Description
Summary: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.
