Lead halide perovskites are currently considered as one the most promising materials for novel, thin-film solar cells. These cells are made using cheap materials and technologies, and their efficiency currently exceeds 25%, which is close to the efficiency of conventional inorganic Si-based devices. Therefore, they are very attractive candidates to replace inorganic solar cells and hold great promise for stimulating a breakthrough in the development of renewable energetics. Metalorganic perovskites are also perspective materials for other optoelectrical devices, such as light-emitting diodes or photodetectors. However, despite the spectacular advance during recent years in increasing the performance of the perovskite-based optoelectronic devices, their long-term stability and lead toxicity are the main crucial problems obstructing their practical applications. To improve the stability of perovskite solar cells and replace toxic materials with environmentally friendly ones, our primary goal is to understand the fundamental processes limiting the performance of the solar cells and light-emitting diodes, and then find the possible ways to improve the material quality.
