Disclosing the guidelines and constitutive relationships for highly efficient and stable ternary organic photovoltaic cells paves the way for their commercialization
Solid additive modulation to enhance morphology quality for the preparation of high-efficiency, high-stability, low-cost oligothiophene photovoltaic cells
Recently, Lu Shirong’s team from the School of Materials Science and Engineering, together with Hong Kong Polytechnic University and King Abdullah University of Science and Technology, has made a series of breakthroughs in the field of organic solar cells based on the innovation of photovoltaic material structure and cell device process. The related research results have been published as corresponding author in Energy & Environmental Science (2023, IF: 39.714), Advanced Functional Materials (2022) and other international journals.
Printable organic solar cells resemble a piece of plastic film that can generate electricity, with the advantages of lightness, thinness, flexibility, and good low-light performance. The research team focused on this area and achieved the following breakthroughs: 1) designed and developed a high-performance ternary polymer outdoor organic solar cell with cell efficiency up to 18%, and can continue to maintain 96% of the initial efficiency after 32 days of exposure to air; 2) developed a new solid additive, which can significantly improve the quality of active layer morphology, and successfully increased the efficiency of oligothiophene-based organic solar cells to 16%, setting a new world record for related cell efficiency, and certified by a third-party authoritative structure.
Achieving the “double carbon” goal is a broad and profound change. The new energy sector is facing new challenges as well. There is an urgent need to develop a new generation of flexible photovoltaic technology adapted to the distributed photovoltaic power generation field, which can be used to compensate for the application limitations of crystalline silicon solar cells. Printable organic solar cells can meet this demand, and the future market prospects are promising.
