Fundamental photovoltaic parameters such as current density–voltage characteristics of flexible NiO/ZnO solar cells were investigated; the study revealed the degradation and recovery properties of the cells. The open-circuit voltage and shunt resistance of the flexible NiO/ZnO solar cells tended to decrease subsequent to bending; however, the short-circuit current and series resistance remained constant. This indicated that the number of defects caused by bending tend to increase proximate to the NiO/ZnO interface as compared to that of the bulk of the flexible solar cell. Moreover, the decreased solar cell performance caused by bending improved through heat treatment at 150 C for 15min. The results obtained could serve as the first step towards the realization of flexible visible-light-transparent solar cells using polycrystalline films.

研究了柔性 NiO/ZnO 太阳能电池的电流密度-电压特性等基本光伏参数；该研究揭示了细胞的降解和恢复特性。柔性NiO/ZnO太阳能电池的开路电压和分流电阻随弯曲而降低；然而，短路电流和串联电阻保持不变。这表明与柔性太阳能电池的主体相比，由弯曲引起的缺陷数量在靠近 NiO/ZnO 界面处趋于增加。此外，通过在 150°C 下热处理 15 分钟改善了由弯曲引起的太阳能电池性能下降。获得的结果可以作为使用多晶薄膜实现柔性可见光透明太阳能电池的第一步。
