ABSTRACT:
The thicknesses of the intrinsic layers of the cells comprising a tandem photovoltaic device are selected so that the cell having the highest quality semiconductor material produces the lowest photocurrent. That cell will then be the dominant cell in the tandem device and its material properties will contribute disproportionately to the overall properties of the tandem device.
