Abstract

Carbon-based top electrodes have significant value in enhancing the stability and reducing the cost of perovskite solar cells (PSCs). However, the fabrication process for carbon-based top electrodes in large-area, high-performance perovskite solar modules (PSMs) still lacks practical techniques. In this work, we reference the bag moulding process and use a plasticine-like uncured carbon paste to prepare the top electrode for small-area PSCs and PSMs. Benefiting from the uniform pressure provided by the bag pressing process, this carbon electrode can make sufficiently good electrical contact with the hole transport layer in the large-area device in a single pass. After further removing excess fluid, the device can achieve efficiencies of 18.57 % (∼0.15 cm²) and 14.44 % (∼10 cm²) with good stability. This convenient top electrode preparation method at room temperature offers a novel technological solution for the commercial application of large-area PSMs.

用于钙钛矿太阳能电池和组件的袋压塑碳电极

碳基顶电极在提高钙钛矿太阳能电池的稳定性和降低成本方面具有重要的价值。然而，大面积、高性能钙钛矿太阳能组件（psm）的碳基顶电极的制造工艺仍然缺乏实用的技术。在这项工作中，我们参考了袋子成型工艺，并使用类似塑料的未固化碳糊来制备小面积PSCs和psm的顶部电极。得益于袋压工艺提供的均匀压力，该碳电极可在一次过程中与大面积装置中的空穴传输层实现足够好的电接触。在进一步去除多余的液体后，该装置可以实现18.57% （~ 0.15 cm2）和14.44% （~ 10 cm2）的效率，并具有良好的稳定性。这种方便的室温顶电极制备方法为大面积psm的商业化应用提供了一种新的技术解决方案。
