Perovskite solar cells

Switchable photovoltaics

Nature Materials volume 14, pages 140141 (2015) | Download Citation

The migration of ions under the effect of an external electric field locally modifies the doping of organometal halide perovskite films. This is used to reversibly switch the photocurrent direction in very simple photovoltaic architectures.
