When a backward biasingvoltage is applied, the thickness of a depletion layer formed is made large, so that generation of hot carriers is minimized.
当施加反向偏置电压时，形成的耗尽层厚度变大，从而使热载流子的产生减到最小。

It is known from the experiment that, by using external biasingvoltage, the separation of photoelectrons from vacancies can be effectively promoted and the degradation efficiency is further improved.
通过实验可知，使用外加偏电压可以有效地促进光生电子和空穴的分离，进一步提高降解效率。
