Embodiment 1

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

[0027] Step S1, provide an ITO transparent conductive substrate, and clean and pretreat the ITO transparent conductive substrate; the method for cleaning and pretreating the transparent conductive substrate is to put the ITO transparent conductive substrate into glass cleaning agent, acetone, Ultrasonic cleaning was performed in ethanol and isopropanol for 10 minutes each time. After the ultrasonic cleaning was completed, it was placed in an oven at 130°C for 20 minutes for drying, and then treated with ultraviolet and ozone for 10 minutes before use.

[0028]Step S2, prepare the anode buffer layer on the ITO transparent conductive substrate, first adopt the method for spin coating to grow one deck PEDOT:PSS anode buffer layer on the ITO transparent conductive substrate, after the spin coati...

Detectivity and lifetime of hybrid perovskite photodetectors.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to an organic-inorganic hybrid perovskite photodetector and a preparation method thereof. Background technique [0002] Photoelectric detectors are widely used in various aspects of the national economy and military fields. In recent years, organic-inorganic hybrid perovskite photodetectors have attracted extensive attention 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 relatively few reports on photodetectors based on organic-inorganic hybrid perovskites, and there are still a series of problems to be solved in photodetectors based on organic-inorganic hybrid ...
