The short-circuit dark-current was observed for the Al/dye cells with the mixed solid in contrast to that with the pure H2tpp solid, and it increased with increasing molar ratio (R) of o-chloranil to H2tpp. Furthermore, a much larger photocurrent was observed for the mixed-solid cells than for the pure H2tpp cell, but in the former cells in contrast to the latter cell, the open-circuit photovoltage was approximately the same as the open-circuit dark-voltage. These results indicate that the photocurrent of the mixed-solid cells was from the photocorrosion of the Al electrode. The short-circuit photocurrent action spectra obtained by irradiating from the Al side followed the absorption spectra of the dye solid films on the Al substrate below the R value of about 1, but above R = 1.5, a clear difference was observed in the spectra. This difference arises because a small amount of metal-free porphyrin dications, which is hardly detected by UV-visible spectra, was produced in the immediate neighborhood of the Al electrode when spin-coated with a larger R value because of dark-corrosion of aluminum by both assistance of the hydrogen bonds (between H2tpp and o-chloranil) and the electric field (in a Schottky barrier built during the spin coating). Thus the metal-free porphyrin dications efficiently underwent a photoinduced charge-separation by the potential gradient in the Schottky barrier.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科先端機能物質","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00007420","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Electrochemical Society"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1149/1.1391832","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00697016","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0013-4651","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takahashi, Kohshin"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Terada, Tetsuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Takahiro"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Komura, Teruhisa"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Murata, Kazuhiko"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-TAKAHASHI-K-1717.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-TAKAHASHI-K-1717.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/7433/files/TE-PR-TAKAHASHI-K-1717.pdf"},"version_id":"967a67d5-4c93-46fc-ba66-51ec20d08bd0"}]},"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":"Contribution of electric-field-induced metal-free porphyrin dication to photocurrent in mixed solid of metal-free porphyrin and o-chloranil/Al Schottky-barrier cell","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Contribution of electric-field-induced metal-free porphyrin dication to photocurrent in mixed solid of metal-free porphyrin and o-chloranil/Al Schottky-barrier cell"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"7433","relation_version_is_last":true,"title":["Contribution of electric-field-induced metal-free porphyrin dication to photocurrent in mixed solid of metal-free porphyrin and o-chloranil/Al Schottky-barrier cell"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:28:57.794225+00:00"}
