为节约能源,高转换率的晶体硅太阳能电池被广泛应用,而在低档片中黑心片占有很大的比例,本文对该类硅片进行测试、分析、查找原因,发现转换率低的主要原因是衬底含有大量的位错,形成少数载流子的强复合中心,严重影响硅片的少子寿命,最终影响电池转换率,发电量的减少.依据分析,为提高转换率,电池厂商应提出位错的供货标准,硅片厂商改善工艺方案.

In order to save energy,high conversion rate of crystalline silicon solar battery is widely used.The black heart wafer occupies a large proportion of low-grade wafer.In this paper,these silicon wafers are tested,analyzed and searched.There are lots of dislocations in the kind of wafers.Dislocation is the strong recombination center of minority carrier.This sriously affects minority-carrier lifetime lower than usually.Battery conversion rate is low.Power generation reduces.In order to improve the conversion rate,the battery manufacturer should put forward the dislocation supply standard.The silicon wafer manufacturer improves the production process.
