求翻译：光电池利用太阳能把电子从硅或其他材料中赶出来。被逐出的电子，由于带一个负电荷，而释放出该电子的那个原子带一个正电荷，所以，它们就流向不同的电极，从而产生出电流来。是什么意思？

The photovoltaic cells use solar energy electrons from the silicon or other materials, and driven out. Expelled electrons with a negative charge, and the release of the electrons that atom a positive charge, so they flow to the different electrodes, resulting in the current.
