On page 7410, L. Beverina, S. Brovelli, and co‐workers demonstrate a new paradigm for fine tuning the phase segregation in small‐molecule solar cells based on the post‐deposition exploitation of latent hydrogen bonding. Thermally activating latent conjugated pigments fine‐tunes and stabilizes the nanoscale film connectivity, thereby simultaneously optimizing charge generation and transport processes, resulting in over 20‐fold increase of the photovoltaic efficiency.
