An n-i-p type of organic-inorganic hybrid bifacial solar cells was constructed with a ZnO/polyaniline/NiO _x heterostructure, in which vertically aligned ZnO nanorods (ZnO_Nd) were synthesized by a facile electrochemical deposition process and act as an electron-transport layer. Semitransparent p-type semiconducting NiO _x films were utilized as a hole-transport layer. Devices based on the ZnO_Nd considerably outperform those employing ZnO thin films. The contact and electrical properties of NiO _x can be carefully tuned through controlling the deposition parameters as well as surface treatments. Intimate contact between NiO _x with PANI, created by in situ electrochemical polymerization, greatly improves the charge movement. Furthermore, an O₂-plasma treatment of the NiO _x film has a significant impact on the performance of polyaniline/ZnO_Nd hybrid photovoltaic devices, reflected by the enhancement in the fill-factor and efficiency. The power conversion efficiency of the ZnO_Nd/PANI/NiO _x device under the optimized O₂ plasma condition can reach up to 2.79% under AM1.5 illumination.

使用ZnO /聚苯胺/ NiO _x异质结构构建了nip型有机-无机混合双面太阳能电池，其中通过简便的电化学沉积工艺合成了垂直排列的ZnO纳米棒（ZnO _Nd），并用作电子传输层。将半透明的p型半导体NiO _x膜用作空穴传输层。基于ZnO _Nd的器件大大优于采用ZnO薄膜的器件。NiO _x的接触和电特性可以通过控制沉积参数以及表面处理来仔细调整。NiO _x与PANI的紧密接触，由原位产生 电化学聚合，大大提高了电荷运动。此外，NiO _x膜的O ₂等离子体处理对聚苯胺/ ZnO _Nd混合光伏器件的性能具有重大影响，这可通过提高填充系数和效率来体现。在优化的O ₂等离子体条件下，ZnO _Nd / PANI / NiO _x器件的功率转换效率在AM1.5照明下可达到2.79％。
