Problems solved by technology

However, the distance between the driving electrode and the zinc oxide nanowire needs to be precisely controlled, and a small amount of error will cause the generator to not work normally; the free end and the driving electrode must be in constant contact and friction during operation, which may cause wear and tear on the nanowire and the electrode. And then affect the performance and life of the nanogenerator

Abstract

The invention relates to the technical field of green energy obtaining, and discloses a DC generator based on a moving Schottky junction, the DC generator is composed of a semiconductor substrate layer and a conductive thin film layer. A preparation method includes the following steps: a first electrode is manufactured on the back of a semiconductor substrate material. And then a second electrodeis manufactured on a flexible conductive film material; then the flexible conductive thin film material is laminated on the surface of the semiconductor substrate and moved to be in contact with eachother so as to obtain the DC generator based on a moving Schottky heterojunction, and the DC signal can be obtained by movement relative to each other. The generator based on the moving Schottky junction of the invention utilizes the drift charge of the Schottky junction region to be directionally separated under a built-in electric field, and can convert the external mechanical energy into directcurrent, thereby providing a renewable green clean energy for various electronic equipment. Piezoelectric materials are not needed, and the device structure and process are simple.

Description

technical field [0001] The invention relates to a direct current generator based on a mobile Schottky junction and a preparation method thereof, belonging to the technical field of energy acquisition devices. Background technique [0002] With the rapid development of electronic devices, people's demand for energy, especially portable energy, is increasing. Common lithium batteries can provide energy for these electronic devices, but there are problems of limited capacity and environmental pollution. Correspondingly, it cannot meet the applications in some special extreme environments. In recent years, nanogenerators, as an important new green energy device, have attracted extensive attention from research and industry. It can convert green energy such as mechanical energy and tidal energy in nature into electrical output, so as to provide renewable green and clean energy for various electronic devices, and can alleviate the energy crisis to a large extent without environm...
