Abstract

The invention discloses an alcohol-soluble molybdenum oxide interface layer material synthesis method and application. Metal molybdenum powder serves as the raw material, hydrogen peroxide serves as oxidant, organic acid is adopted as stabilizer and cosolvent, alcohol serves as a proton donor, and synthesized molybdenum oxide powder is of an amorphous structure. The invention further discloses an organic solar cell device with alcohol-soluble molybdenum oxide as an interface layer. Molybdenum oxide synthesized through the method is good in alcohol solubility and film forming performance, can evenly form a film on a transparent electrode and an organic active layer, can achieve low-temperature processing and is compatible with a flexible substrate. A molybdenum oxide modified anode interface layer can effectively achieve cavitation extraction, and greatly improves photoelectric efficiency of devices. Meanwhile, the stable material overcomes instability of electrode interfaces and organic layer interfaces to a certain extent, and accordingly stability of organic solar cells is improved.

Description

technical field [0001] The invention belongs to the field of organic solar cells, and in particular relates to a synthesis method and application of an alcohol-soluble molybdenum oxide interface layer material. Background technique [0002] Energy issues are major issues that affect human survival and sustainable development. Traditional fossil energy is the main body of energy supply at present, but it is a non-renewable resource and has been gradually exhausted. At the same time, fossil burning has caused serious environmental problems, posing a serious threat to human living environment and health. Due to its huge energy storage, solar cells are clean and renewable resources, and are widely accepted by humans and considered to be the best alternatives to fossil energy. As we all know, the most common form of energy use is electrical energy, and the conversion of solar energy into electrical energy plays a key role in the large-scale application of solar energy. Therefo...
