An Almost Transparent Image Pixel with a Pentacene/ZnO Photodiode, a Pentacene Thin-Film Transistor, and a 6,13-Pentacenequinone Phosphor Layer



original image

An almost transparent image pixel on glass is demonstrated for the first time under visible and UV illumination at 3 V. The pixel is composed of a pentacene thin-film transistor and a serially connected pentacene/ZnO photodiode, with or without a 6,13-pentacenequinone phosphor layer that was deposited on the photodiode for more efficient light detection.
