摘　　要：热斑效应在太阳电池的实际应用中非常普遍,而且热斑效应严重影响太阳电池的性能和寿命,并有很大的危险性。研究热斑效应的影响因素,降低热斑效应危险性至关重要。根据热斑效应产生的现象,结合实验室所做的热斑试验经验,经过充足的相关试验验证,分析热斑效应的影响因素。分析发现热斑效应与温度有相当大的关系,影响热斑效应的内在因素主要有暗电流和内阻。The hot spot effect is very common in the application of solar cell, and the hot spot seriously affect the performance of solar cells and its service life with a great danger. So it＇s important to study the influence factors of the hot spot effect and reduce the risk of hot spot. The influence factors of the hot spot were analyzed according to the hot spot phenomenon. Combined with the hot spot test experiences in laboratory and the related experimental verifications, the analysis find that the hot spot and temperature have a considerable relationship, and the internal factors of hot spot mainly include the dark current and internal resistance.
