Photovoltaic cells with a graded active region achieved using stamp transfer printing

Patent ·
OSTI ID:1440990

Disclosed herein are processes for fabricating organic photosensitive optoelectronic devices with a vertical compositionally graded organic active layer. The processes use either a single-stamp or double-stamp printing technique to transfer the vertical compositionally graded organic active layer from a starting substrate to a device layer.
