Cathodoluminescence for understanding perovskite solar cells

卤化物钙钛矿太阳能电池(PSCs)最近走到了世界各地光伏(PV)研究的前沿，其认证效率超过了其他成熟的光伏技术。然而，PSCS技术仍有一些挑战需要解决，以实现长期稳定和商业部署。解决这些问题的一种方法是在详细了解钙钛矿型吸收材料的结构、化学和光电性能之间相互作用的基础上，制定知情的策略。阴极发光显微镜是一种强大而成熟的技术，它能够提供这些详细的信息，可以探索这些信息来优化和提高效率和设备的长期稳定性。在拟议的PHD中，将利用阴极发光显微镜来了解和提高钙钛矿型吸收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.
