China Education Equipment Procurement Network News: According to a recent report from the American Physicists Organization Network, in the world of solar energy, organic photovoltaic solar cells have a wide range of potential applications. Researchers at the University of California, Los Angeles and their counterparts from China and Japan used gold nanoparticles in organic photovoltaic solar cells to help them enhance their light absorption capabilities and greatly improve the photoelectric conversion rate of the battery. In the recently published "Nano" magazine of the American Chemical Society, a research team led by Yang Yang, a professor of materials and engineering at the Henry Samueli School of Engineering and Applied Sciences at the University of California, Los Angeles, published an article describing how they used The layer is implanted into two light absorption regions of a series-connected polymer solar cell to form a battery with a special sandwich structure, thereby harvesting light energy with a wider solar spectrum. Yang Yang, the person in charge of the study, Zhang Xingwang from the Key Laboratory of Semiconductor Materials Science of the Institute of Semiconductors, Chinese Academy of Sciences, and Hong Ziruo from Yamagata University ’s Graduate School of Science and Engineering found that the interconnection of gold nanoparticle layers greatly Improve the photoelectric conversion rate of photovoltaic solar cells. The gold nanoparticles can generate a strong electromagnetic field in the thin organic photoelectric layer through the plasma effect. The result is that the light energy is concentrated so that it is more captured by the light absorption region in the battery. Although there are many difficulties in incorporating metal nanostructures into the structure of photovoltaic solar cells, the research team solved these problems and announced for the first time the successful development of plasma-enhanced polymer tandem solar cells. Both experimental and theoretical results show that the improvement of the efficiency of solar photovoltaic cells is due to the enhancement of the near-area of ​​gold nanoparticles, which also shows that the plasma effect has great potential for the development of polymer solar cells in the future. The research team believes that the sandwich structure can be applied to a variety of polymer materials as an open platform, creating opportunities for obtaining highly efficient multilayer tandem solar cells.
