摘要
<jats:title>Abstract</jats:title><jats:p>Since a hybrid perovskite‐based solar cell was reported for the first time, its efficiency and stability were boosted to remarkably high levels. With record efficiencies beyond 22 % and record stability up to 10 000 h under working conditions, perovskite solar cells are a promising candidate for further commercial applications. Among the myriads of fabrication methods to deposit perovskite films, we have chosen a unique technique that only needs methylamine gas (CH<jats:sub>3</jats:sub>NH<jats:sub>2</jats:sub>) to convert the inorganic film. In contrast to all other fabrication methods, this is based on room temperature and exposure to an organic gas exposure at ambient pressure, which can be easily employed for large‐area and fast coatings. In this Review, the advantages and characteristics of methylamine gas applications will be discussed. First, we will evaluate the different techniques to convert an inorganic film into a perovskite with an emphasis on the chemical interactions. Then, we will summarize the applications of methylamine gas to “heal” and improve the perovskite films prepared by other methods.</jats:p>
