Interfacial instability is a critical constraint for the practical deployment of perovskite solar cells (PSCs), which commonly arises from the metastable residual PbI 2 and deep-level defects like under-coordinated Pb 2+ . Herein, a benzeneseleninic acid (PSA)-enabled interfacial chemical reconstruction strategy, tha...

Perovskite solar cells (PSCs) have attracted widespread attention from researchers worldwide and experienced rapid development in recent years. The bottom interface plays a crucial role in charge transfer and collection, and its status significantly affect the perovskite crystallization and the performance of PSCs....

Wide-bandgap (WBG) perovskites are essential for all-perovskite tandem solar cells, but their performance remains limited by defect-assisted nonradiative recombination, halide segregation, and residual lattice strain. Here, we develop a dimensional seed-guided strategy to regulate the crystallization pathway and stra...
