摘要

本文以bodipy -香豆素三联体为基础，合成了一种新的不融合富勒烯受体BDP-2C，其光带隙约为1.51 eV， HOMO和LUMO能级分别约为-5.50 eV和-4.00 eV。采用BDP-2C作为PM6:Y6中的客体组分，优化后的三元有机太阳能电池的功率转换效率（PCE）约为15.09%，能量损失低至0.503 eV。平衡电荷输运和抑制电荷复合、缩短电荷提取时间和延长载流子寿命是提高三元有机太阳能电池PCE的主要因素。

BODIPY-coumarin triad as acceptor for ternary Non-Fullerene Solar Cells with over 15% Efficiency.

Herein, we synthesized a new non-fused fullerene-free acceptor based on the BODIPY-coumarin triad, BDP-2C, which exhibits a medium optical bandgap of about 1.51 eV, and HOMO and LUMO energy levels about -5.50 eV and -4.00 eV, respectively. Employing BDP-2C as a guest component in PM6:Y6, the resulting optimized ternary organic solar cells attained a power conversion efficiency (PCE) of about 15.09% with a low energy loss of 0.503 eV. The balanced charge transport and suppressed charge recombination, shorter charge extraction time, and prolonged charge carrier lifetime are the factors that enhance the PCE of ternary organic solar cells.
