Cathodoluminescence for understanding perovskite solar cells

卤化物钙钛矿太阳能电池（PSC）最近已经成为世界各地光伏（PV）研究的前沿，其认证效率超过了其他已建立的PV技术。然而，PSC技术仍然存在一些挑战，需要解决长期稳定性和商业部署。解决这些问题的一种方法是通过基于对钙钛矿吸收剂材料的结构、化学和光电性质之间相互作用的详细理解来制定明智的策略。阴极发光显微镜是一种功能强大且成熟的技术，能够提供详细的信息，可用于优化和提高效率和长期设备稳定性。在拟议的博士学位中，阴极发光显微镜将用于了解和提高钙钛矿吸收剂材料和器件的长期稳定性。

Halide perovskite solar cells (PSCs) have recently come to the forefront of photovoltaic (PV) research all over the world with the certified efficiencies surpassing the other established PV technologies. The PSCs technology however has still some challenges that needs to be addressed for long term stability and commercial deployments. One way to address these is via development of informed strategies based on detailed understanding of interplay between structure, chemistry and optoelectronic properties of the perovskite absorber materials. Cathodoluminescence microscopy is a powerful and well established technique that is capable of giving this detailed information that could be explored for optimising and increasing efficiency and long-term device stability. In the proposed PhD, Cathodoluminescence microscopy will be utilized to understand and improve the long term stability of the perovskite absorber materials and devices.
