太阳能电池工作原理简介

当太阳光照射p-n结时，在半导体内的电子由于获得了光能而释放电子，相应地便产生了电子——空穴对，并在势垒电场的作用下，电子被驱向n型区，空穴被驱向P型区，从而使凡区有过剩的电子，P区有过剩的空穴。于是，就在p-n结的附近形成了与势垒电场方向相反的光生电场。

Introduction of Solar Cells Work

When the sunlight when the p-n junction,in the semiconductor electronic access to the light as a result of the release of e-,have given rise to a corresponding e-hole pairs.Electric field in the barrier under,e-to be expelled to the n-type area,hole to be expelled to the p-type area,so that there are excess n e,p area of the hole excess.Thus,in the p-n junction near the barrier electric field with opposite direction of the photovoltaic field.
