High-performance triboelectric nanogenerators based on the organic semiconductor copper phthalocyanine

Abstract

compared to those reported for inorganic semiconductor-based TENGs. Leveraging the ethanol sensitivity of CuPc, a self-powered ethanol sensor was also demonstrated. The successful demonstration of organic semiconductors as the triboelectric friction layer will enable the development of fully flexible high performance semiconductor-based TENGs, as well as direct current TENGs based on semiconducting heterojunctions.
