Perovskite material for intelligent window, perovskite thermochromism method induced by polar solvent vapor and application of perovskite thermochromism method in intelligent device
The invention relates to the technical field of photothermal, in particular to a perovskite material for an intelligent window, a perovskite thermochromism method induced by polar solvent vapor and application of the perovskite thermochromism method in an intelligent device. The perovskite material for the intelligent window is an ABX3 type perovskite material, A comprises one or two of Rb and Cs, B is one or two of Sn and Pb, and X is one or more of Cl, Br and I. The invention further discloses a preparation method of the perovskite material for the intelligent window. The thermochromism method comprises the following steps: under the induction of polar solvent steam, the perovskite material is converted into a transparent colorless phase from a colored phase; under the action of thermal driving, the perovskite material is reversibly converted into a color phase from a transparent colorless phase. The thermochromism method has the characteristics of low transformation temperature, short transformation time, high visible light modulation capability, high reversible cycle index and good stability. When the method is applied to the intelligent window, rising of the indoor temperature can be effectively restrained, and the transformation temperature and time of the intelligent window are greatly reduced.
本发明涉及光热技术领域，尤其涉及一种智能窗用钙钛矿材料、极性溶剂蒸气诱导的钙钛矿热致变色方法及其在智能装置中的应用。智能窗用钙钛矿材料为ABX3型钙钛矿材料，其中，A包括Rb或Cs中的一种或两种，B为Sn或Pb中的一种或两种，X为Cl、Br或I中的一种或多种。热致变色方法包括在极性溶剂蒸气的诱导下，钙钛矿材料由彩色相转变为透明无色相；在热驱动作用下，钙钛矿材料由透明无色相可逆地转变为彩相。热致变色方法具有转变温度低、转变时间短、可见光调制能力高、可逆循环次数高和稳定性好的特点。将该方法应用于智能窗可以有效抑制室内温度的升高，并且大幅降低智能窗的转变温度和时间。
