Abstract
Abstract A solar battery is manufactured by forming individual cells in a wafer, mounting the wafer on a substrate and separating the cells by the use of a thin saw. The channel thus formed between the cells is filled with an insulating material to prevent the accidental entry of stray material which might result in unwanted conduction between the cells. Preferably the insulating material between the cells is the same color as the cells in the interest of enhanced appearance.
