The rGO/SnO2 nanoarrays (rGO/SnO 2 NAs) Schottky junction is synthesized by a series of RF magnetron sputtering, hydrothermal and electrochemical deposition. The unique transparent junction exhibits the broadband photoelectric responses from the ultraviolet to visible light. As shown, the proper rGO/SnO 2 NAs display highly transparency of about ~60% and dramatically enhance photoelectric conversion of about ∼100 times than that of the initial Schottky junction. Finally, the mechanism of the Schottky junction is investigated.
