Embodiment 1

[0026] A preparation method of an organic-inorganic hybrid perovskite photodetector, and the preparation of the organic-inorganic hybrid perovskite photodetector comprises the following steps:

[0027] In step S1, an ITO transparent conductive substrate is provided, and the ITO transparent conductive substrate is cleaned and pretreated; the method for cleaning and pretreatment of the transparent conductive substrate is to put the ITO transparent conductive substrate into glass cleaning agent, acetone, Ultrasonic cleaning was carried out in ethanol and isopropanol for 10 minutes each time. After the ultrasonic wave was completed, it was placed in an oven at 130° C. for 20 minutes for drying, and then treated with ultraviolet ozone for 10 minutes before use.

[0028]Step S2, prepare the anode buffer layer on the ITO transparent conductive substrate, firstly adopt the method of spin coating to grow a layer of PEDOT:PSS anode buffer layer on the ITO transparent conductive substrate...

Abstract

The invention belongs to the technical field of photoelectric detection, and specifically relates to an organic and inorganic hybrid perovskite photoelectric detector and a preparation method thereof.According to the organic and inorganic hybrid perovskite photoelectric detector and the preparation method thereof, CH3NH3I after coating for three times is regarded as an induction layer for growthof an organic and inorganic hybrid perovskite light-sensitive layer, a precursor solution for growth of the organic and inorganic hybrid perovskite light-sensitive layer is improved, the method of theannealing process is improved, and the detection rate and the lifetime of the organic and inorganic hybrid perovskite photoelectric detector are greatly increased and prolonged.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to an organic-inorganic hybrid perovskite photoelectric detector and a preparation method thereof. Background technique [0002] Photodetectors are widely used in various aspects of the national economy and military fields. In recent years, organic-inorganic hybrid perovskite photodetectors have received extensive attention in recent years due to their outstanding advantages such as simple preparation methods, low cost, light weight, and the ability to be fabricated into flexible devices. Organic-inorganic hybrid perovskite materials have a series of advantages, and important research progress has been made in organic-inorganic hybrid perovskite solar cells in recent years. There are still few reports on photodetectors based on organic-inorganic hybrid perovskites, and there are still a series of problems to be solved for photodetectors based on organic-inorganic hy...
