Although commonly known solar cells convert light directly into electrical energy, there are another solar-powered energy conversion system called photoelectrochemical (PEC) cells that have attracted attention in recent times due to direct energy production in combination with electrical energy.
PEC cells use solar energy to split water into simple and safe compounds to divide into hydrogen and oxygen, hydrogen is a high-energy fuel that can be stored and used as needed. These cells are therefore considered sacred grills for the carbon-free hydrogen economy.
This is a field of research for a team from the Department of Chemistry at IIT Guwahati led by Mohammad Qureshi. The team reported its latest findings in the American Chemical Society’s prestigious peer-reviewed journal, the Journal of Physical Chemistry Letters. The co-authors of the paper are Professor Mohammad Qureshi and Suhaib Alam. The team has developed a non-noble metal catalyst that is just as good as the expensive metal in water separation in PEC cells.
