Description

Technical Field

[0001] The utility model relates to the technical field of perovskite preparation, in particular to a microwave reactor. Background Art

[0002] Perovskite refers to a type of ceramic oxide. Due to the many structural characteristics of this type of compound, it is widely used and studied in condensed matter physics. Therefore, physicists and chemists often refer to it by the ratio of the compounds in its molecular formula (1:1:3), so it is also called the "113 structure". It has a cubic crystal shape and often has stripes with parallel crystal edges. It is the result of polysynthetic twinning when the high-temperature variant transforms into a low-temperature variant. Perovskite materials have excellent semiconductor properties such as strong light absorption ability, adjustable band gap, high carrier mobility and long carrier diffusion distance. It has been widely used in various photovoltaic fields, especially in the field of perovskite solar cells. When using the temperature increase crystallization method to prepare perovskite, microwave reactors are one of the commonly used preparation equipment.

[0003] The existing perovskite preparation process has the following disadvantages: when using a microwave reactor to prepare perovskite, it is necessary to use microwaves to heat the perovskite precursor solution, and in order to ensure the preparation effect, a gradient heating method is generally adopted, which causes the perovskite preparation process to be time-consuming. In addition, since the existing microwave reactors are all independent structures, the single preparation amount is limited. For this reason, we propose a microwave reactor. Utility Model Content
