Technology

Ion implantation and laser processing technologies are very attractive for the fabrication of industrially feasible interdigitated back-contact (IBC) solar cells. In this work, p(+) emitters were fabricated by boron implantation and laser annealing, and the electrical properties of emitters were investigated. An emitter sheet resistance (R-sh) in the range of 30-200 Omega/square could be achieved by varying the implanted dose. The saturation current density (J(oe)) of the passivated p(+) emitter with R-sh of similar to 125 Omega/square reached 95 fA/cm(2), and the contact resistivity was determined to be as low as 5x10(-6) Omega.cm(2). Such localized p(+) emitters can be applied to n-type IBC solar cells, which could avoid the high temperature thermal annealing step and related problems. (C) 2014 Published by Elsevier Ltd.
