摘要

Organic-inorganic hybrid heterojunctions are ever so promising for low-cost and high-efficient photoelectric devices. We report a p-n junction diode composed of inorganic ZnO nanowire arrays (ZNAs) and organic 2, 2', 7, 7'-tetrakis-(N, N-di-p-methoxyphenylamine)-9, 9'-spirobifluorene (spiro-MeOTAD). A maximum photo-responsivity of 1.32 mA/W is observed under illumination at zero bias. We also demonstrate that the photo-current time response is observed to be rapid, consistent, as well as repeatable. On blue light weak irradiance (410 nm, 75 mu W/cm(2)), the rise time constant and decay time constant were found to be 0.12 and 0.06 s, respectively. These results suggest ZNAs/spiro-MeOTAD heterojunction as a candidate for an efficient self-powered blue light detector. (C)2019 Optical Society of America
