Recently, the sub-journalsofNature, Nature EnergyandNature Communications, published research results of organic photovoltaic cells obtained by Professor Wang Tao from theInternational School of Materials Science and EngineeringofWUT.

Professor Wang Tao’s research group focused on the research of organic semiconductor molecular aggregates and photoelectric devices, developed the physicochemical methodsto regulate organic semiconductor molecular multistage aggregates, revealed the structure-activity relationship between them and the photoelectric conversion process, and improved the photoelectric conversion efficiency of photovoltaic devices. Their recent research results, titled “Donor-acceptor mutually diluted heterojunctions for layer-by-layer fabrication of high-performance organic solar cells” and “Electronic force promoted intermolecular stacking of polymer donors toward 19.4% efficiency binary organic solar cells”, were published in Nature Energy and Nature Communications. The two studies revealed the diluted heterojunctions formed by P-type and N-type organic semiconductor molecules and the significant enhancementofthe order of photovoltaic molecular aggregates causedbythe electronic force between P-type macromolecules and N-type small molecules. Theseresultshelpedto improve the light absorption and charge transport performance and realize the preparation of high-performance organic solar cells. The efficiency of binary organic solar cells certified by third-party authorities reached 19.06%. Wang Liang, a PhD student, and Gan Zirui, a postgraduate student, are the first authors of the papers respectively. WUT is the sole corresponding unit, and Professor Wang is the sole corresponding author.

It is reported that the other three research results of Professor Wang in this field have been published inAdvanced Materials.
