Crafting Hybrid Perovskites for Sustainable Energy Applications

由于钙钛矿的应用潜力受亚晶格位点中的阳离子控制，其与氧（O2）O*-反键的量和B-位点过渡金属-O2共价的程度相关，因此杂化钙钛矿在能量转换和储存方面获得越来越多的关注。通过不同的材料加工路线制造混合钙钛矿提供了通过缺陷化学进行结构可调性和光学、电子和化学性质改性的机会。因此，该项目旨在开发新的材料加工方法，以通过自下而上的合成路线生产具有可定制特征的新型二维混合钙钛矿复合材料。使用衍射，显微镜和光谱工具的组合，结构-功能关系将被确定。所提出的方法提供了控制和多功能性，以弥合混合材料发现的差距，同时解决关于可持续无机组分、物理化学性质（即，缺陷、结构、相位等）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生长相结合，将能够设计出创新的钙钛矿配方，从而有助于发现和理解用于能量转换和存储等的新型混合材料。

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.
