Abstract

The invention relates to the technical field of thin film preparation, in particular to a germanium selenide thin film and a preparation method thereof. The germanium selenide thin film is deposited on an ITO substrate through an electrochemical method. According to the preparation method of the germanium selenide thin film, the germanium selenide thin film is deposited on the conductive side faceof ITO, specifically, GeSe powder is put into an ethanol solution or an acetone solution, and thus a dark brown suspension is formed; and then, starch is added into centrifugal supernatant of the suspension, a power source is switched on, a reaction is conducted, and thus the germanium selenide thin film is obtained. By adopting the preparation method, simpleness is achieved, and the germanium selenide thin film capable of expanding germanium selenide application can be prepared.

Description

technical field

[0001] The invention relates to the technical field of thin film preparation, in particular to a germanium selenide thin film and a preparation method thereof. Background technique

[0002] Many semiconductor materials, such as titanium oxide, cuprous oxide, bismuth iodide oxide, etc., have no response in the near-infrared region because of their large band gaps. Devices made of a single semiconductor material can only produce photoelectricity in the visible region. or images. In response to this problem, Saxena et al. proposed the idea of ​​using the up-conversion optical properties of rare earth ion doping to convert near-infrared light into visible light and then be absorbed by semiconductor materials.

[0003] So far, the research around this idea has focused on placing the prepared up-conversion nanomaterials on the back substrate of amorphous silicon solar cells, or adding them to the inside of sensitized solar cells, or combining them with organic sol...
