A solar cell is disclosed, including the following elements. A through hole passes through a substrate, wherein the substrate includes a third surface in the through hole. A first thin film semiconductor layer is disposed on the third surface in the through hole and extended to be over the second surface of the substrate, wherein the first thin film semiconductor layer is second type. A second thin film semiconductor layer is disposed on the first surface of the substrate. A through hole connection layer is disposed in the through hole and extended to be over the first surface and the second surface of the substrate, wherein a junction is formed between the first thin film semiconductor layer and the substrate to prevent shorts from occurring between the through hole connection layer and the substrate.
