Since the first publication of all-solid perovskite solar cells (PSCs) in 2012, this technology has become probably the hottest topic in photovoltaics. Proof of this is the number of published papers and the citations that they are receiving—greater than 3,200 and 110,000, respectively— in just the last year (2017). However, despite this intensive effort, the working …
