Abstract
Nanostructure array optoelectronic devices are disclosed. The optoelectronic device may be a multi junction solar cell. The optoelectronic device may have a bi-layer electrical interconnect that is physically and electrically connected to sidewalls of the array of nanostructures. The optoelectronic device may be operated as a multi junction solar cell, wherein each junction is associated with one portion of the device. The bi-layer electrical interconnect allows current to pass from one portion to the next. Thus, the bi-layer electrical interconnect may serve as a replacement for a tunnel junction, which is used in some conventional multi junction solar cells.
