Discover how a thin film of common metals could power the future.

In this visually engaging and informative PDF, explore how Chinese researchers have achieved a world record in solar-to-hydrogen conversion using a low-cost, non-toxic material called CZTS (copper, zinc, tin, sulfur). This innovation enables clean hydrogen production from untreated seawater using only sunlight—no rare materials, no external power, and no emissions.

This breakthrough could revolutionize energy access for remote coastal communities, decarbonize heavy industries, and accelerate the global green hydrogen economy. With its potential to lower costs and reduce environmental impact, this technology is a major step toward a sustainable, decentralized energy future.
