Our results show that the valence band maximum and conduction band minimum shift down in energy by 110 meV and 77 meV as temperature increases from 28 °C to 85 °C. Density functional theory calculations using slab structures show that the decreased orbital splitting due to thermal expansion is a major contribution to the experimentally observed shift in energy levels. Our results have implications for solar cell performance under operating conditions with continued sunlight exposure and increased temperature.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825894860977792","@type":"Researcher","foaf:name":[{"@value":"Benjamin J.
