报道了以氟化酞菁锌为电子给体，富勒烯C60为电子受体的高效单体异质结有机太阳能电池。与常用的吸收剂酞菁锌相比，分子氟化为F4 ZnPc导致电离电位增加，随后使有机太阳能电池的开路电压提高约170 mV，而短路电流密度和填充因子几乎保持不变。类似于ZnPc：C60基器件，F4ZnPc：C60太阳能电池的器件特性可以通过在沉积期间通过衬底加热来改善共混层形态而进一步增强。F4ZnPc是一种高效的施主材料，在单异质结有机太阳能电池中可以实现4.6%的功率转换效率。
Efficient single bulk heterojunction organic solar cells based on blends of a fluorinated zinc phthalocyanine as electron donor and fullerene C60 as electron acceptor are reported. In comparison to the commonly used absorber zinc phthalocyanine, the fluorination of the molecule to F4ZnPc leads to an increase in ionisation potential and subsequently to an improvement of about 170 mV in the open circuit voltage of organic solar cells, while the short circuit current density and fill factor remain nearly unchanged. Similar to ZnPc:C60-based devices, the device characteristics of F4ZnPc:C60 solar cells can be further enhanced by improving the blend layer morphology by substrate heating during deposition. F4ZnPc is an efficient donor material that can achieve a 4.6% power conversion efficiency in single heterojunction organic solar cells.
