Decarbonization and the transition to sustainable energy are crucial global priorities, and two key technologies at the forefront of this transformation are photovoltaic solar energy and green hydrogen production. Photovoltaic (PV) solar energy has emerged as a leading renewable technology. Advanced materials such as copper-zinc-tin-sulfide and metal oxide-based materials play a critical role for the sustainable energy harvesting. The integration of nanomaterials has pushed the boundaries of solar energy conversion, enabling higher light-to-electricity efficiencies and the development of flexible, lightweight, and cost-effective solar panels.

Alongside photovoltaics, the production of green hydrogen through water electrolysis powered by renewable energy sources is a promising pathway for decarbonization. Nanomaterial-based catalysts, such as highly active and durable nanoparticles, are revolutionizing the efficiency and cost of the water-splitting process, enabling the direct conversion of solar energy into hydrogen fuel. The widespread adoption of photovoltaic and green hydrogen technologies, supported by continued advancements in materials science and engineering, will be instrumental in driving the global transition towards a decarbonized and sustainable energy future.
