Superior optical properties of Si-nanocrystals (Si-NCs) compared with bulk Si, particularly tunability of bandgap by controlling size, can be exploited for realizing next-generation Si tandem solar cells. In view of this, optical bandgap tunability of Si-NCs fabricated by Inductively Coupled Plasma Enhanced Chemical Vapor Deposition (ICPCVD) is presented. The SiOx<;2/SiO2 superlattice approach was used for realizing Si-NCs with tight size control. Deposition time of SiOx sublayer and, hence… CONTINUE READING
