Abstract Silver nanowire (AgNW) transparent electrodes are promising for flexible perovskite solar cells (PSCs) due to their low cost, high conductivity, high transmittance and roll-to-roll fabrication processes. We resolved problems with incorporating AgNW networks into PSCs such as smooth surface morphology, space filling and chemical stability by employing solution-deposition of conductive ATO nanoparticles onto pre-existing AgNW networks at low temperatures. AgNW/ATO composite transparent electrodes show a transmission of 76–82 % in the visible region with an excellent sheet resistance of 18 O sq−1, similar to the commercial PET/ITO transparent electrodes. To build up flexible PSCs, we adopted an architecture in which the thin film of CH3NH3PbI3 was sandwiched between the ZnO (as the electron-selective layer) and carbon electrode (as the hole-selective layer) on the AgNW/ATO composite transparent electrodes. Under AM 1.5 G and 100 mW cm−2 simulated sunlight illumination, the flexible PSCs based on AgNW/ATO composite transparent electrodes achieved PCEs of 5.07 %. The flexible devices maintained their performance after 100 bending cycles at 6 mm radius of curvature.

基于AgNW/ATO复合透明电极的柔性钙钛矿太阳能电池

摘要 银纳米线 (AgNW) 透明电极因其低成本、高导电性、高透射率和卷对卷制造工艺而有望用于柔性钙钛矿太阳能电池 (PSC)。我们通过在低温下将导电 ATO 纳米粒子溶液沉积到预先存在的 AgNW 网络上，解决了将 AgNW 网络纳入 PSC 的问题，例如光滑的表面形态、空间填充和化学稳定性。AgNW/ATO 复合透明电极在可见光区的透射率为 76-82%，具有 18 O sq-1 的优异薄层电阻，类似于商用 PET/ITO 透明电极。为了建立灵活的 PSC，我们采用了一种结构，其中 CH3NH3PbI3 薄膜夹在 AgNW/ATO 复合透明电极上的 ZnO（作为电子选择层）和碳电极（作为空穴选择层）之间。在 AM 1.5 G 和 100 mW cm-2 模拟阳光照射下，基于 AgNW/ATO 复合透明电极的柔性 PSC 实现了 5.07% 的 PCE。柔性设备在 6 毫米曲率半径弯曲 100 次后仍保持其性能。
