Organic small molecule modifies the perovskite layer to prepare efficient and stable inverted perovskite solar cells.
The perovskite layer is the core component of perovskite solar cells (PSCs), and the quality of the perovskite film critically impacts the performance of PSCs. Interfacial contact optimization, defect passivation, and energy level alignment regulation are effective approaches to fabricate high-performance PSCs. Herein,...
