Abstract:
1. A method for manufacturing three-terminal solar cell array, comprising: sequentially forming a first transparent conductive layer, a first semiconductor layer, a second transparent conductive layer, a second semiconductor layer, and a third conductive layer on a transparent substrate; forming a first opening in the third conductive layer, the second semiconductor layer, the second transparent conductive layer, and the first semiconductor layer to expose the first transparent conductive layer; forming a second opening in the third conductive layer and the second semiconductor layer to expose the second transparent conductive layer; forming third openings in the third conductive layer, the second semiconductor layer, the second transparent conductive layer, the first semiconductor layer, and the first transparent conductive layer to expose the transparent substrate, wherein the extending direction of the third openings is perpendicular to the extending direction of the first opening and the second opening to isolate individual solar cells; forming a conformal dielectric layer on the upper surface of the solar cells and the transparent substrate; forming a fourth opening, a fifth opening, and a sixth opening to respectively expose the first transparent conductive layer, the second transparent conductive layer, and the third conductive layer by etching the dielectric layer; and forming a first metal line, a second metal line, and a third metal line respectively in the fourth, fifth, and sixth openings to directly connect the first transparent conductive layer, the second transparent conductive layer, and the third conductive layer.
