Normally, in a photovoltaic cell, electrons knocked free by photons are then carried away by an electric field within the photovoltaic material to a contact wire.
通常，在光伏芯片中，被光子激发的电子，在导电材料内部电场的作用下，通过导线定向移动。

The results indicate that many symmetry factors are the important reasons of the material transfer in electriccontact .
结果表明，接触过程中各种因素的不对称是产生材料转移的主要原因。
