Abstract
The present invention discloses a tandem solar cell and fabricating method thereof. The fabricating method comprises: a top inverted solar cell having a plurality of inverted solar sub-cells is provided; a bottom normal solar cell having a plurality of normal solar sub-cells accompanying with the inverted solar sub-cells; and pressing fit the top inverted solar cell and the bottom normal solar cell, wherein an interlayer is set between the bottom normal solar cell and the top inverted solar cell in the pressing fit process, wherein the interlayer includes a plurality of conducting dots, and the plurality of inverted solar sub-cells and normal solar sub-cells are placed with a distance each other; a solar sub-cell is formed after pressing fit the inverted solar sub-cell and the normal solar sub-cell, and the plurality of solar sub-cells are series/parallel connection each other by electrically connected the plurality of conducting dots.
