MULTIJUNCTION SOLAR CELL HAVING ELECTRIC CURRENT MATCHING STRUCTURE

摘要

PURPOSE: A multi-junction solar cell having an electric current matching structure is provided to increase the generation of current by using cells and apertures. CONSTITUTION: A second solar cell(103) is formed on a substrate. A first solar cell(105) is formed on the second solar cell. An aperture part(201) sends sunlight to the second solar cell. The aperture part is formed in a part of the first solar cell. The aperture part penetrates from the first solar cell to the second solar cell. [Reference numerals] (AA) Sunlight
