| 5. | In order to avoid light degradation , low interstitial oxygen content and low boron concentration b - doped p - type cz - si material should be used , for example , the resistivity can be from 5 - 10 . cm , the efficiency has reached to 22 . 0 % 上述研究工作表明:为了避免光衰减,提高硅片少子寿命,应该选择低氧浓度的硅片,并降低硼的掺杂浓度,即:使用高阻材料制作太阳电池。 |
| 6. | Moreover , concentrations of interstitial oxygen in samples changed after fast neutron irradiation . the interstitial oxygen concentration of the samples decreased with increasing of irradiation dosage . this result can be explained in terms of higher generation rates of ( v - o ) complex 另外,快中子辐照对于直拉硅的间隙氧含量有很大影响,间隙氧含量随着辐照剂量的增加而减少,这主要归于样品中产生了大量的( v - o )复合体。 |
| 7. | In this part , the issues and mechanism of light degradation of b - doped p - type cz - si solar cells are introduced firstly , it was clarified that boron and interstitial oxygen are major components of defect center for light degradation of b - doped cz - si solar cells . then in the experiment the b - doped cz - si is chosen as the substrates and annealled at different temperature 文中首先介绍了掺硼单晶硅太阳电池的光照衰减问题及衰减机制,然后以p型掺硼单晶硅为实验样品,经过不同温度的热处理,对影响光衰减的主要因素硼、氧进行了研究。 |
| 8. | After annealing at 600 , because of formation of multi - vacancy - type defects that have long positron lifetime , positron annihilation average lifetime increased . when the average positron lifetime increased to maximum value ( 360ps ) , the interstitial oxygen concentration decreased to minimum value ( 4 1017atoms / cm3 ) . this result suggested that oxygen was involved in the formation of multi - vacancy - type defects 正电子湮没技术测试证明,快中子辐照直拉硅中在大约600退火时产生的多空位缺陷具有较长正电子寿命,可以使正电子平均寿命增加,当样品的正电子平均寿命达到最大时( 360ps ) ,其间隙氧含量降到一个极小值( 4 10 ~ ( 17 ) atoms / cm ~ 3 ) ,这说明氧参与了这些缺陷的形成。 |
