Next, we also identified all the organic perovskites mentioned in the synthesis-paragraphs we extracted. We used ChemDataExtractor to get all the chemicals present in our database, from which we filtered out the perovskites. We were able to acquire more than 350 uniquely mentioned organic perovskites, most of which are MA based (>40%) while Formamidinium (FA) and Butylammonium (BA) based perovskites constitute around 10% each. A full list of these perovskites is given in the supplementary material. As solvents are required for different activities during perovskite synthesis , we looked up for their mutual distribution in the synthesis paragraphs. Our study reveals that most of the solvents are reported in conjunction with MA lead halide perovskites. This is not surprising given that the MA-based perovskites have been attractive due to higher efficiency, and better stability . We further looked into the distribution of these organic perovskites based on their frequency of mutual occurrences with the solvents and plotted the chart shown in Figure . This chart shows that out of all the associations between organic perovskites and solvents, more than 3/4 th involve MA lead halide perovskites. This reflects the scale of study conducted on these perovskites so far. FA and BA based perovskites seem to offer alternative choices, but their number is dwarfed by that of the MA based ones.
