Depending on individual selenium (Se) supply and thermal conditions for forming CZTSe absorbers on molybdenum (Mo) substrates, the thickness of MoSe<jats:sub>2<\/jats:sub> can vary from a few hundreds of nanometers up to \u2248 1 \u03bcm, which is comparable to the commonly adopted thickness of 1 ~ 1.5 \u03bcm for CZTSe absorbers. In this study, for controlling the thickness of interfacial MoSe<jats:sub>2<\/jats:sub>, thin diffusion barrier layers of silicon oxynitride (SiO<jats:sub>x<\/jats:sub>N<jats:sub>y<\/jats:sub>) are deposited onto Mo layers prior to the growth of CZTSe absorbers in the fabrication process. As a result, a reduction in the thicknesses of MoSe<jats:sub>2<\/jats:sub> layers is achieved. In terms of energy conversion efficiency (<jats:italic>\u03b7<\/jats:italic>), CZTSe solar cells grown on Mo\/SiO<jats:sub>x<\/jats:sub>N<jats:sub>y<\/jats:sub> back contacts suffer a deterioration as the SiO<jats:sub>x<\/jats:sub>N<jats:sub>y<\/jats:sub> layers get thicker. CZTSe solar cells grown on Mo\/SiO<jats:sub>x<\/jats:sub>N<jats:sub>y<\/jats:sub>\/Mo back contacts preserve their efficiencies at \u2248 11% with thin 10 nm SiO<jats:sub>x<\/jats:sub>N<jats:sub>y<\/jats:sub> layers.<\/jats:p>","DOI":"10.1371\/journal.pone.0245390","type":"journal-article","created":{"date-parts":[[2021,1,12]],"date-time":"2021-01-12T23:27:39Z","timestamp":1610494059000},"page":"e0245390","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["SiOxNy back-contact barriers for CZTSe thin-film solar cells"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1310-8611","authenticated-orcid":true,"given":"Wenjian","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hippolyte","family":"Hirwa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Ohland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teoman","family":"Taskesen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulf","family":"Mikolajczak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7231-6686","authenticated-orcid":true,"given":"Devendra","family":"Pareek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00fcrgen","family":"Parisi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Levent","family":"G\u00fctay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,1,12]]},"reference":[{"key":"pone.0245390.ref001","doi-asserted-by":"crossref","first-page":"512","DOI":"10.1002\/pip.2156","article-title":"Kesterites-a challenging material for solar cells","volume":"20","author":"S Siebentritt","year":"2012","journal-title":"Prog.
