Evolution of structure and optoelectronic properties during halide perovskite vapor deposition
Original language description
The efficiency of perovskite-based solar cells has increased dramatically over the past decade to as high as 25%. Vapour deposition is a promising technique that potentially enables the fabrication of perovskite solar cells on large areas. However, to implement a large-scale deposition method, understanding and controlling the specific growth mechanisms are essential for the reproducible fabrication of high-quality layers. Here, we study the structural and optoelectronic kinetics of MAPbI3, employing in-situ PL spectroscopy and GI-SAXS/WAXS simultaneously during perovskite vapour deposition. Such a unique combination of techniques reveals MAPbI3 formation from the early stages and uncovers the morphology, crystallographic structure, and defect density evolution. Furthermore, we show that the nonmonotonous character of PL intensity contrasts with the increasing volume of the perovskite phase during the growth, although bringing valuable information about the presence of defect states.
