerospace platforms and has the highest power density by weight (W/kg) of any commercial solar technology. Double-junction or tandem solar cells can reach far higher power conversion efficiencies than traditional single-junction cells (45% vs. 32%) by using two layers that absorb complementary parts of the solar spectrum. Such tandem cells have previously been too expensive for mainstream applications. This project uses perovskite materials to make tandem solar cells on flexible substrates at a lower cost than conventional cells by using high-throughput manufacturing and low cost materials. Through this project, the company will validate its first product line. It is expected that the efficient and lightweight technology may be able to be extended beyond airborne vehicles to other electric vehicles such as cars and trucks. Realizing these goals may pave the way for highly efficient and flexible solar cells at substantially lower costs than today’s leading solar technologies.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.

该奖项的全部或部分资金根据《2021 年美国救援计划法案》（公法 117-2）提供。该小企业创新研究 (SBIR) 第二阶段项目的更广泛影响/商业潜力是开发新应用的机会该项目旨在利用钙钛矿吸收器开发极其轻便、灵活和高效的光伏（PV）模块，并最终降低住宅、商业和公用事业规模太阳能的成本。灵活的模块可以实现长航时无人机、电动汽车的补充充电以及屋顶对于典型太阳能电池板来说太弱的商业建筑的高效太阳能发电，这些预期的进步还可以降低安装、模块和总系统成本。 SBIR二期项目旨在将灵活高效的钙钛矿技术引入太阳能商业化生产，该项目旨在开发一种针对太阳能航空航天平台且具有最高重量功率密度的最小可行产品（MVP）。瓦/公斤)通过使用吸收太阳光谱互补部分的两层，双结或串联太阳能电池可以达到比传统单结电池更高的功率转换效率（45％对32％）。此前，该项目使用钙钛矿材料在柔性基板上制造串联太阳能电池，其成本比使用高通量传统制造和低成本材料的电池要低。产品预计该轻质高效技术可能会扩展到机载车辆以外的其他电动车辆，例如汽车和卡车，这可能为以比当今低得多的成本实现高效、灵活的太阳能电池铺平道路。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。
