Three furan fused boron dipyrromethenes (BODIPYs) with a CF 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) of 13.3 mA cm 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%.
三种带有 CF 基团的呋喃并硼二吡咯甲烷（BODIPY）被合成出来，作为用于真空加工有机太阳能电池的近红外吸收材料。最好的单结器件达到了 13.3 mA cm 的短路电流（j）和 6.1%的功率转换效率（PCE）。对于吸收起始波长超过 900nm 的电子给体材料来说，这些值非常有前景。在包含一个近红外 BODIPY 子电池和一个匹配的“绿色”吸收剂子电池的串联太阳能电池中，实现了互补吸收，从而获得了约 10%的 PCE。
