Abstract

Disclosed is a solar cell including: an upper substrate and a lower substrate facing each other; a semiconductor layer on a predetermined region of the lower substrate; out the pattern. Various patterns are formed between the upper substrate and the lower substrate so as to increase the contact area of ​​the bonding member provided between the upper substrate and the lower substrate, thereby improving the connection between the upper substrate and the lower substrate. Adhesion between the lower substrates.

Description

Technical field [0001] The embodiment relates to a solar cell. Background technique [0002] Generally, solar cells convert solar energy into electrical energy. Recently, with the increase in energy consumption, solar cells have been widely used for commercial purposes. [0003] According to the related art, a solar cell is manufactured by sequentially laminating a back electrode layer, a light absorption layer, a transparent electrode layer, and an upper substrate on a lower substrate, wherein the upper substrate is horizontally bonded to the uppermost end of the solar cell. [0004] However, because only one bonding member is provided between the upper substrate and the lower substrate, the bonding force between the upper and lower substrates is limited, and the reliability of preventing moisture penetration becomes poor. Summary of the invention [0005] technical problem [0006] The embodiment provides a solar cell that can improve the adhesion between the upper substrate and th...
