METHOD FOR THE MANUFACTURE OF IMPROVED EFFICIENT TANDEM PHOTOVOLTAIC DEVICE AND DEVICE MANUFACTURED THEREBY

摘要

The thicknesses of the intrinsic layers (20a, 20b, 20c) of the cells (18a, 18b, 18c) comprising a tandem photovoltaic device (10) 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.
