Low-Temperature Photocrystallization of Atomic Layer Deposition-Processed Tin Oxide for Highly Efficient and Flexible Perovskite Solar Cells.

ABSTRACT: Atomic layer deposition (ALD) enables an excellent surface coverage and uniformity in the preparation of large-area metal-oxide thin films. In particular, ALD-processed SnO₂ has demonstrated great potential as an electron transport layer in flexible perovskite solar cells (PSCs) and tandem modules. However, the poor electrical conductivities and surface wettabilities of amorphous SnO₂ remain critical challenges for commercialization. In this study, a low-temperature and rapid crystallization process for amorphous SnO₂ is introduced, based on the use of high-power ultraviolet (UV) exposure (UV-SnO₂) to achieve high-performance flexible PSCs. The generation of highly dense O₃/OH radicals under UV exposure effectively ruptures the imperfe
