采用旋转浇铸法制备体异质结太阳电池，其相分离小分子包括1，4，8，11，15，18，22，25-八己基酞菁(C6PcH2)和富勒烯衍生物1-(3-methoxy-carbonyl)-propyl-1-1-phenyl-(6，6)C61(PCBM)，其功率转换效率超过4.1%。利用加工助剂在不同溶剂中对C6PcH2：PCBM BHJ的表面形貌和相分离进行了控制。讨论了加工助剂对六方结构盘状C6PcH2柱结晶的影响。
Bulk heterojunction (BHJ) solar cells, fabricated by spin casting processes, with phase-separated small molecules including a phthalocyanine derivative, 1,4,8,11,15,18,22,25-octahexylphthalocyanine (C6PcH2), and a fullerene derivative, 1-(3-methoxy-carbonyl)-propyl-1-1-phenyl-(6,6)C61 (PCBM), have been demonstrated to have a power conversion efficiency exceeding 4.1%. The C6PcH2:PCBM BHJ surface morphology and the phase separation have been controlled by utilizing processing additives in various solvents. The effects of the processing additives on the crystallization of the discotic C6PcH2 columns in hexagonal structures have been discussed.
