Surface and Interfaces matter!
We use scanning probe and photo-electron spectroscopy methods to study the fundamental properties of surface and interfaces in solar cell and 2D materials.
Surface and Interfaces of Cu(In,Ga)Se2 & halide pervoskites
Chalcopyrite & halide perovskites are materials that are used to fabricate high efficiency thin film solar cells. We use scanning probe and photo-electron spectroscopy to understand the impact of alkali metals in CIGSe. We synthesize Pb-free perovskites and study degradation pathways to make these materials stable. We study and functionalize 2D materials like MoS2 & 2D halide perovskites.
