Abstract

The invention discloses a flexible photoelectric detector array and a preparation method thereof. The flexible photoelectric detector array comprises a substrate; a metal circuit comprising an array electrode and is positioned on the substrate; a surface hydrophilicity / hydrophobicity treatment auxiliary layer positioned on the metal circuit and is provided with a hollow region corresponding to theposition of the array electrode, so that the array electrode is exposed; a photosensitive layer located in the hollow area of the surface hydrophilicity / hydrophobicity treatment auxiliary layer and located on the array electrode; and an encapsulation layer on the photosensitive layer and the surface affinity / hydrophobicity processing auxiliary layer. The flexible photoelectric detector array hasgood light response performance, electrical stability and bending resistance, no crosstalk exists between pixel points of each array unit, light response signals can be independently displayed, and the flexible photoelectric detector array can be used for achieving real-time light tracking detection and light imaging.

Description

technical field [0001] The disclosure belongs to the technical field of optical imaging devices and nano new energy, and relates to a flexible photodetector array and a preparation method thereof. Background technique [0002] With the development of the flexible optoelectronics industry, flexible photodetectors have attracted more and more attention due to their applications in optical communications, imaging technology, and environmental monitoring. In practical applications, large-scale integrated flexible photodetector arrays can meet the growing needs of emerging technologies. However, photodetector arrays based on traditional semiconductor materials have poor performance and cannot be integrated on flexible substrates. [0003] The novel perovskite material is a good choice for assembling flexible photodetector arrays due to its outstanding optoelectronic properties. The biggest challenge in the assembly of flexible photodetector arrays based on perovskite materials ...

Problems solved by technology

So far, several methods for synthesizing arrayed perovskite materials have been reported, but there are still many shortcomings: (1) Some traditional synthesis methods, such as: chemical vapor deposition (CVD), vapor phase epitaxy growth, template method, etc. , due to the need for high temperature and special substrates, it is not suitable for the assembly of flexible devices; (2) the synthesis position of large-scale array materials cannot be precisely controlled, which makes device assembly very difficult; (3) the process is complex, and the device assembly process Inevitably affecting the optoelectronic properties of the material

The above problems have greatly limited the assembly and application of flexible photodetector arrays based on perovskite materials.
