SOLAR CELL, SOLAR CELL SYSTEM, AND METHOD FOR MAKING THE SAME

摘要

A solar cell includes a first electrode layer, a P-type silicon layer, an N-type silicon layer, and a second electrode layer. The first electrode layer, the P-type silicon layer, the N-type silicon layer, and the second electrode layer are arranged in series side by side along a straight line and in contact with each other, thereby cooperatively forming a planar structure. The planar structure has a photoreceptive surface substantially parallel to the straight line and directly receives an incident light. A P-N junction is formed near an interface between the P-type silicon layer and the N-type silicon layer.
