  • Patent number: 9620661
    Abstract: Approaches for foil-based metallization of solar cells and the resulting solar cells are described. For example, a method of fabricating a solar cell involves locating a metal foil above a plurality of alternating N-type and P-type semiconductor regions disposed in or above a substrate. The method also involves laser welding the metal foil to the alternating N-type and P-type semiconductor regions. The method also involves patterning the metal foil by laser ablating through at least a portion of the metal foil at regions in alignment with locations between the alternating N-type and P-type semiconductor regions. The laser welding and the patterning are performed at the same time.

    Abstract: A press pack module includes a collector module terminal, an emitter module terminal, a gate module terminal, and an auxiliary module terminal. Each IGBT cassette within the module includes a set of shims, two contact pins, and an IGBT die. The first contact pin provides part of a first electrical connection between the gate module terminal and the IGBT gate pad. The second contact pin provides part of a second electrical connection between the auxiliary module terminal and a shim that in turn contacts the IGBT emitter pad. The electrical connection between the auxiliary emitter terminal and each emitter pad of the many IGBTs is a balanced impedance network. The balanced network is not part of the high current path through the module. By supplying a gate drive signal between the gate and auxiliary emitter terminals, simultaneous IGBT turn off in high speed and high current switching conditions is facilitated.
