  • Method for stabilizing dendritic web crystal growth
    Patent number: 6626993
    Abstract: A process for dendritic web growth is described. The process includes providing a melt, growing a dendritic web crystal from the melt, replenishing the melt during the step of growing the dendritic web crystal, and applying a magnetic field to the melt during the step of growing the dendritic web crystal. An apparatus for stabilizing dendritic web growth is also described. The apparatus includes a crucible including a feed compartment for receiving pellets to facilitate melt replenishment and a growth compartment designed to hold a melt for dendritic web growth. The apparatus further includes a magnetic field generator configured to provide a magnetic field during dendritic web growth.

  • System and method for dendritic web solar cell shingling
    Publication number: 20030121228
    Abstract: A dendritic web solar cell shingled array comprises at least two dendritic web solar cells. A first cell overlaps a portion of a second cell such that a back contact of the first cells interconnects with a top contact of the second cell. The cells are less than 150 microns thick, allowing a direct connection between the back contact and top contact of the two cells without the use of a visible busbar. The cells may be shingled together using soldering material and/or electrically conductive adhesives.
