Abstract

A thin film type solar cell and a method for manufacturing the same are disclosed, the thin film type solar cell is capable of realizing the improved efficiency for the solar cell with a decreased dead zone, wherein the method comprises forming a plurality of front electrodes on a substrate, wherein the plurality of front electrodes are formed at fixed intervals by each first separating portion interposed in-between; forming a semiconductor layer and transparent conductive layer on an entire surface of the substrate including the front electrodes; forming a contact portion being in contact with the first separating portion by removing predetermined portions of the semiconductor layer and transparent conductive layer; forming a second separating portion by removing a predetermined portion of the transparent conductive layer; and forming a rear electrode connected with the front electrode through the contact portion.

Description

technical field [0001] The present invention relates to a solar cell, and more particularly, to a thin film type solar cell having a plurality of single cells connected in series. Background technique [0002] Solar cells with semiconducting properties convert light energy into electricity. [0003] The structure and principle of the solar cell according to the prior art will be briefly introduced below. A solar cell is formed in a PN junction structure in which a P-type semiconductor and an N-type semiconductor are combined. When sunlight is irradiated on the solar cell having the PN structure, holes (+) and electrons (-) are generated due to the energy of the sunlight. Since an electric field is generated in the region of the PN junction, holes (+) move to the P-type semiconductor, and electrons (-) move to the N-type semiconductor, thus forming a power source as the potential arises. [0004] Solar cells are mainly divided into silicon crystal solar cells and thin film...
