Conjugated polymer blends for high efficiency organic solar cells

Abstract:

The invention relates to a process for producing a conjugated polymer blend. The process for producing the conjugated polymer blend comprises the mixture of: a polymer A (X-Y), where X is ##STR00001## and Y is ##STR00002## and h is a substituent, a polymer B (X-Y') where X is ##STR00003## Y' is ##STR00004## and j is a substituent, and an acceptor. In this process h and j are different substituents and independently selected from each other.
