Abstract
TOPCon solar cells have significant advantages in cost and photoelectric conversion efficiency compared to other silicon-based solar cells,and are the main direction of development in the field of solar cells.First,this paper provides a detailed overview of the types of waste gas generated during the production process of TOPCon solar cells and PV modules,and analyzes the reasons for each type of waste gas.Then,the commonly used waste gas treatment methods in the PV industry are elaborated,and the advantages and disadvantages of each treatment method are listed.Finally,the current difficulties in waste gas treatment technology are analyzed,and the future development trends of waste gas treatment technology are discussed.The research results show that,according to the engineering treatment method,the waste gas generated during the production process of TOPCon solar cells and PV modules can be mainly classified into four categories:PECVD waste gas,acidic and alkaline waste gas,organic waste gas,and solid dust.Silane waste gas in PECVD waste gas is usually treated by direct combustion incinerator incineration.Among them,acidic and alkaline waste gas is usually treated with a two-stage acidic and alkaline waste gas purification tower for comprehensive acidic and alkaline recovery,organic waste gas is usually treated with activated carbon for physical adsorption,and solid dust is usually filtered using a bag filter.In the future,waste gas treatment technology will develop towards three directions:more efficient and environmentally friendly,intelligent,technology integration and innovation.关键词
