通过在铟锡氧化物（ITO）/酞菁锌（ZnPc）界面插入酞菁锂（LiPc）层，提高了ZnPc/C60异质结太阳能电池的能量转换效率。光电子能谱结果表明，LiPc层降低了ITO/ZnPc界面空穴传输的势垒高度。在M-酞菁（M=H2、Cu和TiO）/C60电池中也观察到通过插入LiPc层的功率转换效率的类似改善。
Improvement of power conversion efficiency of a zinc phthalocyanine (ZnPc)/C60 heterojunction solar cell was achieved by inserting a lithium phthalocyanine (LiPc) layer at the indium-tin oxide (ITO)/ZnPc interface. The results of photoelectron spectroscopy suggest that the barrier height for the hole transport at the ITO/ZnPc interface is reduced by the LiPc layer. A similar improvement of the power conversion efficiency by the insertion of a LiPc layer was also observed in M-phthalocyanine (M=H2, Cu, and TiO)/C60 cells.
