1. A solar cell apparatus comprising:
a plurality of back electrodes spaced apart from each other on a substrate; a light absorption layer including division gaps to divide cells into a plurality of unit cells on the substrate formed with the back electrodes; top electrodes spaced apart from each other by the entire division gaps on the light absorption layer; and an insulator comprising insulating material on the back electrodes, wherein the light absorption layer further includes a plurality of contact gaps, wherein the top electrodes are filled in the contact gaps and electrically connected to the back electrodes, wherein an upper surface of the insulator is lower than an upper surface of the light absorption layer, wherein the upper surface of the insulator is the surface of the insulator farthest away from the substrate, and the upper surface of the light absorption layer is the surface of the light absorption layer farthest away from the substrate, wherein each unit cell includes a contact gap of the plurality of contact gaps, and wherein, within each unit cell, a portion of the light absorption layer is disposed between the contact gap and an adjacent division gap, in a first direction parallel to a top surface of the substrate. |
