摘要
Research on solution-processed lead-halide perovskites is on the rise due to their highly anticipated applications as photonic devices. These perovskites exhibit strong band-to-band luminescence even at room temperature, resulting in high energy-conversion efficiencies for solar cells and light-emitting diodes. Here we summarize recent optical spectroscopic studies on CH3NH3PbI3 and CH3NH3PbBr3 perovskite single crystals, thin films, and diode devices along with a discussion on their carrier generation, recombination, and transport dynamics in relation to the inherent efficient conversion between light and electricity.
