Research formulation scientist at Hindustan Platinum developing PERC and TOPCon silver paste and reclaim technology.

Switzerland

Message

At Hindustan Platinum Pvt. Ltd., I develop and formulate PERC- and TOPCon-compatible silver paste and optimize production processes. I also work on silver powder synthesis and silver reclaim technology from rejected wafers.

At École polytechnique fédérale de Lausanne, PV lab, I carried out mechanical stability and reliability studies of perovskite/silicon tandem solar cells. I studied adhesion in the thin-film solar-cell stack and linked mechanical rupture with structural deformation.

At IIT Bombay, I researched perovskite solar-cell performance through compositional and process engineering, including molecular doping and interface analysis. Earlier, I developed silver nanostructure synthesis protocols and worked on silver paste for silicon solar cells.
