Recently, Dr. Lei Meng Lei from the Key Laboratory of Organic Solids, Institute of Chemistry, Chinese Academy of Sciences, designed and prepared highly efficient organic stacked solar cells, obtained measurements and Certified and obtained the highest record of the efficiency of organic stacked solar cells with an energy conversion efficiency of 14.2%. Solar energy is the most abundant renewable energy available to human beings. Solar cells directly convert solar energy into electrical energy without generating carbon dioxide emissions. Organic photovoltaic materials and devices have become an important object of research and development for new-generation solar cells due to their solution processing, low cost, abundant raw materials, and outstanding advantages that can be prepared into flexible and translucent devices. In organic solar cells, stacking two bulk heterojunction cells with complementary absorption spectra to form a tandem stacked cell structure can effectively utilize a wider range of solar spectrum and reduce the quantum loss of photon energy. This kind of battery structure has been widely used in traditional inorganic solar cells. Considering the unique characteristics of the narrow absorption peak of organic semiconductors, the stacked battery will improve the performance of organic solar cells more effectively. Moreover, NREL marked the new battery on the highest point of the efficiency curve of the organic stacked solar cell, which was recently released to study the best efficiency map of the battery. The researchers said that the device uses a non-fullerene acceptor material that has a wide and strong absorption capability in the near-infrared region, ensuring a more adequate solar spectral absorption while maintaining low energy loss, which is the choice of stacked cell photovoltaic materials And device design provides new ideas.
