Embodiment Construction

[0028] In describing embodiments of the invention, specific terminology is used for the sake of clarity; however, the invention is not intended to be limited to the specific terminology so chosen; it is to be understood that each specific element encompasses all techniques that operate in a similar manner to accomplish a similar purpose equivalent.

[0029] The perovskite semiconductor material methylamine lead iodide (chemical formula CH 3 NH 3 PB 3 , that is, MAPbI 3 ) is currently a star material in new solar cells, which has the characteristics of cheap materials, simple preparation, and strong photoelectric conversion ability. The thin film reacts to form a pale yellow transparent complex MAPbI 3 ·xMA makes perovskite-type solar cell devices that can perform photoelectric conversion invalid. At the same time, the chemical reaction is very sensitive and the reaction speed is fast, which is suitable for the expanded application of monitoring sensors.

[0030] Therefore...

Abstract

The invention provides a methylamine monitor and a preparation method thereof. The methylamine monitor comprises a transparent electrode layer, a functional layer, a metal counter electrode layer andan external ampere meter, wherein the transparent electrode layer, the functional layer and the metal counter electrode layer are stacked in sequence, and areas of the transparent electrode layer, thefunctional layer and the metal counter electrode layer are sequentially reduced; the functional layer comprises an electron transfer layer and a perovskite active layer; and the perovskite active layer is stacked on the electron transfer layer. The methylamine can be rapidly monitored by the methylamine monitor, and the methylamine monitor is obvious in equipment change and is completely better than any other conventional methylamine monitoring device; and meanwhile, the metal counter electrode layer is capable of effectively extracting holes from the perovskite layer and exporting light current to an external circuit, the preparation process of the device is simplified, and the preparation cost of the device is reduced.

Description

technical field [0001] The invention belongs to the field of novel environmental protection and safety equipment, and in particular relates to a methylamine monitor and a preparation method thereof. Background technique [0002] Methylamine is a common organic compound with the chemical formula CH 3 NH 2 , is an important organic chemical industrial raw material, and is often used in the preparation of other chemicals in large quantities. Methylamine has strong biological toxicity and strong pungent smell, and it is very easy to cause dangers such as combustion and explosion when mixed with air. Due to the high usage of methylamine, if there are no effective safety measures and early warning equipment in the process of storage and transportation, it is easy to cause safety hazards. Many places in my country have reported the environmental hazards and personal and property losses caused by the leakage of methylamine. Therefore, it is of great significance to design a safe...
