Realizes achievement transformation around the invention patent of flexible perovskite solar cells

• Recently, the launching ceremony of the 2024 Jiangxi Province Intellectual Property Publicity Week was held in Nanchang. Representatives from the polymer and energy chemistry research team of Nanchang University attended the event signing ceremony. Among them, the team of Professor Chen Yiwang from the School of Chemistry and Chemical Engineering of our school realized the transformation of the patented results of flexible perovskite solar cells. 

  
  

  Perovskite photovoltaic power generation is one of the fastest growing, most dynamic and most eye-catching solar application fields in recent years. Its application scope supports the research and development of emerging cutting-edge thin film and flexible battery production process technologies, especially its compatibility with large-scale flexible " The process characteristics of roll-to-roll continuous printing are driving the innovation of photovoltaic power generation technology in the direction of low energy consumption, low cost and flexibility. The main contents of the invention patent transferred this time focus on the excellent semiconductor properties, easy band gap adjustment and wet processability of perovskite materials, through the toughened structural design of polymer elastomer, the synergistic barrier effect of interface molecular chemistry and physics, and the shear-based The wet processing process of the photosensitive layer morphology evolution conversion factor calculated by shear impulse has realized the key technology for the printing and preparation of large-area, high-efficiency perovskite solar cells. The advantage of the patent is that it reduces the efficiency loss of large-area flexible solar cells through polymer elastomers, molecular chemical barrier and physical adhesion packaging structures combined with rheological structure-activity relationships, breaking through the current integrated preparation of flexible thin-film solar cells and components. technical barriers to fill the domestic gaps.

• The transfer of the team's patents aims to transform research results into practical applications. It is the beginning of a systematic project integrating the knowledge chain, innovation chain, and industrial chain. The team makes full use of its resource and technological advantages, adheres to the deep integration of industry, academia, and research, and serves the local economy. For high-quality development, we actively explore new paths for patent transformation and application, so that scientific research and production lines can be effectively "combined" and scientific and technological achievements can "take root and bear fruit".
