Hands-On Training in the Design and Fabrication of N-Type Solar Cells

A new laboratory design has been developed that involves both theoretical modeling and practical implementation of n-type wafer based solar cells. PC1D and EDNA, two open source software packages, are utilized by the students to model and design a diffusion based process. The optimal design is chosen for lap implementation and characterization follows. Industrial quality QE gives student´s experience with AR coating design and passivation concepts. Future lab development will include chemical processing for optical light trapping, grid contact design, and creation of front/back contacts via screen printing.
