研究目的
To investigate the synthesis and photovoltaic properties of small molecule donors based on alkoxylated benzothiadiazole unit for non-fullerene small molecule organic solar cells (SM-OSCs).
研究成果
BTCN exhibited higher and balanced electron and hole mobility, and higher extinction coefficient, leading to a best PCE value of 4.62% with BTCN:IDIC-4F. Benzothiadiazole unit is effective in expanding light absorption, modifying energy levels, and enhancing carrier mobility in organic solar cells.
研究不足
The study focuses on the synthesis and initial photovoltaic characterization of two small molecule donors. Further optimization of device architecture and processing conditions may be required to achieve higher efficiencies.
