Abstract
A reverse mode light valve, the manufacture of a light control device and a method of controlling light transmittance by using of the reverse mode light valve, the reverse mode light valve containing ABXperovskite particles () suspended in a liquid suspension () can control light transmittance in a higher light transmittance when the power is turned off (OFF state) and lower light transmittance when the power is turned on (ON state). In the ABXperovskite particles (), A is at least one of Cs, CHNH, and Rb, B is at least one of Pb, Ge, and Sn, and X is at least one of Cl, Br, and I.
