The invention discloses an organic photoelectric detector based on an optical microcavity effect and a preparation method thereof, belonging to the field of photoelectric detection devices. The photodetectors are sequentially arranged from bottom to top as follows: a glass substrate, a semi-transparent conductive electrode layer, a double narrow-band modulation layer, an organic functional layer, a hole transport layer, and a metal electrode layer. The optical microcavity structure formed by the semi-transparent conductive electrode layer, the double narrowband modulation layer, the organic functional layer, the hole transport layer and the metal electrode layer can realize the double narrowband response to different wavelength bands, so as to have the dual band narrowband detection capability. . The invention effectively solves the problems that the organic photoelectric detector has a large half-wave peak width, poor detection performance in the near-infrared band and only has a single-band detection capability. |
