磁感應的自供電可撓式有機光電晶體

Abstract

在此我們報告一種嶄新的可撓式的磁控光電晶體是一種藉由結合有機異質接面太陽能電池(ITO/ZnO/P3HT:PC61BM/MoO3/Ag)和具有為金字塔結構的磁電薄膜元件(FeNi/PDMS/AgNWs)的垂直整合結構。在此我們利用兩種元件分別感應光和磁場的特性來集結形成電晶體。這項器件可作為開關使用，而且透過光和磁訊號可以調控流經電晶體的訊號。這份研究裡的光電晶體具有一些特性，包含快速響應時間、低成本、自供電、高開關電流比率、非接觸式人機互動和低耗能。這些獨特的特性使磁控光電晶體有著發展穿戴式電子元件、監控系統、通訊和資訊安全的潛力。

We report a novel flexible magnetically controllable phototransistor using a tandem structure composed of an organic solar cell (OSC) of ITO/ZnO/P3HT:PC61BM/MoO3/Ag and a magnetoelectronic film with micropyramid structure of FeNi/PDMS/AgNWs. This novel device carries the properties of these two components sensing light and magnetic field, to form a transistor. It can function as a switch, i.e., current flowing through the transistor can be modulated by optical and magnetical stimuli. Further, the novel phototransistor has several features, including fast response time, low-cost, self-powered, high ON/OFF ratio, touchless human–machine interaction, and low power consumption. These unique characteristics drive the magnetically controllable phototransistor a potential candidate in wearable electronics, monitors, communication, and information security.
