Scientists at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have made a groundbreaking advancement in green hydrogen production. They have introduced a device that can generate green hydrogen by splitting water molecules using only solar energy and common materials, marking a significant shift away from fossil fuels and expensive resources. Led by Dr. Ashutosh K. Singh, the research team developed a state-of-the-art silicon-based photoanode with a unique n-i-p heterojunction architecture, enabling improved charge separation and transport efficiency. The device exhibited exceptional stability and efficiency, operating continuously for over 10 hours with minimal performance degradation. This achievement, published in the Journal of Materials Chemistry A, showcases the potential for large-scale solar-to-hydrogen energy systems that are highly efficient, durable, and cost-effective. Dr. Singh emphasized the scalability and affordability of this technology, envisioning its application in various sectors, from residential to industrial, thereby advancing sustainable energy solutions.
