Patent ID: 8592246

Claim:
A method of manufacturing a solar cell module, comprising: forming lower electrodes, including a first lower electrode and a second lower electrode, on a substrate; forming a light absorption layer on the lower electrodes and the substrate; patterning the light absorption layer to form only a single trench exposing the lower electrodes; and forming window electrodes, including a first window electrode and a second window electrode, from a conductive film, the first window electrode extending from a top surface of the light absorption layer to a bottom of the single trench along one-sidewall of the single trench, the first window electrode contacting in the single trench one of the first lower electrode and the second lower electrode, and the second window electrode being separate from the first window electrode and being disposed on another-sidewall of the single trench, wherein the single trench is disposed between the first window electrode and the second window electrode.
