Abstract: A carbazole-based graft copolymer capable of controlling a self-assembled structure and a method of synthesizing the same are provided. Specifically, the copolymer is capable of controlling a self-assembled structure which can control the morphology of a polymer structure and the size of pores by controlling the molecular weights of polylactic acid (PLA) functioning as a coil and of a carbazole copolymer to prepare a poly(carbazole)-coil graft copolymer of Formula 1 below and the method of synthesizing the same is provided. In Formula 1, X represents 0.05 to 0.1, m represents an integer of 7 to 8, and n represents an integer of 56 to 84.

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.
