Semitransparent indium-tin-oxide-free non-fullerene organic photodetectors with double-side ultraviolet selective responses

摘要

Visibly transparent organic photodetectors have drawn lots of attention for low-cost processing, mechanical flexibility or wavelength selectivity to be utilized in various fields including private households and industrial & military application. They can be fabricated by combining transparent conductive electrodes with desired transmission window and organic donor & acceptor composites with selective absorption range outside the visible wavelength. Here, we demonstrate an indium-tin-oxide-free, fullerene-free, ultraviolet detective, visibly transparent organic photodetector with an average visible transmittance of 46.7% and a similar-spectral, double-side responsivity to the ultraviolet light. At a wavelength of 350 nm and under -10 V, the specific detectivity can be 10(10) Jones. (C) 2018 Elsevier B.V. All rights reserved.
