Patent ID: 8835754

Claim:
A method of manufacturing a see-through thin film solar cell, comprising the steps of: S 1 : Forming a photoelectric conversion film on a surface of a first substrate; S 2 : Placing a patterned photo mask above the photoelectric conversion film, the photo mask including a high mask section and a low mask section that are formed at different thicknesses; S 3 : Ablating the photoelectric conversion film via a laser beam scanning and passing through the patterned photo mask to form at least one hollow-out zone on the photoelectric conversion film, the hollow-out zone including a high transparent section corresponding to the low mask section and a low transparent section corresponding to the high mask section wherein the thickness controls the intensity of the laser beam passing through the patterned photo mask; S 4 : Preparing a second substrate and a packaging adhesive film disposed between the first substrate and the second substrate; and S 5 : Bonding the first substrate and the second substrate through the packaging adhesive film, wherein the first substrate is bonded to the second substrate with the surface thereof including the photoelectric conversion film through the packaging adhesive film to form a solar cell.
