Semi-transparent Perovskite Solar Cell
- IIT Bombay researchers have created a semi-transparent perovskite solar cell (PSC) that offers 25–30% higher efficiency than traditional solar cells, potentially reducing costs by half. This PSC features a 4-terminal tandem design, layering a perovskite top cell over a silicon-based bottom cell.
- The top cell uses an indigenously developed halide perovskite semiconductor, enhancing light absorption and energy conversion.
- Key advantages include local production, long lifespan, and independence from geopolitically sensitive materials, unlike some silicon components controlled by China.
- This innovation promises a more efficient and cost-effective solar energy solution.
