Because of the reflection on the back surface the minority carrier generation and illuminated surface photovoltage of both sides polishedwafer will be higher than one of single side polishedwafer.
由于背抛光面对受光面入射光的反射，使得少子产生率和受光面表面光电压都高于单面抛光片。

By splitting a laser beam and aiming each part onto opposite sides of a polished silicon wafer, the group engineered a system of reflection and interference that traps both beams in the silicon.
这组人员设计了一个反射和干涉系统，将激光分成两束，分别对准抛光硅晶片的两面，将两束光限制在硅当中。

Tetrahedral amorphous carbon (ta-C) films have been deposited on P-type (100) polished c-silicon wafer with different substrate negative bias by filtered cathodic vacuum arc technology.
