Crafting Hybrid Perovskites for Sustainable Energy Applications

杂化钙钛矿在能量转换和存储方面受到越来越多的关注，因为钙钛矿的应用潜力是由亚晶格中心的阳离子控制的，这与氧(O2)的量、O*-反键和B位过渡金属-O2的共价度有关。通过不同的材料加工路线制备杂化钙钛矿材料提供了通过缺陷化学来实现结构可调谐和修饰其光学、电学和化学性质的机会。因此，本项目旨在开发新的材料加工方法，通过自下而上的合成路线制备具有可裁剪特征的新型二维混杂钙钛矿复合材料。结合使用衍射、显微镜和光谱工具，将确定结构-功能关系。拟议的方法提供了控制和多功能性，以弥合杂化材料发现的差距，同时解决关于可持续无机成分、物理化学性质(即缺陷、结构、物相等)之间的相互作用的公开科学问题。以及它们通过光电化学和电化学效应对同时和增强的个体能量清除的影响。将这些基本见解与受控增长相结合，将使创新的钙钛矿配方的设计成为可能，这些配方可以促进发现和理解用于能源转换和存储等领域的新混合材料。

Hybrid perovskites are gaining increasing attention for energy conversion and storage due to the application potential of perovskites being controlled by cations in sublattice sites which correlates with the amount of oxygen (O2) o*- antibonding and the degree of B-site transition metal-O2 covalency. The fabrication of hybrid perovskites via different materials processing routes offers the opportunity for structural tunability and modification of their optical, electronic, and chemical properties via defect chemistry. Accordingly, this project aims to develop new materials processing methods to produce a new class of two-dimensional hybrid perovskite composites with tailorable features via bottom-up synthetic routes. Using a combination of diffraction, microscopic and spectroscopic tools, structure-function relationships will be determined. The proposed methodology offers control and versatility to bridge the hybrid materials discovery gap while tackling open scientific questions regarding the interplay between sustainable inorganic components, physicochemical properties (i.e., defects, structure, phase, etc.) and their influence on simultaneous and enhanced individual energy scavenging via photoelectrochemical and electrochemical effects. Combining these fundamental insights with controlled growth, will enable the design of innovative perovskite formulations that can facilitate discovery and understanding of new hybrid materials for energy conversion and storage and beyond.
