Abstract

We present significant light stability enhancement of nonfullerene acceptor inverted organic photovoltaics by incorporating a mixed nanocomposite metal oxide electron transporting layer. Using an appropriate mixture of ZnO:SnO₂ nanoparticles as an electron transporting layer in a PBDB-TF-T1 (T1):IT4F based organic solar cell device mitigates light induced photodegradation by lowering the defect formation at the active layer interface. We propose that the mixed metal oxide ETL act as hole scavengers that reduces the photocatalytic reaction of its surface. The optimized nanocomposite mixture of ZnO:SnO₂ 10:90 (%V) provides higher light stability (ISOS-L2 protocol), prolonging the inverted OSCs lifetime (80% of the initial PCE, T80) by ∼16.5 times compared to the commonly used pristine ZnO electron transporting layer.

采用混合纳米复合金属氧化物电子传输层改善非富勒烯受体倒置有机太阳能电池的光稳定性

通过加入混合纳米复合金属氧化物电子传输层，我们提出了非富勒烯受体倒置有机光伏的光稳定性显著增强。在PBDB-TF-T1 (T1):IT4F基有机太阳能电池器件中，采用适当的ZnO:SnO2纳米粒子混合物作为电子传输层，通过降低活性层界面处的缺陷形成，减轻了光诱导的光降解。我们提出混合金属氧化物ETL作为空穴清除剂，减少其表面的光催化反应。优化后的ZnO:SnO2 10:90 （%V）纳米复合混合物具有更高的光稳定性（iso - l2协议），与常用的原始ZnO电子传输层相比，倒置OSCs寿命（初始PCE的80%，T80）延长了约16.5倍。
