Abstract
A method and apparatus for fabricating large scale PV cell and solar module/panel is disclosed. The method includes designing a PV cell wiring scheme for a number of PV cells and patterning a plurality of features on a large size silicon sheet. A number of large scale silicon sheets, having a number of PV cells on each silicon sheet, can be bonded to a wiring plane to directly manufacture into a solar module/panel. Each PV cell on the solar module is then isolated. Methods of the invention greatly cut down the cost of solar module/panel manufacturing and PV cell assembly.
