摘要：
A solar cell having n-type and p-type interdigitated back contacts (IBCs), which cover the entire back surface of the absorber layer. The spatial separation of the IBCs is in a direction perpendicular to the back surface, thus providing borderless contacts having a zero-footprint separation. As the contacts are on the back, photons incident on the cell's front surface can be absorbed without any shadowing.
