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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
