摘要

柔性过氧化物太阳能电池（PSC）在可穿戴电子设备和航空航天领域的应用前景广阔，因此受到越来越多的关注。然而，柔性 PSC 的效率和稳定性仍然落后于刚性 PSC。在这里，我们使用 N,N-二甲基丙烯酰胺（DMAA）原位合成交联聚合物，用于柔性锡铅混合 PSC。DMAA 可作为支架聚集在晶界处，以调节包晶的结晶并减少缺陷。刚性和柔性锡铅混合 PSC 的效率分别为 16.44% 和 15.44%。此外，柔性锡铅混合 PSCs 还表现出卓越的弯曲耐久性，在半径为 5 毫米的条件下弯曲 5000 次后，其效率仍保持在原来的 80% 以上。

High performance flexible Sn-Pb mixed perovskite solar cells enabled by a crosslinking additive

Flexible perovskite solar cells (PSCs) have drawn increasing attention due to their promising applications for wearable electronics and aerospace applications. However, the efficiency and stability of flexible PSCs still lag behind their rigid counterparts. Here, we use N,N-dimethyl acrylamide (DMAA) to in situ synthesize cross-linking polymer for flexible Sn–Pb mixed PSCs. DMAA can gather at grain boundary as a scaffold to regulate the crystallization of perovskite and reduce defects. The rigid and flexible Sn–Pb mixed PSCs showed efficiencies of 16.44% and 15.44%, respectively. In addition, the flexible Sn–Pb mixed PSCs demonstrated excellent bending durability, which retained over 80% of the original efficiency after 5000 bending cycles at a radius of 5 mm.
