Perovskites have recently emerged as the holy grail of photovoltaics, reaching in a decade of research a solar cell certified efficiency of 25.5% for a single-junction device, thus rivaling the performance of well-established technologies. Despite their excellent performances, which have been exploited in a large number of (opto) electronic devices well beyond solar cells (such as gas sensors, transistors, thermoelectric and piezoelectric generators, light-emitting diodes, lasers, and photodetectors), the reduced long-term stability of the large majority of inorganic and hybrid perovskites still represents the main obstacle preventing their commercialization and, therefore, their optimization is one of the main research topics in the field. Comparative analysis of specular x-ray diffraction and complementary GIXD measurements indicates that the use of DMF/DMSO mixed solvents promotes the strengthening of a dominant 100 or 210 texturing, as compared the case of pure DMF.
