This image depicts a hydrogen fuel cell ecosystem, showing the complete cycle from renewable energy production to zero-emission transportation. Solar panels generate electricity to power electrolysis, splitting water (H2O) into hydrogen (H2) and oxygen (O2). The produced hydrogen fuels a clean vehicle at a refuelling station, illustrating a sustainable hydrogen energy technology. More information can be found in the Review by S.

This study demonstrates the potential of hybrid perovskite solar cells for photocatalytic water splitting and sustainable hydrogen production. By combining bandgap engineering and heterojunction design, enhanced efficiency and clean energy generation are achieved, advancing next-generation solar-driven hydrogen technologies.
 
Perovskite solar cells (PSCs) have recently emerged as a viable technology for photovoltaic applications, offering high efficiency and cost-effective manufacturing. Beyond generating electricity, PSCs can also facilitate hydrogen production through water splitting. This article provides a comprehensive review of current research on PSCs for hydrogen production, highlighting their potential as a transformative technology in this field. The challenges and opportunities associated with using PSCs for hydrogen production are discussed, including their stability and efficiency under various operating conditions. The impact of device design, system integration, and materials engineering on PSC performance for hydrogen production is also examined. Furthermore, an overview of hydrogen demand is provided and how PSCs can be integrated with other renewable energy sources to contribute to a sustainable energy future through green hydrogen production is explored. The analysis suggests that hydrogen production using PSCs has the potential to become a groundbreaking technology, significantly impacting the energy sector and the transition to low-carbon energy.
