Abstract

Wearable double-twisted fibrous perovskite solar cells are developed based on flexible carbon nanotube fiber electrodes, which exhibit a maximum power conversion efficiency of 3.03% and bending stability larger than 1000 cycles, and maintain 89% efficiency after 96 h in ambient conditions if sealed by a transparent polymer layer. The obtained superior performance can shed light on future self-powering e-textiles.
