【摘要】 以Bi2O3、B2O3和ZnO为主要原料,制备了一种导电铝浆用无铅玻璃粉。利用XRD、DTA和SEM对所得玻璃粉进行了表征。结果表明,玻璃粉结构主要为非晶态,软化点在500℃左右,粒径小于5μm。以此玻璃粉为原料制备了一系列玻璃粉含量不同的导电铝浆,并将其印刷到太阳能电池片上,检测了太阳能电池片的性能。结果表明:玻璃粉含量为1%时,电池片铝膜电阻率最小;玻璃粉含量减少时,电池片耐水煮性能有所提升。更多还原

【Abstract】 A kind of Bi2O3-B2O3-ZnO Pb-free glass frits for Al paste was prepared,using Bi2O3,B2O3 and ZnO as main starting material.The as-prepared glass powder was characterized by X-ray diffraction(XRD),differential thermal analysis(DTA)and scanning electron microscope(SEM).Results showed that the glass powder was amorphous in majority,the softening point was about 500℃ and the mean grain size was less than 5μm.A series of solar cells were manufactured using Al paste by varying the content of glass powder in the Al paste,and their performance were tested.The results showed that when the content of glass powder in Al paste was 1%,the aluminum coating resistivity was lowest,and the boiling water resistance was improved with the decrease of the content of glass powder in Al paste.更多还原
