boron concentration meaning in Chinese

硼浓度

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。
With superior properties such as high thermal conductivity , high hole mobility , excellent chemical , thermal and radioactive stability , p - type diamond electrode can also greatly improve the stability of the devices , which complement the current electrode . the effect of boron concentration on the electronic properties of diamond films was investigated by raman spectroscopy , x - ray photoelectron spectroscopy and
结果表明，掺杂金刚石膜突出的光学及电学性质及优异的抗高温、抗腐蚀能力，机械强度大等优点，使其在作lppp发光器件的电极时，能克服一般电极在空气中易于氧化、稳定性差的缺点，大大改善器件稳定性，提高器件寿命。
