A tandem solar cell module includes a transparent substrate, a first solar cell unit, and a second solar cell unit disposed between the transparent substrate and the first solar cell unit. The first solar cell unit includes a first electrode, a second electrode, and a first absorption layer disposed between the first electrode and the second electrode, and the second solar cell unit includes a third electrode, a fourth electrode, and a second absorption layer disposed between the third electrode and the fourth electrode, wherein the second electrode is located adjacent to the third electrode, and the positions of the second electrode, the third electrode, and the fourth electrode are corresponding to each other.

A method for fabricating an integrated AC LED module comprises steps: forming a junction layer on a substrate, and defining a first growth area and a second growth area on the junction layer; respectively growing a Schottky diode and a LED on the first growth area and the second growth area; forming a passivation layer and a metallic layer on the Schottky diode, the LED and the substrate. Thereby, the Schottky diode is electrically connected with the LED via the metallic layer. Thus is promoted the reliability of electric connection of diodes, reduced the layout area of the module, and decreased the fabrication cost.
