Si quantum dots or interchangeably Si nanocrystals are promising materials for all-Si tandem solar cells in next generation photovoltaics. Si QDs in this study were fabricated by annealing sputtered Si rich oxide/SiO2 (SRO/SiO2) bilayer superlattice thin-films. Advantages of high Si content SRO layers include lower resistivity and higher light absorption cross-sections which are more suitable for...
