金属卤化物钙钛矿已被证明是低成本和高性能光伏应用的最有前途的材料之一。然而，由于钙钛矿薄膜在平面衬底上的易受影响的结晶过程以及器件内内部界面的物理和光电性质的高灵敏度，不同实验室的研究人员在制造具有平面异质结器件结构的高效钙钛矿太阳能电池时仍然经历较差的再现性。在这篇方法论文中，我们提供了关于在基于一步溶液处理的甲基铵三碘化铅（MAPbI 3）钙钛矿薄膜的“常规”n-i-p和“倒置”p-i-n架构中制造平面钙钛矿太阳能电池的试剂，设备和程序的详细信息。我们讨论了影响钙钛矿结晶和器件界面的关键参数。该方法为平面异质结的可重复性制备提供了指导。
Metal halide perovskites have been demonstrated as one of the most promising materials for low-cost and high-performance photovoltaic applications. However, due to the susceptible crystallization process of perovskite films on planar substrates and the high sensitivity of the physical and optoelectronic nature of the internal interfaces within the devices, researchers in different laboratories still experience poor reproducibility in fabricating efficient perovskite solar cells with planar heterojunction device structures. In this methods paper, we present detailed information on the reagents, equipment, and procedures for the fabrication of planar perovskite solar cells in both “regular” n-i-p and “inverted” p-i-n architectures based on one-step solution-processed methylammonium lead triiodide (MAPbI3) perovskite films. We discuss key parameters affecting the crystallization of perovskite and the device interfaces. This methods paper will provide a guideline for the reproducible fabrication of planar het...
