Abstract

Methylammonium lead iodide (CH3NH3PbI3) perovskite solar cell in a flexible fiber shape is developed via a fully dipping process with a mixed solvent of N,N-dimethylformamide (DMF) and N-methyl-2-pyrrolidone (NMP) followed by toluene dipping. We introduce the first-ever effective n-type compact layer through facile anodizing of titanium wire, achieving a considerable power conversion efficiency of 3.85%, which remains stable during bending; spray-deposited silver nanowires (Ag NWs) are used as the top electrode instead of gold. The ease of fabrication, low cost of materials, and all-solid-state structures result in a simple approach to developing electronic textiles for harvesting solar energy and blazes a new trail in the field of fiber-shaped photovoltaics.
