In this work, a 4-band k.p-based method was developed for rocksalt QDs that describes the complete optical properties of arbitrary QD@Host systems, trailblazing the way for the full opto-electronic analysis of quantum-structured solar cells. Starting with the determination of the QD bandgap, and validation against well-established literature results, the electron transition rate is then computed and analysed against the main system parameters. This is followed by a multi-parameter optimization, considering intermediate band solar cells as a promising application, where the best QD configuration was determined, together with the corresponding QD@Host absorption spectrum, in view of attaining the theoretical maximum efficiency (~\u200950%) of this photovoltaic technology. The results show the creation of pronounced sub-bandgap absorption due to the electronic transitions from\/to the quantum-confined states, which enables a much broader exploitation of the sunlight spectrum.<\/p>","DOI":"10.21203\/rs.3.rs-2346995\/v1","type":"posted-content","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T15:25:03Z","timestamp":1674833103000},"source":"Crossref","is-referenced-by-count":0,"title":["Understanding the Potential of Light Absorption in Dots-in-Host Semiconductors"],"prefix":"10.21203","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7533-9469","authenticated-orcid":false,"given":"Miguel","family":"Alexandre","sequence":"first","affiliation":[{"name":"i3N\/CENIMAT, Department of Materials Science, NOVA School of Science and Technology and CEMOP\/UNINOVA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7350-649X","authenticated-orcid":false,"given":"Hugo","family":"\u00c1guas","sequence":"additional","affiliation":[{"name":"CENIMAT\/I3N"}]},{"given":"Elvira","family":"Fortunato","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT, Department of Materials Science, NOVA School of Science and Technology and CEMOP\/UNINOVA"}]},{"given":"Rodrigo","family":"Martins","sequence":"additional","affiliation":[{"name":"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","reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1038\/s41566-022-00960-w","article-title":"Ultrahigh-resolution quantum-dot light-emitting diodes","author":"Meng T","year":"2022","unstructured":"T.
