The constructed solar device comprises an ITO-coated glass substrate/titanium dioxide/poly(3-hexylthiophene-2,5-diyl):phenyl-C61-butyric acid methyl ester)/poly(3,4ethylenedioxythiophene):poly(styrene sulfonate):AuQDs/silver grating structure. The AuQDs are introduced into the hole transport layer (PEDOT:PSS) to increase the absorption in the ultraviolet (UV) light and near-UV light regions, which give rise to the light harvesting improvement of the devices in accordance to fluorescence. The plasmonic grating structures are created onto the active layer surface by nanoimprinting method using a PDMS stamp to induce the GC-SPR excitation within the devices. The UV-visible spectra, impedance spectra, current density versus voltage (J-V) characteristics, and atomic force microscopy images of the fabricated devices are investigated. The fluorescence from AuQDs incorporated into the GC-SPR evanescent field on the metal grating surface improves the short-circuit current density (Jsc) and the power conversion efficiency (PCE) in comparison to those of the reference cell and the cells with individual effects from AuQDs and metallic grating structures. The designed device shows an enhancement of photovoltaic efficiency achieved by increasing a PCE value from 3.25% (reference cell) to 3.77%, exhibiting an efficiency increase of 16%. Our results suggest that the improved efficiency of the inverted OSCs is achieved due to the combination of both G-AuQDs and GC-SPR.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博(工)第523号", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "甲第4960号"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kuntamung, Kulrisa", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"date": [{"dateType": "Available", "dateValue": "2022-05-10"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "r3ftk523.pdf", "filesize": [{"value": "2.84MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "2.84MB", "url": {"label": "本文", "objectType": "fulltext", "url": "https://niigata-u.repo.nii.ac.jp/record/2000454/files/r3ftk523.pdf"}, "version_id": "a21ba1f4-837c-4818-8929-e9c7812f3dc4"}, {"date": [{"dateType": "Available", "dateValue": "2022-05-10"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "r3ftk523_a.pdf", "filesize": [{"value": "79.8KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "79.8KB", "url": {"label": "要旨", "objectType": "abstract", "url": "https://niigata-u.repo.nii.ac.jp/record/2000454/files/r3ftk523_a.pdf"}, "version_id": "d7250c3c-3d7c-40d7-b143-03fb235c5994"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "inverted organic solar cells", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "gold quantum dots", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fluorescence", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "metallic grating structure", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "grating-coupled surface plasmon resonance", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "plasmon-enhanced fluorescence", "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": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_title": "Improvement of Inverted Organic Solar Cells by Combination of Gold Quantum Dots and Plasmonic Grating Structure", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Improvement of Inverted Organic Solar Cells by Combination of Gold Quantum Dots and Plasmonic Grating Structure", "subitem_title_language": "en"}, {"subitem_title": "金量子ドットとプラズモニックグレーティング構造の組み合わせによる逆型有機太陽電池の特性向上に関する研究", "subitem_title_language": "ja"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "564"], "permalink_uri": "http://hdl.handle.net/10191/0002000454", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-05-10"}, "publish_date": "2022-05-10", "publish_status": "0", "recid": "2000454", "relation": {}, "relation_version_is_last": true, "title": ["Improvement of Inverted Organic Solar Cells by Combination of Gold Quantum Dots and Plasmonic Grating Structure"], "weko_shared_id": -1}
