Patent ID: 8324012

Claim:
A fabricating method of a tandem solar cell, the steps comprising: providing a top inverted solar cell having a plurality of inverted solar sub-cells; providing a bottom normal solar cell having a plurality of normal solar sub-cells corresponding with the inverted solar sub-cells; and executing a pressing fit process of said top inverted solar cell and said bottom normal solar cell; wherein an interlayer and an anti-reflux protective device for preventing reflux occurrence are set between said bottom normal solar cell and said top inverted solar cell in said pressing fit process, wherein said interlayer includes a plurality of conductive dots, and said plurality of inverted solar sub-cells and said plurality of normal solar sub-cells are placed with an offset distance from each other, a solar sub-cell is formed after said pressing fit process of said inverted solar sub-cell and said normal solar sub-cell, and plurality of said solar sub-cell for series/parallel connection by said plurality of conductive dots.
