Multifunctional Graphdiyne Enables Efficient Perovskite Solar Cells via Anti-Solvent Additive Engineering
Highlights The use of novel nanographdiyne (o-TB-GDY) via anti-solvent additive engineering significantly enhances the nucleation and growth of perovskite crystals, leading to improved film quality, reduced film defects and suppressed non-radiative recombination. o-TB-GDY primarily remains on the su...

| Summary: | Highlights The use of novel nanographdiyne (o-TB-GDY) via anti-solvent additive engineering significantly enhances the nucleation and growth of perovskite crystals, leading to improved film quality, reduced film defects and suppressed non-radiative recombination. o-TB-GDY primarily remains on the surface of the perovskite films after crystallization, where it strongly interacts with the undercoordinated Pb defects for effective passivation. The optimized perovskite solar cells achieve a champion power conversion efficiency of 25.62% (certified as 25.01%) with good stability. |
