Controlled Crystallization Kinetics via Conjugated Organic Spacers Enables Ordered Epitaxial Growth of Two-Step Deposited Tin-based Perovskite Solar Cells
{{output}}
Tin-based perovskite films typically exhibit random crystal orientations, with significant accumulation of defects acting as charge recombination centers, which severely limit device performance. Furthermore, the disordered two-dimensional (2D) perovskite sign... ...
