A New Method Improves Kesterite Solar Cells, Making Them More Efficient

Researchers at the University of New South Wales have set a new efficiency record for kesterite-based solar cells, achieving 11.4 percent power conversion efficiency using hydrogen annealing. This method enhances carrier collection by redistributing sodium and oxygen, reducing defects, and improving charge transport. The findings, published in Nature Energy, suggest t...
