为提高太阳电池及组件效率、提升光伏电站系统发电量,该研究主要从n型硅衬底材料特性出发,对比研究了三种不同n型电池的结构特点、研究进展及组件封装方案,并制备了双面组件样品,同时以p型PERC双面组件为对照组,通过理论模拟与现场实证的方法,研究了三种n型双面组件的发电能力。研究发现n型TOPCon双面组件的发电能力最高、IBC双面组件发电能力次之,双面率对组件发电能力具有一定的影响,封装材料对组件可靠性及发电能力影响的重要性,并分析预测n型双面组件将是未来光伏电站建设的首选产品。

In order to improve the efficiency of cells and modules and enhance the power generation of photovoltaic power station systems,the characteristics,research progress,and module encapsulating schemes of three different structures of n⁃type cells were compared and studied based on the characteristics of n⁃type silicon substrate materials.Double⁃sided module samples were produced,and the power generation capacity of three n⁃type double⁃sided modules was studied using theoretical simulation and on⁃site empirical methods,with p⁃type PERC double⁃sided modules as the control group.Research has found that n⁃type TOPCon double⁃sided modules have the highest power generation capacity,followed by IBC double⁃sided modules.The double⁃sided ratio has a certain impact on the power generation capacity of modules,and the importance of encapsulating materials on the reliability and power generation capacity of modules.It has been analyzed and predicted that n⁃type double⁃sided modules will be the preferred product for future photovoltaic power station construction.
