In the past, different lead-based ferroelectric perovskite thin films such as Pb(Zr,Ti)O3 (Pb,La)(Zr,Ti)O3 and PbTiO3 were investigated with respect to their photovoltaic efficiency. Nevertheless, due to their high band gaps they only absorb photons in the UV spectral range. The well-known ferroelectric PbFe0.5Nb0.5O3 (PFN), which is in a structure similar to the other three, has not been considered as a possible candidate until now. We found that the band gap of PFN is around 2.75 eV and that the conductivity can be increased from 23 S\/\u00b5m to 35 S\/\u00b5m during illumination. The relatively low band gap value makes PFN a promising candidate as an absorber material.<\/jats:p>","DOI":"10.3390\/ma14226841","type":"journal-article","created":{"date-parts":[[2021,11,14]],"date-time":"2021-11-14T20:51:53Z","timestamp":1636923113000},"page":"6841","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Band Gap of Pb(Fe0.5Nb0.5)O3 Thin Films Prepared by Pulsed Laser Deposition"],"prefix":"10.3390","volume":"14","author":[{"given":"Nicole","family":"Bartek","sequence":"first","affiliation":[{"name":"Institute for Materials Science, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 45141 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7155-2473","authenticated-orcid":false,"given":"Vladimir V.","family":"Shvartsman","sequence":"additional","affiliation":[{"name":"Institute for Materials Science, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 45141 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Houssny","family":"Bouyanfif","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique de la Mati\u00e8re Condens\u00e9e UR2081, Universit\u00e9 de Picardie Jules Verne, 80039 Amiens, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1018-7054","authenticated-orcid":false,"given":"Alexander","family":"Schmitz","sequence":"additional","affiliation":[{"name":"Electronic Materials and Nanostructures and Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerd","family":"Bacher","sequence":"additional","affiliation":[{"name":"Electronic Materials and Nanostructures and Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selina","family":"Olthof","sequence":"additional","affiliation":[{"name":"Institute for Physical Chemistry, University of Cologne, 50939 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Sirotinskaya","sequence":"additional","affiliation":[{"name":"Institute of Technology for Nanostructures, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niels","family":"Benson","sequence":"additional","affiliation":[{"name":"Institute of Technology for Nanostructures, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 47057 Duisburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6895-1334","authenticated-orcid":false,"given":"Doru C.","family":"Lupascu","sequence":"additional","affiliation":[{"name":"Institute for Materials Science, Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 45141 Essen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1230","DOI":"10.1126\/science.aaa8765","article-title":"High-performance transition metal\u2013doped Pt 3 Ni octahedra for oxygen reduction reaction","volume":"348","author":"Huang","year":"2015","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"21599","DOI":"10.1021\/acsami.7b06638","article-title":"Selective Organic Contacts for Methyl Ammonium Lead Iodide (MAPI) Perovskite Solar Cells: Influence of Layer Thickness on Carriers Extraction and Carriers Lifetime","volume":"9","author":"Gelmetti","year":"2017","journal-title":"ACS Appl.
