Solar Cells: Spin-Cast Bulk Heterojunction Solar Cells: A Dynamical Investigation Print
Wednesday, 03 April 2013 13:32

Spin-coating is extensively used in the lab-based manufacturing of organic solar cells, including most of the record-setting cells. Aram Amassian and co-workers report in this study 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 scaling up production.
