In spite of the high development potential ofOPVCs,consider- able improvement oftheir stability under operational conditions needs to be achieved.Device durability that involve schemical stability and degradation of polymers has always been an impor- tant issue for OPVCs.Studies have indicated that the degradation mechanisms in OPVCs include reaction with O2, H2O, and the electrode materials.Therefore,to increase thestability of OPVCs requires careful selection of donor,acceptor,electrode,and encapsulation materials. As for the interface stability issue,aluminum,titanium and silver have been used as the bottom cathode and reflective layer of top-illuminated OPVCs [73–75], These metal-based electrodes showed superior sheet resistance to those of the conventional ITO electrodes. Studies of unencapsulated OPVC lifetime have demon- strated efficiency half life of greater than 1500h.Potscavage et al. have noted that the shelf life time of apentacene/C60 cell encapsulated with an Al2O3 film deposited by atomic layer deposition has degraded by 6% over a 6100h period,compared to a lifetime of 10 h for an unencapsulated cell. google的不要 |

仅供参考： 尽管OPVC有巨大的发展潜力，他们在运行条件下的稳定性有必要实现相当大的改善。涉及化合物稳定性和聚合物降解的设备耐久性一直是OPVC的一个重要问题。研究提示OPVC降解机制包括与O2、H2O和电极材料的反应。因此，增加OPVC的稳定性需要精心挑选供体、受体、电极和封装材料。至于界面稳定性的问题，铝，钛和银已被用来作为底部的阴极和顶部照明OPVC的反射层，这些基于金属的电极与传统的ITO电极相比表现出优越的薄层电阻。 对未封装OPVC寿命的研究已经表明其效率半衰期大于1500小时。Potscavage等注意到通过原子层沉积氧化铝膜的非并五苯/C60电池的保质期在6100小时中退化6％，而未封装电池的寿命仅10小时。 |
