Multi‐Length‐Scale Morphologies Driven by Mixed Additives in Porphyrin‐Based Organic Photovoltaics

Abstract

A new category of deep-absorbing small molecules is developed. Optimized devices driven by mixed additives show a remarkable short-circuit current of ≈20 mA cm−2 and a highest power conversion efficiency of 9.06%. A multi-length-scale morphology is formed, which is fully characterized by resonant soft X-ray scattering, high-angle annular dark film image transmission electron microscopy, etc. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
