Abstract：

Some recent progress on theoretically investigating the intrinsic correlation between the macroscopic physical properties and microstructure, proposing underlying micro-physical mechanisms, and designing novel hybrid halide perovskites for photovoltaic applications. In this talk, I will present the deep-seated reasons for the external pressure-driven nonmonotonic bandgap evolution of cubic phase MAPbl3 at the theoretical level, and the revealed mechanism is verified to be universally applicable to different crystal phases. Moreover, I will briefly introduce recent progress in theoretical research on low-dimensional hybrid halide perovskites which are expected to overcome the obstacles of poor stability of hybrid perovskite materials for photovoltaic applications.
