The current-voltage characteristics of benzoporphine-fullerene solar cells were measured subsequent to the deposition of Al as a cathode material. Even in vacuum, a shift in the open circuit voltage was observed at 20 min after Al deposition. Moreover, the displacement of inert gases (N(2)or Ar) in the evaporation chamber enhanced the photovoltaic parameters. The power conversion efficiency was increased by 24% over the initial characteristics (from 1.04% to 1.29%), which indicates that the structure of the organic-metal interface changed rapidly after Al deposition, even if the process was performed in an air-free glovebox.
在沉积作为阴极材料的铝之后，测量了苯并卟啉-富勒烯太阳能电池的电流-电压特性。即使在真空中，在铝沉积20分钟后也观察到开路电压的偏移。此外，蒸发室内惰性气体（N₂或Ar）的置换提高了光伏参数。功率转换效率比初始特性提高了24%（从1.04%提高到1.29%），这表明即使该过程在无空气的手套箱中进行，铝沉积后有机-金属界面的结构也会迅速变化。
