Abstract

Disclosed are a solar battery module and a method for manufacturing the same. In the present invention, the solar battery module where solar batteries are connected in series comprises: a plurality of solar batteries which are arranged in rows and columns, and a conductive ribbon which electrically connects the solar batteries in series. The solar battery has a structure where a first photovoltaic device and a second photovoltaic device are stacked, wherein the first photovoltaic device comprises a polycrystalline semiconductor layer and the second photovoltaic device comprises an amorphous semiconductor layer.

Description

technical field [0001] The present invention relates to a solar cell module and a manufacturing method thereof, and more particularly, to a solar cell module formed by connecting solar cells in a tandem structure in which photoelectric elements are stacked in series, and to a manufacturing method thereof. Background technique [0002] Conventional general solar cells are single-junction type, and therefore, large-area solar cells are required in order to generate a large amount of electric power. However, such an increase in area imposes restrictions on the installation place and the like, leading to an increase in cost. [0003] In addition, even in the case of a solar cell with the highest photoelectric conversion efficiency in a single-junction solar cell, it is only about 20%, and most of the light is directly transmitted or reflected and disappears. [0004] In order to overcome the above-mentioned problems, solar cells with a double-junction tandem structure in which ...
