Translucent solar cell and manufacturing method thereof

摘要

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.

1. A translucent solar cell, consisting of, in order of stacking, a substrate, a first electrode layer, a photoconductive layer and a second electrode layer;
wherein the photoconductive layer is a single layer structure; wherein a plurality of first light-transmissive apertures are formed 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; wherein a projected area of each of the second light-transmissive apertures is smaller than that of a corresponding first light-transmissive aperture such that short-circuits between the first electrode layer, the photoconductive layer and the second electrode layer are avoided; wherein the second light-transmissive apertures are further extended in the depth direction to the first electrode layer so as to form a plurality of third light-transmissive apertures directly abutted against the substrate, wherein the projected area of the third light-transmissive apertures is equal to that of the second light-transmissive apertures; wherein the first electrode layer and the second electrode layer comprise a transparent conductive oxide selected from the group consisting of SnO2, ITO, ZnO, AZO, GZO, and IZO respectively.
