To investigate the role of interface, the perovskite morphology was intentionally modified by varying HC(NH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>I concentration. Surface and grain sizes of the deposited FAPbI<jats:sub>3<\/jats:sub> became rougher and larger as the HC(NH<jats:sub>2<\/jats:sub>)<jats:sub>2<\/jats:sub>I concentration decreased from 58.2 to 40.7\u2005m<jats:sc>M<\/jats:sc>. Average photocurrent was improved but photovoltage deteriorated slightly with decreasing concentration. Consequently, the average efficiency was improved from 7.82\u2009% to 10.70\u2009% and the best efficiency of 12.17\u2009% was obtained at 40.7\u2005m<jats:sc>M<\/jats:sc>. Photoluminescence (PL) at TiO<jats:sub>2<\/jats:sub>\/FAPbI<jats:sub>3<\/jats:sub> interface was reduced with decreasing concentration, which was, however, reversed at FAPbI<jats:sub>3<\/jats:sub>\/spiro\u2010MeOTAD one. By correlating PL data and the photovoltaic performance, we concluded that the TiO<jats:sub>2<\/jats:sub>\/perovskite interface plays a crucial role in determining photocurrent while the perovskite\/spiro\u2010MeOTAD interface is important in governing photovoltage.<\/jats:p>","DOI":"10.1002\/cssc.201403442","type":"journal-article","created":{"date-parts":[[2015,4,16]],"date-time":"2015-04-16T13:01:15Z","timestamp":1429189275000},"page":"2414-2419","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":69,"title":["On the Role of Interfaces in Planar\u2010Structured HC(NH<sub>2<\/sub>)<sub>2<\/sub>PbI<sub>3<\/sub> Perovskite Solar Cells"],"prefix":"10.1002","volume":"8","author":[{"given":"Dong\u2010Jin","family":"Seol","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin\u2010Wook","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nam\u2010Gyu","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,4,16]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep00591"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja809598r"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1039\/c1nr10867k"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature12340"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1228604"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp412407j"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature12509"},{"key":"e_1_2_6_8_2","unstructured":"http:\/\/www.nrel.gov\/ncpv\/images\/efficiency_chart.jpg."},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1243167"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1243982"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1039\/c3ta10518k"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/cber.19270600550"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp409025w"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1085\/jgp.100.3.373"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic401215x"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201401137"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1039\/c3ee43822h"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2014.181"},{"key":"e_1_2_6_19_2","first-page":"98","volume":"2","author":"Scherrer P.","year":"1918","journal-title":"Goettinger Nachrichten Math.
