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

Abstract

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.
