The present invention provides a translucent solar cell and a manufacturing method thereof. The translucent solar cell comprises, in stacking order, a substrate, a first electrode layer, a photoconductive layer and a second electrode layer. The translucent solar cell is characterized in that there are formed a plurality of first light-transmissive apertures on the second electrode layer and the plurality of first light-transmissive apertures are further extended in a depth direction to the photoconductive layer to form a plurality of second light-transmissive apertures corresponding to the first light-transmissive apertures. A projected area of each of the second light-transmissive apertures is equal to or smaller than that of a corresponding first light-transmissive aperture.
