Due to the significantly higher efficiencies and higher radiation hardness the higher manufacturing costs in comparison with silicon solar cells are overcompensated. However, the development of the current state-of-the-art triple-junction solar cell for space applications consisting of the material combination Ga(0.5)In(0.5)P/Ga(0.99)In(0.01)As/Ge has been driven close to its practical efficiency limits of 30 percent. In order to decrease the overall solar array costs further, new concepts have to be developed and investigated. The European Space Agency (ESA) follows different promising approaches which are firstly related to the increase of solar cell efficiencies. In addition, ways to reduce the cell thickness are investigated in order to bring down the specific power given in power/mass. Finally, larger cell areas could lead to cost savings in the integration process of the solar cells onto the panel substrate.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063997002","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-07-030","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"ESA ESTEC"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"European Space Agency European Space Research and Technology Center"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Baur, Carsten","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"63997002.pdf","filesize":[{"value":"535.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63997002.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5491/files/63997002.pdf"},"version_id":"cadd413c-a0fd-468e-8c3a-0cbe65201e6e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"太陽電池","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機給電","subitem_subject_scheme":"Other"},{"subitem_subject":"エネルギー変換効率","subitem_subject_scheme":"Other"},{"subitem_subject":"量子効率","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"光電効果","subitem_subject_scheme":"Other"},{"subitem_subject":"ヨーロッパの宇宙計画","subitem_subject_scheme":"Other"},{"subitem_subject":"多接合型太陽電池","subitem_subject_scheme":"Other"},{"subitem_subject":"経費削減","subitem_subject_scheme":"Other"},{"subitem_subject":"solar cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft power supply","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"energy conversion efficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"quantum efficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"photovoltaic effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"European space program","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-junction solar cell","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cost reduction","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Solar cell R & D activities at ESA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Solar cell R & D activities at ESA","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["973","1497","1823","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5491","relation_version_is_last":true,"title":["Solar cell R & D activities at ESA"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:13:55.102819+00:00"}
