Abstract
The present disclosure provides multi-junction solar cell structures and fabrication methods thereof that improve electrical testing capability and reduce chip failure rates. In the present invention a special masking pattern is used in the layout such that all or some of the epitaxial layers are etched away in the corner areas of each solar cell. Consequently, the semiconductor substrate or one or more of the interconnections between junctions become accessible from the top (the side facing the sun) to make electrical connections.
