  • SILVER-BISMUTH NON-CONTACT METALLIZATION PASTES FOR SILICON SOLAR CELLS
    Publication number: 20200098938
    Abstract: Metallization pastes for use with semiconductor devices are disclosed. The pastes contain silver particles, low-melting-point base-metal particles, organic vehicle, and optional crystallizing agents. Specific formulations have been developed that produce stratified metal films that contain less silver than conventional pastes and that have high peel strengths. Such pastes can be used to make high contact resistance metallization layers on silicon.

  • P-TYPE DOPING OF II-VI MATERIALS WITH RAPID VAPOR DEPOSITION USING RADICAL NITROGEN
    Publication number: 20150053259
    Abstract: Apparatus and methods to incorporate p-type dopants in II-VI semiconducting layers are disclosed herein. In some embodiments, radical nitrogen is introduced in a physical vapor deposition apparatus operating at moderate pressures (e.g. 10?5 Torr to 100 Torr). The radical nitrogen allows for in-situ doping of II-VI materials, such as ZnTe, to degenerate levels.
