ARPA-E awards $175M to 68 novel clean energy OPEN 2021 projects

Green Car Congress

The new superjunction structure will surpass the theoretical trade-off between on- resistance and breakdown voltage observed in conventional unipolar GaN, leading to more efficient and cheaper power converters. This would eliminate the ionomer, which conducts ions, but also poisons catalyst sites and obstructs oxygen transport.
