Abstract
Organic-inorganic hybrid perovskites have demonstrated tremendous potential for next-generation electronic and optoelectronic devices due to their remarkable carrier dynamics. Current studies are focusing on polycrystals since the controlled growth of high-quality single crystals is extremely challenging. Here I will discuss the first chemical epitaxial growth of single-crystal hybrid halide perovskites with controlled locations, morphologies, and orientations, using combined strategies of advanced microfabrication and low-temperature solution method. By controlling the lattice mismatch between the substrate and epilayer, strain magnitude and a wide range of functional properties can be readily tuned. This approach opens up broad opportunities for hybrid halide perovskite materials based high performance electronic and optoelectronic devices. A single crystalline hybrid halide perovskite-based solar cell with enhanced photoconversion efficiency is demonstrated.
