The interface quality is found to be strongly affected by the perovskite deposition procedure, and in particular from the environment where the conversion of the starting precursors into the final perovskite is performed (air, nitrogen, or vacuum). The conversion efficiency of the precursors into the hybrid perovskite layer is compared between the different solar cells by looking at the ToF-SIMS intensities of the characteristic molecular fragments from the perovskite and the precursor materials. Energy dispersive X-ray spectroscopy in the STEM confirms the macroscopic ToF-SIMS findings and allows elemental mapping with nanometer resolution. Clear evidence for iodine diffusion has been observed and related to the fabrication procedure.<\/jats:p>","DOI":"10.1021\/acsami.5b08038","type":"journal-article","created":{"date-parts":[[2015,11,2]],"date-time":"2015-11-02T16:35:21Z","timestamp":1446482121000},"page":"26176-26183","source":"Crossref","is-referenced-by-count":131,"title":["Interface\nand Composition Analysis on Perovskite Solar Cells"],"prefix":"10.1021","volume":"7","author":[{"given":"Fabio","family":"Matteocci","sequence":"first","affiliation":[{"name":"University of Rome \u201cTor Vergata\u201d , , via del Politecnico 1 , ,","place":["Rome, Italy, 00133"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Busby","sequence":"additional","affiliation":[{"name":"University of Namur , , ,","place":["Namur, Belgium, B-5000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Jacques","family":"Pireaux","sequence":"additional","affiliation":[{"name":"University of Namur , , ,","place":["Namur, Belgium, B-5000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Divitini","sequence":"additional","affiliation":[{"name":"University of Cambridge , , 27 Charles Babbage road , , ,","place":["Cambridge, U.K., CB3 0FS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefania","family":"Cacovich","sequence":"additional","affiliation":[{"name":"University of Cambridge , , 27 Charles Babbage road , , ,","place":["Cambridge, U.K., CB3 0FS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Ducati","sequence":"additional","affiliation":[{"name":"University of Cambridge , , 27 Charles Babbage road , , ,","place":["Cambridge, U.K., CB3 0FS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aldo","family":"Di Carlo","sequence":"additional","affiliation":[{"name":"University of Rome \u201cTor Vergata\u201d , , via del Politecnico 1 , ,","place":["Rome, Italy, 00133"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2015,11,2]]},"reference":[{"key":"2026090310252809400_cit1","doi-asserted-by":"publisher","first-page":"1473","DOI":"10.1126\/science.267.5203.1473","article-title":"Conducting\nLayered Organic-inorganic Halides Containing &lt;110&gt;-Oriented\nPerovskite Sheets","volume":"267","author":"Mitzi","year":"1995","journal-title":"Science"},{"key":"2026090310252809400_cit2","doi-asserted-by":"publisher","first-page":"6050","DOI":"10.1021\/ja809598r","article-title":"Organometal Halide Perovskites as Visible-Light Sensitizers\nfor Photovoltaic Cells","volume":"131","author":"Kojima","year":"2009","journal-title":"J.
