摘　　要：分别采用4种不同粒度(平均粒度为1.37、3.95、6.08和9.73μm)的铝粉制备单晶硅太阳能电池铝浆,研究铝粉粒度和烧结温度(800、830、850和870℃)对铝背场结深和光电转化率的影响。结果表明:采用不同粒度的铝粉在相同条件下制备的铝背场,经800℃烧结后,结深均为4.05μm左右,其中粒度为6.08μm的铝粉,其光电转化率最高,达到17.2%;烧结温度从800℃升高到870℃时,铝背场结深从4.05μm增加到4.75μm,转化率略有提高。Solar battery aluminum paste was preparaed using four different particle sizes（1.37,3.95,6.08,9.73 μm） of aluminum respectivly.The effects of particle size of aluminum and sintering temperature（800,830,850 and 870 ℃） on the junction depth of aluminum back surface field（BSF） and conversion rate of aluminum paste were studied.The results show that p-n junction depth of aluminum fabricated by different size aluminum powder is about 4.05 μm after sintered at 800 ℃.When the aluminum particle size is 6.08 μm,the maximum conversion efficiency value of 17.2% is obtianed.When sintering temperature increasing from 800 ℃ to 870 ℃,the p-n junction depth of BSF increases from 4.05 μm to 4.75 μm,the conversion rate of aluminum paste increases slightly.
