Abstract:
1. A method for forming a solar cell device, comprising: forming a solar cell element including a plurality of solar cell terminals in a semiconductor structure; forming a metal oxide semiconductor (MOS)-based transistor switch in the semiconductor structure; integrating the transistor switch with an N-type solar cell terminal, which constitutes a first N region of the solar cell element, of the plurality of solar cell terminals; forming a source region of the MOS-based transistor switch within a second N region of a solar cell within the solar cell element; forming the source region in a p-type region that is in direct physical contact with the second N region of the solar cell; forming the N-type solar cell terminal in direct physical contact with the second N region of the solar cell and an external contact of the solar cell; and forming an electrical connection between the solar cell element and the MOS-based transistor switch.
