The invention belongs to the field of liquid disinfection methods, and particularly relates to an ultraviolet-ozone combined disinfection method for a soil-less culture nutrient solution. The method comprises the following steps: (1) a liquid to be disinfected in a nutrient solution pool flows into a pipeline through the power provided by a water pump; (2) the nutrient solution enters a filter for filtration; (3) the filtered nutrient solution flows into a Venturi tube ejector and is mixed with ozone generated by an ozone generator to kill pathogenicbacteria by utilizing the strong oxidizing property of the ozone; (4) the nutrient solution which is sterilized by the ozone flows into an ultraviolet disinfector to further kill microorganisms which are not killed by the disinfection of the ozone; and (5) the sterilized nutrient solution flows out of a liquid outlet of the ultraviolet disinfector and enters a liquid storage tank to finish the whole disinfection process. The nutrient solution greatly improves the sterilization effect through the filtration of the filter, the disinfection of the ozone and the disinfection of ultraviolet rays, and ensures that the quantity of the microorganisms in the nutrient solution is minimized; and the complete set of device has the advantages of low cost, small energy consumption, and expense economization.

The invention discloses a preparation method of a perovskite solar cell based on a nickel oxide hole transport layer. The core innovation of the preparation method is to add an ultraviolet ozone surface treatment technology in the preparation step of a hole transport layer. The problem that the thickness is not uniform and holes can be generated easily for a nickel oxide hole transport layer prepared by spin coating is solved, and the perovskite film in the device is prevented from directly contacting a transparent electrode to affect the performance of the device. Compared with the method ofmodifying a nickel oxide film by doping nanoparticles, a perovskite solar cell prepared by the method of the invention is more stable, and the difference between the devices prepared by the method issmaller.
