Preparationof fabric-like transparent electrodefor flexible perovskite solar cell

•A flexible and transparent fabric-like electrode was fabricated.•The electrode has excellent light transmission and mechanical stability.•The electrode based perovskite solar cellshave well flexibility and stability. Flexible transparent electrode is an irreplaceable part of flexible solar cells. The polyurethane/polyacrylonitrile nanofibers film loaded with silver nanowire network was fabricated and served as a transparent fabric-like electrode. This fabric-like transparent electrode shows promising flexibility and well stretchability. It possesses a light transmission of 80% in the visible range, and its bending radius is less than one millimeter with a break strain of 70%. This transparent fabric-like electrode retains its original charge transport property during being appropriately stretched and bent. Hence, the electrode was employed to assemble perovskite solar cells. As a result, a 4.06% conversion efficiency was obtained. More importantly, the devices maintained above 85% its original efficiency under the bending radius of 3 millimeter.
