Problems solved by technology

[0002] With the continuous development of the economy, energy and environmental issues have become important constraints on economic development. Solar energy, as a clean energy source, has been widely researched and applied all over the world. The production of solar cells mainly uses inorganic non-metallic materials, such as all-inorganic Perovskite materials are very suitable as absorbing layer materials in solar cells, but the three-dimensional structure of this material is unstable and prone to phase transition, which is not conducive to light absorption, which limits its application in optical devices
[0003] At present, in order to improve the stability of this material, it is usually covered with hydrophobic organic matter on the surface of this material or doped with other elements inside it. However, these two methods cannot fundamentally solve the problem of low material stability. Although the method of covering the surface with organic matter can isolate the material from water and oxygen in the air, once the organic matter on the surface falls off or the coverage is insufficient, water and oxygen will invade into the material, thereby causing the material to undergo a phase change and reducing the material’s durability. Stability. In addition, doping other elements can improve the stability of the material, but it will increase its band gap and reduce its light absorption ability, which is not conducive to the application in solar cells, and the added elements are also prone to oxidation. On the contrary, it will reduce the overall stability of the material.

Embodiment Construction

[0031] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0032] As in the background art, because the three-dimensional geometric structure of the material is prone to collapse, the structure is unstable, and the phase transition is prone to occur. The band gap gradually increases with the phase transition, which is not conducive to light absorption, and the surface modification method and the internal doping method cannot be based on the above. Solve the problem of unstable 3D geometry of materials.

[0033] In order to solve the above problems, the embodiments of the present invention provide an organic intercalation method, such as figure 1 As shown, the method includes:

[0034] 101. Obtain the three-dimensional geom...

Abstract

The invention discloses an organic intercalation method, device, material, testing method, application and solar panel, and relates to the field of materials, mainly in that the stability and photoelectric performance of the material can be improved, and the band gap of the material can be determined through the performance test conclusion. The width is adjusted to obtain a material that meets the band gap width requirements. The method includes: obtaining the three-dimensional geometric structure of the material; inserting organic molecules in the three-dimensional geometric structure according to the set number of inorganic layers, and reducing the three-dimensional geometric structure to a quasi-two-dimensional geometric structure; the organic molecules are used for Reduce the electronically effective mass of the material and / or increase the stability of the material. The present invention is applicable to the organic intercalation of materials.
