A Mechanistic Understanding of Processing Additive‐Induced Efficiency Enhancement in Bulk Heterojunction Organic Solar Cells. (31st October 2013) - Schmidt, Kristin
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.
