Abstract

Fullerene Intercalation In article number 1900508, Tobias Unruh and co-workers report on the formation process of a PC60BM:pBTTT-C14 active layer of a bulk heterojunction organic photovoltaic solar cell during evaporation of the solvent:additive mixture. By careful evaluation of the in-situ grazing incidence small-angle X-ray scattering measurements, a conclusive picture of the 5-step mechanism of fullerene intercalation and additive-tuned evolution of the nanoscopic film structure during the drying process could be obtained.
