An upscalable chemical vapor deposition setup has been built‐up and employed in producing methylammonium lead iodide (MAPI) thin film perovskite solar cells, leading to a maximum efficiency of 12.9%. The method makes use of methylamine gas and hydrogen iodide gas to transform a predeposited layer of lead(II)iodide (PbI₂) into MAPI. Although the reaction mechanism includes the intermediate phases lead oxide (PbO) and lead hydroxide (Pb(OH)₂), indicated at least on the surface of the samples by XPS, neither species could be observed in XRD measurements of the stepwise reaction, which show a mixture of highly oriented cubic and tetragonal MAPI perovskite lattice systems.

利用甲胺气体（CH3NH2）和碘化氢气体的化学气相沉积法制备甲基碘化碘化铅（CH3NH3PbI3）薄膜钙钛矿太阳能电池

建立了可升级的化学气相沉积装置，并用于生产甲基铵碘化铅（MAPI）薄膜钙钛矿太阳能电池，最高效率为12.9％。该方法利用甲胺气体和碘化氢气体将碘化铅（II）（PbI ₂）的预沉积层转化为MAPI。尽管反应机理包括中间相氧化铅（PbO）和氢氧化铅（Pb（OH）₂），至少在XPS样品表面上显示，但在逐步反应的XRD测量中均未观察到任何物质。显示出高取向立方和四方MAPI钙钛矿晶格体系的混合物。
