US 2025/0063930 A1 · METHOD FOR MANUFACTURING AN INTRINSICALLY STRETCHABLE ORGANIC SOLAR CELL

Abstract

Provided is a method for manufacturing an intrinsically stretchable organic solar cell, a manufacturing method thereof, and an electronic device comprising the same. The intrinsically stretchable organic solar cell of the present invention is characterized that wherein excellent interfacial bonding among stretchable constituent elements constituting each layer is induced so that the constituent elements are seamlessly integrated into a single system, thereby ensuring excellent initial power conversion efficiency (PCE), and mechanical robustness showing that 70% or more of initial PCE is maintained in spite of repetitive tensile strains. Thus, the organic solar cell is useful for an electronic device applied to any one selected from a group consisting of sensors, electronic skins, flexible displays, and stretchable displays.
