Researchers from the Indian Institute of Technology (in Delhi, India) have shown that layers of graphene deposited on silicon have excellent anti reflection properties. The researchers demonstrated (using theoretical calculations and experiments) that CVD-deposited graphene is much better as a UV anti-reflectance layer compared to the commonly used Si3N4 layer used in current solar-cells.
Earlier this month we reported on a new research (from Peking University) showing that Titanium Dioxide can be used as a anti-reflective layer in graphene-silicon solar cells to make them more efficient.
