Abstract: A thin film solar cell includes a first substrate, a first electrode on the first substrate, and divided by a first dividing groove, a light absorbing layer disposed on the first electrode, and divided by a second dividing groove parallel with the first dividing groove, a second electrode disposed on the light absorbing layer, divided by a third dividing groove that parallel with the first and second dividing grooves, a second substrate disposed on the second electrode, facing the first substrate, and a metal foil attached to the first substrate and the second substrate to encapsulate a gap between the first substrate and the second substrate, a first end portion of the metal foil being attached to a first surface of the first substrate using a metal material, and a second end portion of the metal foil being attached to the second substrate.

Abstract: A solar cell module includes a substrate, a lower electrode on the substrate, a light absorption layer on the lower electrode, an upper electrode on the light absorption layer, and a protective layer on the upper electrode, the protective layer extending along sidewalls of the light absorption layer to the lower electrode, the protective layer including a moisture absorbing material.

Abstract: A thin film solar cell module and a method of manufacturing a thin film solar cell module. A thin film solar cell module includes: a thin film solar cell including a first substrate, and a first electrode layer on the first substrate; a second substrate covering the thin film solar cell; and a sealing tape between the thin film solar cell and the second substrate, the sealing tape including a first adhesive layer having a conductivity and being attached to an edge portion of the first electrode layer; a metal layer on the first adhesive layer; and a second adhesive layer on the metal layer and attached to the second substrate.
