Dramatic advances in perovskite solar cells (PSCs) and the blossoming of wearable electronics have triggered tremendous demands for flexible solar-power sources. However, the fracturing of functional crystalline films and transmittance wastage from flexible substrates are critical challenges to approaching the high-performance PSCs with flexural endurance. In this work, a nanocellular scaffold is introduced to architect a mechanics buffer layer and optics resonant cavity. The nanocellular scaffold releases mechanical stresses during flexural experiences and significantly improves the crystalline quality of the perovskite films. The nanocellular optics resonant cavity optimizes light harvesting and charge transportation of devices. More importantly, these flexible PSCs, which demonstrate excellent performance and mechanical stability, are practically fabricated in modules as a wearable solar-power source. A power conversion efficiency of 12.32% for a flexible large-scale device (polyethylene terephthalate substrate, indium tin oxide-free, 1.01 cm2) is achieved. This ingenious flexible structure will enable a new approach for development of wearable electronics. A nanocellular scaffold is introduced to construct a mechanics buffer layer and optics resonant cavity in a flexible perovskite solar cell. A power conversion efficiency of 12.32% is achieved with a flexible, large-scale device (polyethylene terephthalate substrate, indium tin oxide-free, 1.01 cm2). Moreover, the devices, which demonstrate excellent performance and mechanical stability, are practically fabricated in modules for a wearable solar-power source.
