Here, we propose to use pre-synthesized crystalline perovskite with perfect stoichiometry to control and lower the density of defects from precursors by the powder engineering method. Compared with raw materials (i.e., PbI₂ and FAI) based perovskites, the average efficiency of the PSCs fabricated based on these pre-synthesized perovskite precursors increased from 18.62% to 19.85%. Moreover, the unwanted intermediate chemical compositions (i.e., the unreacted phases and residual solvent) in the raw material-based perovskite films were significantly reduced in the pre-synthesized δ-FAPbI₃ and α-FAPbI₃ perovskites according to the secondary ion mass spectroscopy depth profiling results. Finally, we obtained the champion efficiency of 22.76% for α-FAPbI₃ and 23.05% for FAPb(I0.9Br0.1)₃ based PSCs. Long-term operational stability measurements of the encapsulated FAPb(I₀.₉Br₀.₁)3 based PSCs showed a slow decay and maintained the efficiency about 88% after 1200 h (T₈₀ > 2000 h). Furthermore, a proof-of-concept integrated perovskite solar module-lithium ion battery-light-emitting diode device was demonstrated.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.nanoen.2021.106152","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S2211285521004080?via%3Dihub","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"This article/chapter was published in Nano Energy,87, Guoqing Tong,Dae-Yong Son,Luis K.Ono,Hyung-Been Kang,Sisi Hea,Longbin Qiua,Hui Zhanga,Yuqiang Liua,Jeremy Hieullea,Yabing Qi, Removal of residual compositions by powder engineering for high efficiency formamidinium-based perovskite solar cells with operation lifetime over 2000 h,106152,© Elsevier 2021"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2211-2855","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-05-13"}],"displaytype":"detail","filename":"MS20210928.pdf","filesize":[{"value":"3.1 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (https://creativecommons.org/licenses/by-nc-nd/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MS20210928","url":"https://oist.repo.nii.ac.jp/record/2311/files/MS20210928.pdf"},"version_id":"6837b249-c5c4-4e74-a3c1-e80bbd491ece"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Perovskite solar cells","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Powder engineering","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Solar modules","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Efficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Operational stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Removal of residual compositions by powder engineering for high efficiency formamidinium-based perovskite solar cells with operation lifetime over 2000 hours","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Removal of residual compositions by powder engineering for high efficiency formamidinium-based perovskite solar cells with operation lifetime over 2000 hours","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"33","path":["48","168"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-06"},"publish_date":"2021-10-06","publish_status":"0","recid":"2311","relation_version_is_last":true,"title":["Removal of residual compositions by powder engineering for high efficiency formamidinium-based perovskite solar cells with operation lifetime over 2000 hours"],"weko_creator_id":"33","weko_shared_id":33},"updated":"2023-06-26T11:20:26.435221+00:00"}
