In this work we use 3D numerical simulations to design optimized point contacts in back-side passivated CIGS cells. We performed a detailed analysis of point contact size for different CIGS thickness, contact specific resistance, as well as chemical and field-effect passivation properties. The role of CIGS energy gap back-grading in improving the performance of cells with different absorber thickness has also been addressed.
