SOLAR CELL AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: The solar battery and manufacturing method thereof the contact area between the n-type semiconductor layer and the front electrode are increased and the charge collection rate can be improved. CONSTITUTION: The solar battery and manufacturing method thereof the semiconductor layer of the first conductivity type and semiconductor layer of the second conductive type, the trench(303) for the unit front electrode formation, and front electrode(304) is included. The semiconductor layer of the first conductivity type and semiconductor layer of the second conductive type are successively laminated.
