Thin Film Solar Cells
Rear surface passivation for CIGS solar cells have shown the potential to increase the efficiency. Al2O3 and SiO2 have been used as the passivation materials. Nano-sized point contacts on Al2O3 layer [1] and line contacts on SiO2 layer [2] provide the electrical connection of CIGS absorber to the rear electrode Molybdenum. The point contacts on the Al2O3 layer are created by e-beam lithography and the line contacts on the SiO2 layer are created using photolithography. Also, the implementation of the passivation layers does not change the morphology of the CIGS layers.
