Morphological Stabilization in Organic Solar Cells via a Fluorene-Based Crosslinker for Enhanced Efficiency and Thermal Stability

Autor: Zongwen Ma, Yiman Dong, Yi-Jia Su, Runnan Yu, Huaizhi Gao, Yongshuai Gong, Ze-Ye Lee, Chunhe Yang, Chain-Shu Hsu, Zhan’ao Tan

Publikováno v: ACS applied materialsinterfaces. 14(1)

Power conversion efficiencies (PCEs) and device stability are two key technical factors restricting the commercialization of organic solar cells (OSCs). In the past decades, though the PCEs of OSCs have been significantly enhanced, device instability
