Improved solar cells

摘要

A method for making an organic photosensitive optoelectronic device capable of generating a voltage when exposed to light, the method comprising the steps of: (a) depositing a first organic layer over a first electrode; (b) depositing a second organic layer over the first organic layer; (c) depositing a metal cap confining layer over the second organic layer to form a stack; (d) annealing the stack; (e) removing the metal cap confining layer; and (f) depositing a second electrode over the second organic layer after step (e).
