Three furan fused boron dipyrromethenes (BODIPYs) with a CF₃ group on the meso-carbon are synthesized as near-infrared absorbing materials for vacuum processable organic solar cells. The best single junction device reaches a short-circuit current (j_sc) of 13.3 mA cm^–2 and a power conversion efficiency (PCE) of 6.1%. These values are highly promising for an electron donor material with an absorption onset beyond 900 nm. In a tandem solar cell comprising a NIR BODIPY subcell and a matching “green” absorber subcell, complementary absorption is achieved, resulting in PCE of ∼10%.

用于有机串联太阳能电池的小分子近红外硼二吡咯亚甲基供体

三个呋喃稠硼dipyrromethenes（BODIPYs）与CF ₃基团的内消旋-碳被合成为用于真空处理的有机太阳能电池的近红外线吸收材料。最佳的单结器件的短路电流（j _sc）为13.3 mA cm ^-2，功率转换效率（PCE）为6.1％。这些值对于吸收起始超过900nm的电子供体材料是非常有前途的。在包括NIR BODIPY子电池和匹配的“绿色”吸收器子电池的串联太阳能电池中，实现了互补吸收，结果PCE约为10％。
