Abstract:In this study, we present the effect of annealing time on the power conversion efficiency (PCE) of silicon nanowire (SiNW) based solar cell prepared by wet diffusion technique. P-typed SiNW arrays were prepared by metal assisted chemical etching (MACE) method using aqueous solution including HF (4.6 M) and AgNO3 (0.02 M). The prepared SiNWs have V-shaped structures with the wall thickness in a range from 10-50 nm and the average length of 1.5 m. The reflectance of SiNW array remained less than 20 % and lower … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
