Room-temperature fabrication of multi-deformable perovskite solar cells made in a three-dimensional gel framework

Abstract

Application-specific requirements for future perovskite solar cells (PSCs) include being lightweight, having mechanical resilience, and deformability for multi-purpose utilizations ranging from electronic skins and implants in the body to wearable textiles. In the current work, multi-deformable PSCs were made by imbibing solutions with polyaniline, solvothermal-processed (L-Lys)_0.038(CH₃NH₃)_0.962PbI₃ precursor and electron-transporting PCBM in the 3D framework of an amphiphilic PAA–PEG gel matrix. Subsequently, after the solvent removal steps, PSCs with enhanced cell efficiencies and excellent durability under repeated deformations and moisture attack are yielded.
