Problems solved by technology

However, there are few reports on self-powered UV detectors, and this type of detectors generally have electrolytes that are volatile and hinder the long-term continuous operation of the detectors.
In particular, it should be pointed out that quasi-solid-state self-powered ZnO-based UV detectors based on photochemical cell structures on flexible substrates have not yet been reported.

Abstract

The invention discloses an ionic-liquid-gel-electrolyte-based quasi-solid flexible self-powered ZnO-based ultraviolet detector comprising a transparent conductive flexible substrate, a ZnO seed crystal layer, a ZnO nano array, an ionic liquid gel electrolyte layer, a Pt conductive layer and a flexible substrate. The edge of the detector is sealed by a sealant. According to a preparation method for the detector, a ZnO seed crystal layer grows on a transparent conductive flexible substrate and then a ZnO nano array grows; the ZnO nano array layer is coated with an ionic liquid gel electrolyte; a Pt conductive layer is plated on another flexible substrate; and after binding and sealing, the detector is obtained. Compared with the traditional ultraviolet detector, the provided detector has advantages of not needing an external bias voltage, being carried conveniently, having fast speed, and being capable of bent for usage; and the preparation process is simple and large-area batch production can be realized. Besides, the detector can work stably and continuously without the need to replace an electrolyte frequently.
