The invention discloses a near-infrared organic van der Waals heterojunction photosensitive field effect transistor based on a charge transfer compound and a preparation method of the near-infrared organic van der Waals heterojunction photosensitive field effect transistor. According to the photosensitive field effect transistor, the two-dimensional organic semiconductor and the van der Waals heterojunction are introduced, and the charge transfer compound is formed in the photosensitive layer so that the carrier mobility of a device is improved, a near-infrared absorption peak is generated, and the types of materials of an organic infrared detector are enriched. 本发明公开了一种基于电荷转移复合物的近红外有机范德华异质结光敏场效应晶体管及其制备方法。本发明的光敏场效应晶体管引入二维有机半导体及范德华异质结，并在光敏层中形成电荷转移复合物，以此提高器件载流子迁移率并产生近红外吸收峰，丰富有机红外探测器的材料种类。
