Professor Chen Yongsheng of the School of Chemistry, Nanchang University, has made significant progress in the field of organic photovoltaics. The latest results were published on the November 24th issue of Nature-Photonics (Nature-Photonics), an internationally renowned academic journal, with an impact factor of 29.958. And achieved a 9.3% single device photovoltaic efficiency. Organic photovoltaic technology is a promising green energy technology and has significant application prospects and social benefits. Among them, electron donor materials based on organic solution-processable (oligomerized) small molecules have advantages of structural determination, easy purification, high structural diversity and easy control, and high charge mobility, and are important organic photovoltaic donor materials. In recent years, Professor Chen Yongsheng team designed and synthesized a series of organic (oligomeric) small molecule electronic donor materials, and achieved a series of important results. The previous results have been published in the JACS and other related papers. . Based on this, they designed a new type of donor material, and through optimization of components and components, achieved the highest single-cell photovoltaic efficiency in the field of small molecule photovoltaics, and the photoelectric conversion process, mechanism, and The step-by-step efficiency has a more comprehensive understanding of the future development of this field and has an important guiding significance for higher efficiency photovoltaic devices. This work has received strong support from the Ministry of Science and Technology's "973" and "great research program" and the fund committee and other projects, and has cooperated with a number of research institutes at home and abroad.
