Title:
A mechanistic understanding of processing additive-induced efficiency enhancement in bulk heterojunction organic solar cells

Abstract:
The addition of processing additives is a widely used approach to increase power conversion efficiencies for many organic solar cells. We present how additives change the polymer conformation in the casting solution leading to a more intermixed phase-segregated network structure of the active layer which in turn results in a 5-fold enhancement in efficiency. © 2013 WILEY-VCH Verlag GmbH & Co.
