Dual Passivation and UV Shielding by Bifunctional UV0 Molecule for High-Performance and Stable Perovskite Solar Cells

Key Points

• The introduction of a UV-resistant molecule reduces lattice damage in perovskite solar cells, improving their stability.
• By utilizing 2,4-Dihydroxybenzophenone, the study demonstrates significant reductions in ion migration within the solar cells.
• The application of additive engineering successfully integrates the UV0 molecule into perovskite films to enhance performance.
• These findings highlight the potential of UV0 to significantly enhance the longevity of perovskite solar cells under UV exposure.
