This project aims to develop a library of novel and two-dimensional Ruddlesden−Popper phases layered perovskites with controlled architecture and tunable bandgaps for high-performance energy harvesting applications. The as-synthesized perovskites are highly crystalline and sandwiched with staggered organic and inorganic layers, which are compatible with layer-by-layer manner to build vertical heterostructure, satisfying the premise of a solar cell with both high power conversion efficiency and low-cost. Apart from springing out a series of high impact publications and patents, a few of these demonstrations have a great potential to be substituted for fossil fuels which will help address clean energy generation and environmental problems.
