The BLiS structure consists of a flat silver back-reflector with an overlying light-scattering bilayer which is made of a TiO<jats:sub>2<\/jats:sub> dielectric nanoparticles layer with micron-sized inverted pyramidal cavities, buried under a flat-topped silicon nanoparticles layer. The optical properties of this BLiS back-reflector show high broadband and wide angular distribution of diffuse light-scattering. The efficient light-scattering by the buried inverted pyramid back-reflector is shown to effectively improve the short-circuit-current density and efficiency of the overlying n-i-p amorphous silicon solar cells up to 14% and 17.5%, respectively, compared to the reference flat solar cells. A layer of TiO<jats:sub>2<\/jats:sub> nanoparticles with exposed inverted pyramid microstructures shows equivalent light scattering but poor fill factors in the solar cells, indicating that the overlying smooth growth interface in the BLiS back-reflector helps to maintain a good fill factor. The study demonstrates the advantage of spatial separation of the light-trapping and the semiconductor growth layers in the photovoltaic back-reflector without sacrificing the optical benefit.<\/jats:p>","DOI":"10.1051\/epjpv\/2019011","type":"journal-article","created":{"date-parts":[[2020,2,4]],"date-time":"2020-02-04T09:09:24Z","timestamp":1580807364000},"page":"2","source":"Crossref","is-referenced-by-count":6,"title":["Nanomolded buried light-scattering (BLiS) back-reflectors using dielectric nanoparticles for light harvesting in thin-film silicon solar cells"],"prefix":"10.1051","volume":"11","author":[{"given":"Derese","family":"Desta","sequence":"first","affiliation":[]},{"given":"Rita","family":"Rizzoli","sequence":"additional","affiliation":[]},{"given":"Caterina","family":"Summonte","sequence":"additional","affiliation":[]},{"given":"Rui N.","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"Arne Nylandsted","family":"Larsen","sequence":"additional","affiliation":[]},{"given":"Peter","family":"Balling","sequence":"additional","affiliation":[]},{"given":"Sanjay K.","family":"Ram","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2020,2,4]]},"reference":[{"key":"R1","unstructured":"Nelson J., Physics of Solar Cell\n (Imperial College Press, London, 2008)"},{"key":"R2","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1002\/pip.533","volume":"12","author":"Shah","year":"2004","journal-title":"Prog.
