The development of self-assembled molecules (SAM) is crucial for enhancing the performance of PSCs [2]. Group 1: Research Breakthroughs - A significant breakthrough was achieved in the design of new organic self-assembled molecules, resulting in the first development of a highly efficient, stable, and well-dispersed self-assembled molecular material with dual radical characteristics [2][5]. - The research team successfully designed a dual radical self-assembled monolayer to facilitate hole transport within the monolayer [4]. Group 2: Performance Metrics - The small-area devices based on the new material achieved a power conversion efficiency of 26.3%, while micro-modules (10.05 cm²) reached an efficiency of 23.6%. The perovskite-silicon tandem cells (1 cm²) exceeded 34.2% efficiency, certified by the National Renewable Energy Laboratory (NREL) [7]. - The developed materials and devices exhibited excellent stability, maintaining over 97% performance retention after 2000 hours of operation at 45°C, significantly surpassing traditional materials and devices [8]. Group 3: Implications for Industry - This research provides a new molecular design paradigm to address the conductivity, stability, and large-area processing challenges in perovskite solar cells, injecting core driving forces for the industrialization of next-generation efficient and stable photovoltaic components [8].
