The photonic-structured wafers achieved an optical photocurrent of 36.6 mA\/cm<sup>2<\/sup>, mainly due to a broad anti-reflection effect arising from the 693 nm thick nanostructured coatings; whereas the pIBCSC test devices reached 14% efficiency with 705 nm thick TiO<sup><sub>2<\/sub><\/sup> nanostructures, which corresponds to ~30% efficiency gain relative to uncoated pIBCSCs. In addition, several designed structures showed unmatched angular acceptance enhancements in efficiency (up to 63% gain) and photocurrent density (up to 68% gain). \nThe high-performing (yet electrically harmless) light-trapping scheme, here presented, entails a highly promising alternative to conventional texturing for c-Si technological improvement, with straightforward integration in the established photovoltaic industry.<\/p>","DOI":"10.21203\/rs.3.rs-2402326\/v1","type":"posted-content","created":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T03:16:30Z","timestamp":1675394190000},"source":"Crossref","is-referenced-by-count":0,"title":["Optically-boosted planar IBC Solar Cells with Electrically-harmless Photonic Nanocoatings"],"prefix":"10.21203","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6593-8698","authenticated-orcid":false,"given":"Ivan","family":"Santos","sequence":"first","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7533-9469","authenticated-orcid":false,"given":"Miguel","family":"Alexandre","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT, Department of Materials Science, NOVA School of Science and Technology and CEMOP\/UNINOVA"}]},{"given":"Valentin","family":"Mihailetchi","sequence":"additional","affiliation":[{"name":"International Solar Energy Research Center (ISC) Konstanz"}]},{"given":"Tiago","family":"Mateus","sequence":"additional","affiliation":[{"name":"Uninova"}]},{"given":"Ana","family":"Mouquinho","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"given":"Jenny","family":"Boane","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"given":"Ant\u00f3nio","family":"Vicente","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"given":"Daniela","family":"Nunes","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"given":"Ugur","family":"Menda","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Nova School of Science and Techonology (FCT|UNL) and CEMOP\/UNINOVA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7350-649X","authenticated-orcid":false,"given":"Hugo","family":"\u00c1guas","sequence":"additional","affiliation":[{"name":"CENIMAT\/I3N"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4202-7047","authenticated-orcid":false,"given":"Elvira","family":"Fortunato","sequence":"additional","affiliation":[{"name":"CENIMAT\/i3N, Departamento de Ci\u00eancia dos Materiais, Faculdade de Ci\u00eancias e Tecnologia\u2013Universidade NOVA de Lisboa"}]},{"given":"Rodrigo","family":"Martins","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias e Tecnologia, Universidade Nova de Lisboa"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7374-0726","authenticated-orcid":false,"given":"Manuel J.","family":"Mendes","sequence":"additional","affiliation":[{"name":"CENIMAT-I3N, Faculdade de Ciencias e Tecnologia, Universidade Nova de Lisboa"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2402326\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2402326\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T03:16:37Z","timestamp":1675394197000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2402326\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,2,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-2402326\/v1","relation":{},"subject":[],"published":{"date-parts":[[2023,2,3]]},"subtype":"preprint"}}
