Problems solved by technology

Although many studies based on these metal oxides and nitrides have demonstrated new nanodevices and applications, however, very little work has been devoted to the self-powering of these nanosystems
In particular, we have not found any reports on the design and manufacture of AC nanogenerators that convert light energy into electrical energy

Abstract

The invention discloses a preparation method of an N-P-N-type photoinduction nano alternative-current power generator based on zinc oxide (ZnO) / polyaniline (PANI) / zinc oxide (ZnO). An N-type ZnO nano rod is synthesized in a method that a seed is firstly grown on an Indium Tin Oxide (ITO) substrate and then hydro-thermal reaction is executed, and a P-type PANI nano fiber is synthesized through an inorganic / organic interface method. In the nano alternative-current power generator device, a great amount of electron-hole pairs are produced inside a photosensitive ZnO nano rod after being radiated by ultravoilet ray, the hole is immediately combined with oxygen ions on the surface of the ZnO to generate the oxygen so as to consume a great amount of holes, and the surplus electrons can directionally move along a conducting wire to form current. Therefore, under the situation that no external voltage is applied, the parts containing ZnO at two sides of the device are respectively radiated by the ultravoilet ray, so the alternative-current power in an opposite direction can be generated. A P-N heterojunction plays an important role in controlling the movement direction of the photo-generated electrons in the ZnO / PANI / ZnO device. Due to the adoption of the method, the optical energy can be converted to the electric power.

Description

technical field [0001] The invention belongs to the field of photoelectric functional materials, in particular to a preparation method of a light-induced nanometer alternator for converting light energy into electric energy. Background technique [0002] In 2006, Wang Zhonglin's research group reported a new method to convert nanoscale mechanical energy into electrical energy. This energy conversion occurs through the piezoelectric effect of ZnO nanofiber arrays. This study shows us a Self-powered energy source. In order to improve the energy generation capability, in 2007, the research group drove ZnO nanofibers through ultrasound and obtained continuous current generation, resulting in the birth of a direct current (DC) nanogenerator. These studies provide us with a good example of converting mechanical energy into electrical energy. (Wang, X.D.; Zhou, J.; Song, J.H.; Liu, J.; Xu, N.S.; Wang, Z.L. Nano. Lett. 2006, 6, 2768-2772; Song, J.; Zhou, J.; Wang, Z.L.2006, 6, 1...
