Abstract

Inorganic/organic self-powered UV photodetectors based on Zn₂SnO₄/polyaniline (PANI) heterojunction are investigated in this study. Zn₂SnO₄ microspheres were synthesized by the hydrothermal method, and PANI was directly polymerized on Zn₂SnO₄ microspheres to form Zn₂SnO₄/PANI (ZP) compounds. The photodetectors constructed by n-Zn₂SnO₄/p-ZP heterojunction show excellent self-powered behavior with good stability and repeatability under UV light illumination. In particular, the device based on Zn₂SnO₄/ZP-30 displays the high photocurrent (10.805 μA), responsivity (251.279 mA W⁻¹) and detectivity (1.629 × 10¹² Jones) at zero bias. The favorable bandgap difference and structure are contributed to separate and transport photogenerated carriers rapidly and thus enhance its photoresponse performances.

增强Zn2SnO4/聚苯胺异质结的自供电紫外光探测性能

研究了基于Zn2SnO4/聚苯胺（PANI）异质结的无机/有机自供电紫外光电探测器。采用水热法合成了Zn2SnO4微球，并将聚苯胺直接聚合在Zn2SnO4微球上，形成了Zn2SnO4/PANI （ZP）化合物。由n-Zn2SnO4/p-ZP异质结构建的光电探测器在紫外光照射下表现出良好的自供电性能，具有良好的稳定性和重复性。特别是，基于Zn2SnO4/ZP-30的器件在零偏置下具有高光电流（10.805 μA）、响应度（251.279 mA W−1）和探测率（1.629 × 1012 Jones）。良好的带隙差和结构有助于快速分离和传输光生载流子，从而提高其光响应性能。
