25_13/2013Solar Cells: Spin-Cast Bulk Heterojunction Solar Cells: A Dynamical Investigation (Adv. Mater. 13/2013)

Spin-coating is extensively used in the lab-based manufacture of organic solar cells, including most of the record-setting cells. Aram Amassian and co-workers report on p. 1923 the first direct observation of photoactive layer formation as it occurs during spin-coating. The study provides new insight into mechanisms and kinetics of bulk heterojunction formation, which may be crucial for successful transfer to printing processes and scale-up.
