defect center meaning in Chinese
故障中心
缺陷中心
Examples
- 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。 - As a result 4 the rising annealing temperature induces si02 phase to form , also ivolves the formation of a si phase . in high - temperature - annealed sio ~ , films the excess silicon atoms are present as si - si4 tetrahedra , randomly dispersed in the amorphous si02 matrix . photoluminescent spectra were observed for the samples excided by the laser whose wavelength is 365nm . the pl peak is located at about 445nm , which dose n ' t shift as the annealing temperature changes . as the annealing temperature is raised , the luminescent intensity increases . the phenomena suggest that the si - o - si bond as a defect center which is broken down by the stress at the si nc / si02 interface is the primary source of blue luminescence
这个陡的界面由于明显的晶格结构的差别而有较大的应力。界面的形成伴随着界面发光中心的增加，同时pl强度在l户800有一个大的增强。这个结果提示我们，界面上h 0 s工键断裂形成的nbohc应是蓝光发射的主要原因。
