Abstract

The invention relates to the field of solar energy, and in particular relates to a photovoltaic material containing a thiophene ring and a preparation method of the photovoltaic material. The organicphotovoltaic material prepared by the method structurally contains the thiophene ring, the thiophene ring has a five-membered ring structure, conforms to a Huckel rule, and has a moderate energy bandgap, wider spectral response, and better thermal stability and environmental stability, so that the organic photoelectric material has excellent photoelectric properties, high conversion efficiency and low manufacturing costs, and is superior to a current common OLED. The invention also provides the preparation method of the organic photoelectric material. The preparation method is simple and haseasily-available raw materials, and can meet the needs of industrial development; the organic photoelectric material provided by the invention has a good application effect in an OLED, and good industrial prospects; and the entire molecule of the product provided by the invention is asymmetric, so that the crystallinity of the molecule is destroyed, the intermolecular aggregation effect is avoided, the product has good film forming performance, and the thermal stability, glass transition temperature and decomposition temperature of the material are improved.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a photoelectric material containing a thiophene ring and a preparation method thereof. Background technique [0002] Today's world economy is mainly based on fossil energy, such as coal, oil and natural gas, etc. However, these non-renewable fossil energy are constantly being exhausted. Since the beginning of the 21st century, global energy issues and the ensuing environmental pollution and climate warming have become increasingly prominent and gradually intensified. Since solar energy has the outstanding advantages of widespread and vast distribution, large amount of resources, no pollution, cleanliness, safety, and easy access, it is considered to be one of the most promising renewable energy sources. Has attracted people's attention. [0003] Due to the limited source of inorganic optoelectronic materials, high price, complicated preparation process, and high cost, more and more ...
