Here, we analyzed the photovoltaic properties of the inverted organic solar cells (IOSCs) by using randomly oriented medium density ZnO nanorods (ZnO-NR) synthesized hydrothermally at low temperature conditions to avoid morphological defects. The IOSC with ZnO-NR (length < 150 nm) of medium density and random orientation showed an improvement of 83% in power conversion efficiency compared to the cell with (length < 20 nm) hydrothermally grown ZnO-NR. The optimized hydrothermal growth conditions for ZnO-NR enhanced the photovoltaic performance indicators by reducing recombination rate evidenced by the photovoltaic data. The qualitative elemental analysis of the ZnO-NR based interface was performed by the EDX, which confirmed that the as-grown ZnO-NR contain the Zn and O elements.
在此，我们通过使用在低温条件下通过水热法合成的随机取向的中密度ZnO纳米棒（ZnO-NR）来分析倒置有机太阳能电池（IOSC）的光伏特性，以避免形态缺陷。与具有水热生长的（长度<20nm）ZnO-NR的电池相比，具有中密度和随机取向的（长度<150nm）ZnO-NR的IOSC在功率转换效率方面提高了83%。ZnO-NR的优化水热生长条件通过降低光伏数据证明的复合率提高了光伏性能指标。通过能谱仪（EDX）对基于ZnO-NR的界面进行了定性元素分析，证实生长的ZnO-NR包含Zn和O元素。
