Article history: This paper describes the preparation, characterizations and the antireﬂection (AR) coating application in Received 28 October 2015 crystalline silicon solar cells of sol–gel derived SiC–SiO nanocomposite. The prepared SiC–SiO nanocom- 2 2 Received in revised form 9 January 2016 posite was effectively applied as AR layer on p-type Si-wafer via two step processes, where the sol–gel of Accepted 8 February 2016 precursor solution was ﬁrst coated on p-type Si-wafer using spin coating at 2000 rpm and then subjected Available online 9 February 2016 to annealing at 450 C for 1 h. The crystalline, and structural observations revealed the existence of SiC and SiO phases, which noticeably conﬁrmed the formation of SiC–SiO nanocomposite. The SiC–SiO 2 2 2 Keywords: layer on Si solar cells was found to be an excellent AR coating, exhibiting the low reﬂectance of 7.08% at Anti reﬂection coating wavelengths ranging from 400 to 1000 nm. The fabricated crystalline Si solar cell with SiC–SiO nanocom- SiC–SiO nanocomposite posite AR coating showed comparable power conversion efﬁciency of 16.99% to the conventional Si N x x p-Type silicon wafer AR coated Si solar cell. New and effective sol–gel derived SiC–SiO AR layer would offer a promising Sol–gel
