摘要(Abstract)：

以p型直拉PERC单晶硅太阳电池为研究对象,研究了电注入退火在不同的电流、时间和温度条件下,电注入退火前、后太阳电池的各项电性能参数的变化,以及经过5 kWh光致衰减(LID)实验后电池电性能参数的变化,实验均采用Halm电学性能测试仪进行测试和分析。结果表明,在目前的电注入设备条件下,以6.0A的电流在180℃温度下处理35min,最有利于p型直拉PERC单晶硅太阳电池由衰减态向再生态转变;电注入退火后,电池转换效率提升了0.8%;在经过5 kWh LID后,电池的转换效率相对于初始值仅降低了0.71%,证明电注入退火可有效降低p型直拉PERC单晶硅太阳电池的LID效应。
