该项目旨在提高用于先进光电应用的金属卤化物钙钛矿能源材料的固有稳定性。关键概念是通过间隙管理抑制合金化钙钛矿的相分离，以及通过中间相演变的合理设计开发非合金化钙钛矿的低温结晶，这有可能在解决钙钛矿器件操作稳定性的关键挑战方面产生新的知识。预计这些成果将提供有价值的知识产权，以加速钙钛矿技术的商业化，从而实现太阳能的低成本利用，实现可持续和低碳排放的经济。

This project aims to improve the intrinsic stability of metal halide perovskite energy materials for advanced optoelectronic applications. The key concept is to suppress the phase-segregation for alloyed perovskite by interstitial management as well as develop low-temperature crystallization for non-alloyed perovskite through rational design of the intermediate phase evolution, which has the potential to generate new knowledge in addressing the key challenge on the operational stability of perovskite devices. The outcomes are expected to deliver valuable intellectual property to accelerate the commercialization of perovskite technology, enabling low-cost utilization of solar energy for a sustainable and low carbon-emission economy.
