A mechanistic understanding of processing additive-induced efficiency enhancementin bulk heterojunction organic solar cells

Keywords

Heterojunction organic solar cell

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.
