Abstract

The invention discloses a photovoltaic nanometer electric generator and a manufacturing method of the photovoltaic nanometer electric generator. The photovoltaic nanometer electric generator comprises a base, a first electrode, a ferroelectric nanometer wire and a second electrode. The first electrode and the second electrode are arranged on the base, and the ferroelectric nanometer wire transversely grows on the portion, between the first electrode and the second electrode, of the base. The manufacturing method of the photovoltaic nanometer electric generator includes the following steps of firstly, manufacturing the base; secondly, arranging the first electrode and the second electrode on the base through sputtering; thirdly, producing the ferroelectric nanometer wire through the wet chemistry method, and then transplanting the ferroelectric nanometer wire array onto the base 1, wherein the two ends of the ferroelectric nanometer wire are located between the first electrode and the second electrode; fourthly, conducting packaging after the photovoltaic nanometer electric generator is tested to be qualified. According to the photovoltaic nanometer electric generator which is powered by sunlight and developed through the method, power can be continuously supplied to nanometer devices for a long time in the aerospace field and other fields, and microminiaturization and nanocrystallization of a propulsion system are facilitated.

Description

technical field [0001] The invention belongs to the technical field of nanogenerators, and in particular relates to a photovoltaic nanogenerator and a manufacturing method thereof. Background technique [0002] As an important high-tech field emerging in the 21st century, nanotechnology is experiencing an unprecedented period of rapid development. On the basis of the preparation of a large number of new nanomaterials, the research on various related nanodevices with special functions is becoming a new driving force for the development of nanotechnology. Since the miniaturization of the system requires the miniaturization of the corresponding energy supply system, the energy supply of a single device is crucial in a complex nanosystem. From the perspective of green, energy saving and environmental protection, the ideal nanoscale power supply device should be a system that does not depend on external charging energy, is non-toxic, does not produce pollution, and can provide c...
