Here, we innovatively employed a molecular self\u2010assembly approach to obtain a series CH<jats:sub>3<\/jats:sub>NH<jats:sub>3<\/jats:sub>Pb<jats:sub>(1\u2212<jats:italic>x<\/jats:italic>)<\/jats:sub>Sn<jats:sub>x<\/jats:sub>I<jats:sub>3<\/jats:sub> (0\u2264<jats:italic>x<\/jats:italic>\u22641) perovskite thin films with full coverage. The optimized planar CH<jats:sub>3<\/jats:sub>NH<jats:sub>3<\/jats:sub>Pb<jats:sub>0.75<\/jats:sub>Sn<jats:sub>0.25<\/jats:sub>I<jats:sub>3<\/jats:sub> PSC with inverted structure was consequently realized with a maximum power conversion efficiency (PCE) over 14\u2009%, which displayed a stabilized power output (SPO) over 12\u2009% within 200\u2005s at 0.6\u2005V forward bias. Afterward, we investigated the factors that limited the efficiency improvement of hybrid Sn\u2013Pb PSCs, and analyzed the possible reason of the hysteresis effect occurred even in the inverted structure cell. Particularly, the oxidation of hybrid Sn\u2013Pb perovskite thin film was demonstrated to be the main reason that limited its further efficiency improvement. The imbalance of charge transport was intensified, which was associated with the increased hole defect\u2010state density and decreased electron defect\u2010state density after Sn was introduced. This study helps tackle the intractable issue regarding the toxic Pb in perovskite devices and is a step forward toward realizing lead\u2010free PSCs with high stability and efficiency.<\/jats:p>","DOI":"10.1002\/cssc.201700880","type":"journal-article","created":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T21:52:45Z","timestamp":1498168365000},"page":"3839-3845","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Molecular Self\u2010Assembly Fabrication and Carrier Dynamics of Stable and Efficient CH<sub>3<\/sub>NH<sub>3<\/sub>Pb<sub>(1\u2212<i>x<\/i>)<\/sub>Sn<sub><i>x<\/i><\/sub>I<sub>3<\/sub> Perovskite Solar Cells"],"prefix":"10.1002","volume":"10","author":[{"given":"Jiandong","family":"Fan","sequence":"first","affiliation":[{"name":"Institute of New Energy Technology College of Information Science and Technology Jinan University  Guangzhou 510632 P.
