As perovskite solar cells (PSCs) approach commercialization, the buried electron-transport interface remains a hidden source of efficiency loss and long-term instability. Now researchers from Dalian Jiaotong University, Dalian University of Technology and CAS Hefei Institutes, led by Prof. Guozhen Liu, Prof. Zhihua Zhang and Prof. Xu Pan, introduce a one-molecule, self-regulated “bilateral anchoring” strategy that turns this buried weakness into a performance booster. Their work, published in Nano-Micro Letters , delivers record efficiencies for both rigid and flexible PSCs while extending device lifetime under real-world stress.

Innovative Design and Features
Applications and Future Outlook
This work establishes squaric acid as a commercially viable, single-component modifier that unites defect passivation, stress management and energy-level tuning—offering a clear pathway toward >25 % stable PSCs on any substrate. Stay tuned for pilot-line results from Prof. Liu, Prof. Zhang and Prof. Pan’s joint laboratories!
