Electronic "Bucket Brigade" Could Boost Solar Cell Voltages

If solar cells could generate higher voltages when sunlight falls on them, they’d produce more electrical power more efficiently. Ferroelectrics - materials with an overall electrical polarization - can develop very high photovoltages under illumination. Berkeley Lab researchers have now figured out exactly how this photovoltaic process occurs.
