This project aims to develop new electron microscopy techniques that will unambiguously determine the elusive structures of photoactive perovskite compounds under static and operational conditions, while correlating crystal structure with solar cell device performance. Photoactive perovskites are promising photovoltaic materials, however, many are sensitive to air and irradiation. This has impeded a huge international research effort to determine their structure reliably at the atomic scale. With these new techniques applied to leading compounds and devices, it is expected this project will reveal the structural effects controlling electrical properties and device performance and so enable the design of superior perovskite photovoltaics.

该项目旨在开发新的电子显微镜技术，在静态和操作条件下明确确定光活性钙钛矿化合物的难以捉摸的结构，同时将晶体结构与太阳能电池设备性能相关联。光活性钙钛矿材料是一种很有前途的光伏材料，但许多材料对空气和辐射都很敏感。这阻碍了在原子尺度上可靠地确定它们的结构的巨大国际研究努力。随着这些新技术应用于领先化合物和器件，预计该项目将揭示控制电学性能和器件性能的结构效应，从而能够设计出性能优越的钙钛矿型光伏电池。
