摘　　要：利用铝背场材料水煮特性的差异性,对4种铝背场多晶太阳能电池片的水煮特性进行了研究,详细分析了4种不同铝背场电池片老化特性(冷-热循环特性和湿热特性)与水煮特性的关系,同时也探讨了单晶与多晶电池片老化特性的差异性。结果表明:铝背场水煮特性较好的电池片表现出较好的湿热老化特性,但电池片的冷-热循环老化特性与其水煮特性无直接关系;单晶电池老化特性略优于多晶,且冷-热循环约40周后电池效率衰减基本稳定,湿热老化450~500 h后电池效率衰减基本稳定。Used the difference of boiling characteristics of aluminum back surface field （Al-BSF） materials, the boiling characteristics of four different Al-BSF polycrystalline solar cells were studied. The relationship between their aging characteristics （cold-thermal cycling characteristics and hygrothermal characteristics） and boiling characteristics was analyzed. The differences of aging characteristics between the monocrystalline silicon solar cell and the polycrystalline were also discussed. And the results show that the cell with better boiling characteristics behaves better damp heat aging properties. However, the cold-thermal cycling characteristics of the cell is not directly related to its boiling characteristics. The aging characteristics of monocrystalline solar cell are slightly superior to those of polycrystalline solar cell. After about 40 cycles of cold-thermal cycle or 450-500 h of hygrothermal aging, the efficiency decay of cell is basically stable.
