Abstract

In recent years, the progress of polymer solar cells (PSCs) has been greatly improved, with power conversion efficiencies (PCEs) exceeding 19%. In addition to major breakthroughs in the development of p-type and n-type materials, device engineering related to active layer morphology control plays a key role in improving efficiency. External treatments such as additives, thermal/solvent annealing, and interlayer modification are widely used to manipulate donor-acceptor bulk heterojunction (BHJ) layers. Volatile and non-volatile additives are considered to be a simple, efficient and effective method to control the morphology of active layers during spin-coating film-forming process. This review will summarize common and successful additives for fullerene and non-fullerene based PSCs.
