APPARATUS AND METHOD FOR SOLAR CELLS WITH LASER FIRED CONTACTS IN THERMALLY DIFFUSED DOPED REGIONS

摘要

This invention relates to an apparatus and a method for solar cells with laser fired contacts in thermally diffused doped regions. The cell includes a doped wafer and a plurality of first highly doped regions having a first conductivity type. The cell also includes a plurality of second highly doped regions having an opposite conductivity type from the first conductivity type and a passivation layer disposed over at least a portion of each the plurality of first highly doped regions and the plurality of second highly doped regions. The cell also includes a network of conductors having a first conductor and a second conductor, and a plurality of contacts electrically connecting the first highly doped regions with the first conductor and electrically connecting the second highly doped regions with the second conductor.
