Tin-based perovskite solar cells achieved efficiencies of 14.03% and 12.44%, marking a performance record.
The introduction of 2D perovskite via organic spacers optimizes crystallization kinetics and improves device stability.
A quasi-epitaxial growth strategy was developed to enhance structural order and charge transport dynamics.
The findings suggest new avenues for high-performance, lead-free perovskite photovoltaics.
