The invention belongs to the technical field of solar cells, and relates to a preparation method, a product and application of a strong-polarity tin oxide nano material. A Meerwein reagent is used for carrying out ligand modification on an organic amine and organic acid modified SnO2 nano material to obtain a nano material modified by one or more ligands of tetrafluoroborate BF4 <->, Me3O <-> and Et3O <->, so that the nano material can be dispersed in a strong-polarity organic solvent and then is spin-coated or blade-coated on an ITO / FTO (indium tin oxide / fluorine-doped tin oxide) substrate or a perovskite layer; the obtained tin oxide film has relatively good conductivity and leveling property, excellent film-forming property and relatively good spreadability; meanwhile, the tin oxide organic strong-polarity dispersion liquid has long-term stability in the aspect of storage stability; and the material has excellent light conversion efficiency in the aspect of device performance.

This invention relates to the field of pipeline temperature control switch technology, and more particularly to a temperature control valve, comprising a valve body, a valve core, a temperature control unit, and a drive device. The valve body has an inlet channel and an outlet channel separated by a partition, and the partition has a connecting port. The valve core includes a push block positioned above the connecting port, with multiple arc teeth on its lower part. The output end of the drive device is connected to the push block. A sleeve is provided on the push block, with one end of a rotating rod connected to the output end of a drive motor, and the other end threadedly connected to the sleeve. The drive device causes the push block to gradually move towards the connecting port, and the lower part of the arc teeth gradually enters the connecting port. Water flowing through the connecting port exits through the channel between two arc teeth. Multiple channels between adjacent arc teeth form a multi-channel structure, reducing pressure loss and side leakage, greatly improving the performance of this temperature control valve. The threaded connection allows for more precise control of the channel opening size and flow rate ratio, resulting in more accurate temperature control.
