Abstract

A pre-sewing strategy involving terminal-selective healing was established in order to sew structural defects and enable scalability of air-fabricated flexible perovskite solar cells. These cells show a champion power conversion efficiency (PCE) of 24.51%, and demonstrate exceptional bending stability. Corresponding minimodules with areas of 4 and 10 cm2 also show impressive PCEs, of 22.68% and 20.53%, respectively.
