Supramolecular Stabilization of Wide-Bandgap Perovskites Enables Durable Perovskite-Organic Tandem Solar Cells.
Perovskite-organic tandem solar cells (PO-TSCs) offer a compelling platform for flexible photovoltaics by combining wide-bandgap (WBG) perovskite top cells with mechanically compliant organic rear cells. However, their long-term stability is critically limited by the intrinsic instability of WBG mixed-halide perovskite...
