Perovskite microcells for solar windows
Developed by Korean scientists through a novel lift-off-based patterning approach based on swelling-induced crack propagation, the perovskite PV device achieved an open-circuit voltage of 1.16 V, a short-circuit current density of 22.5 mA/cm2, and a fill factor of 77%. With the microcells, the researchers also built a first prototype of a solar window which they claim has vivid colors and high color purity.
