Light from an exotic crystal semiconductor could lead to better solar cells

This is a conceptual view of a transistor device that controls photoluminescence (the light red cone) emitted by a hybrid perovskite crystal (the red box) that is excited by a blue laser beam after voltage is applied to an electrode (the gate). Image: Vitaly Podzorov and Yaroslav Rodionov
