Title: Edge coating apparatus for solar cell substrates

Abstract

A non-contact edge coating apparatus applies coating material to an edge of a non-circular solar cell substrate without physical contact. The apparatus may include a rotatable substrate support configured to hold the substrate. The apparatus may further include an applicator configured to receive a coating material and apply the coating material to an edge of the substrate while the substrate is rotated without any portion of the applicator physically touching the edge of the substrate. The substrate support may be mechanically coupled to a cam, which contacts a follower mechanically coupled to the applicator. A variety of coating materials may be employed with the apparatus including hot melt ink and UV curable plating resist.
