Discussion on the Environmental Impact of N-type Photovoltaic Cell Project Under the New Process
N-type photovoltaic cells mainly include TOPCon and HJT two types,which have complex production processes,but due to the higher conversion efficiency,they have become the mainstream direction of the development of photovoltaic cells,and their impact on the environment has gradually become the focus of people′s attention.Through the analysis of TOPCon and HJT two types of photovoltaic cell production processes,this paper sorts out the pollutants generated and discharged by each production process,focuses on the analysis of the impact of the change of the strong acid on the emissions of nitrogen oxides and other emissions,the impact of changes in raw and auxiliary materials on environmental risks,the change of the exhaust gas treatment process on the impact of the efficiency of atmospheric pollutants treatment.It points out the contents of existing environmental impact assessment of photovoltaic cell projects which are not applicable to the new process in the relevant technical specifications,and gives the solutions.
