Abstract :
Stacked Ge dots are embedded in the intrinsic layer of Si-based PIN solar cells to improve the device performance. Relationship between structural parameters and photovoltaic properties is discussed through systematic variation of the repetition number of stacked Ge dots and Si spacer width to separate Ge dots.
