A solar cell hollow circuit is provided. The solar cell hollow circuit includes a substrate, a first conductive layer, a photoelectric conversion layer and a second conductive layer. The first conductive layer is formed on the substrate. The photoelectric conversion layer is formed on the first conductive layer. The second conductive layer is formed on the photoelectric conversion layer. A hollow surround area is formed on the substrate by the first conductive layer, the photoelectric conversion layer and the second conductive layer. The hollow surround area defines an opening and a positive contact or a negative contact corresponding to the opening.
