Abstract: Solar cell module and method of making same, characterized by a plurality of solar cell discs or wafers first disposed between opposite faces of an electrically insulating sheet of the same thickness as the wafers, and thence printed on both sides with electrical conducting material to provide a positive conducting face on one side of all wafers and integral solderless printed conductors between adjacent wafers and a negative grid on the other side of all wafers and integral solderless printed conductors between adjacent wafers. When the wafers are series connected, apertures are provided in the sheet through which the printing material extends to series connect adjacent wafers. The wafers may be secured within the sheet by securing same within apertures therein or elongated crystals may be disposed in a mold and electrically insulating material may be cast therearound to form a block which may then be sliced into modules.
