摘要：
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 ABX3 perovskite particles (200) suspended in a liquid suspension (300) 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 ABX3 perovskite particles (200), A is at least one of Cs+, CH3NH3+, and Rb+, B is at least one of Pb2+, Ge2+, and Sn2+, and X is at least one of Cl−, Br−, and I−.
