SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

A solar cell includes a p-n structure having a first conductive semiconductor substrate, a second conductive semiconductor layer formed on the first conductive semiconductor substrate and having a conduction opposite to the first conductive semiconductor substrate, and a p-n junction formed at an interface between the first and second conductive semiconductor substrate/layer; a first anti-reflection film formed on the second conductive semiconductor layer and composed of SiNx:H thin film with 40-100 nm thickness; a second anti-reflection film formed on the first anti-reflection film and composed of silicon oxy-nitride; a front electrode formed on the second anti-reflection film in a predetermined pattern and connected to the second conductive semiconductor layer through the first and second anti-reflection films; and a rear electrode formed at an opposite side to the front electrode with the first conductive semiconductor substrate being interposed therebetween to be connected to the first conductive semiconductor substrate.
