Solar photovoltaics (PV), coupled with large-scale energy storage, will be central to achieving global net-zero targets. With global PV deployment projected to grow from ~1 TW (2022) to ~75 TW by 2050, next-generation technologies must deliver higher efficiency, lower cost, and reduced carbon footprint to meet climate goals aligned with the Paris Agreement.
Metal-halide perovskites offer tunable bandgaps and exceptional optoelectronic properties, enabling tandem architectures with theoretical efficiencies beyond 45%. Industrial R&D has already demonstrated 34.9% efficiency at 1 cm² and >30% on commercial wafer sizes. At NCPRE, IIT Bombay, we have achieved 30.2% efficiency at lab scale and are actively scaling toward commercial wafer formats through our venture, ART-PV India. This talk will discuss the scientific foundations, device engineering strategies, and scalable pathways enabling high-efficiency tandem photovoltaics for energy transition.
