SnO2 Layers for Scalable Fullerene-Free Perovskite Solar Cells

Review noteA 2022 University of Louisville spin-out making tin-oxide and nickel-oxide nanoparticle inks for perovskite solar cells; it announced a $6M seed in July 2026 with trade-press coverage, so it is known in solar circles though not on Hacker News. The two capital signals are the same NSF grant counted twice. Source ↗
