This work demonstrates that unetched substrates can be reliably used in perovskite solar cell (PSC) fabrication. Chemical etching and laser patterning of the bottom electrodes are time- and resource-consuming processes. In particular, when testing novel conductive substrate materials, such as metallic or bio-based substrates, etching or patterning could be entirely unfeasible or could require significant process optimization. Avoiding these steps could accelerate research on PSCs, yet the literature shows no attempts to override these steps. Here, PSCs were fabricated and characterized using three-dimensionally printed holders with spring-loaded pins. We show that devices made on unetched substrates have, on average, a similar performance to those made on etched substrates (16 ± 1% and 16.0 ± 0.7%, respectively). Our study provides a new strategy for fabricating PSCs, particularly when etching and laser patterning are impractical.
这项工作表明，未蚀刻的衬底可可靠地用于钙钛矿太阳能电池（PSC）制造。底部电极的化学蚀刻和激光图案化是耗时且耗费资源的过程。特别是在测试新型导电衬底材料（如金属或生物基衬底）时，蚀刻或图案化可能完全不可行，或者可能需要大量的工艺优化。避免这些步骤可以加速PSC的研究，但文献表明尚无尝试跳过这些步骤。在此，使用带有弹簧销的三维打印夹具制造并表征了PSC。我们表明，在未蚀刻衬底上制造的器件平均性能与在蚀刻衬底上制造的器件相似（分别为16±1%和16.0±0.7%）。我们的研究为制造PSC提供了一种新策略，特别是在蚀刻和激光图案化不可行的情况下。
