Solar Power Breakthrough: Kesterite Hits 13.2% Efficiency, Surpassing Silicon And Perovskite

Kesterite solar cells just hit a record 13.2% efficiency, giving silicon and perovskite a run for their money. Developed by UNSW researchers using hydrogen annealing, this low-cost, eco-friendly material could redefine the future of solar power. Ideal for off-grid use, rural applications, and tandem panels, kesterite brings sustainability, affordability, and solid performance to the table. Learn why this solar underdog is suddenly in the spotlight.
