Abstract

A pn junction solar cell includes a pn junction structure including a p-type and a n-type semiconducting layer, a front contact electrode formed on the front surface of the pn junction structure through a contact pattern having a constant width, and a rear contact electrode formed on a rear surface of the pn structure. The front contact electrode is reduced in its width as it goes away from a terminal.
