Perovskite solar cells (PSC) have emerged in the past decade as an exciting, low-cost, renewable-energy technology, and the efficiency with which they convert sunlight to electricity is now on par with silicon solar cells. However, the health and environmental impacts of the solvents involved in PSC processing remain a barrier for commercialization and large-scale production. The solvents, some of which are very hazardous, may be released into the atmosphere causing environmental and health impacts, condensed for energy recovery via incineration, which produces carbon emissions, or distilled for solvent recovery, which requires additional infrastructure and energy input. This project will focus on sustainable chemistry and engineering of PSCs via green-solvent and solvent-free approaches. Notably, this project will take an integrated, multidisciplinary approach that considers all key components of a PSC; the light-absorbing perovskite layer, charge-transport layers, and performance-enhancing additives. A novel insitu-transmission characterization technique will be used to provide fundamental insight into the formation of the PSC layers with green solvents. The manufacturing processes will be studied and optimized to minimize harmful solvents and exhaust, and the performance of the PSCs will be studied and collaboratively optimized by the Canadian and German teams to achieve sustainable PSC manufacturing.

钙钛矿太阳能电池（PSC）在过去十年中作为一种令人兴奋的低成本可再生能源技术出现，其将阳光转化为电能的效率现在与硅太阳能电池相当。然而，PSC 加工中涉及的溶剂对健康和环境的影响仍然是商业化和大规模生产的障碍。这些溶剂（其中一些非常危险）可能会释放到大气中，造成环境和健康影响，通过焚烧进行冷凝以进行能源回收，这会产生碳排放，或者通过蒸馏进行溶剂回收，这需要额外的基础设施和能源输入。该项目将重点通过绿色溶剂和无溶剂方法进行 PSC 的可持续化学和工程。值得注意的是，该项目将采用综合的、多学科的方法，考虑 PSC 的所有关键组成部分；光吸收钙钛矿层、电荷传输层和性能增强添加剂。一种新颖的原位传输表征技术将用于提供对绿色溶剂 PSC 层形成的基本见解。加拿大和德国团队将研究和优化制造工艺，以最大限度地减少有害溶剂和废气，并研究和协作优化 PSC 的性能，以实现可持续的 PSC 制造。
