An amorphous silicon layer is built on and adhered to the crystalline silicon substrate of the solar cell at low temperature.
The adherence with low temperature realizes the thin substrate of cell, thus reducing the silicon used by 17.5%.
The originality of making the most of the both merits of the single crystal silicon and amorphous silicon, and high technological development ability which helped realize the industry's top conversion efficiency for the cell and module (17.3% and 15.2% respectively) are highly acclaimed.
