We designed a novel wrap-around metal contact that does not require a TCO film; consequently, the ρc of the wrap-around Si/Ag contacts was drastically decreased in comparison with conventional Si/ITO contacts. In addition, we were able to adjust the contact area during the fabrication process in order to vary Rc. Using the top metal contacts wraparound design resulted in a high fill factor of ~65.4%.
