  "account": "Advanced Renewable Tandem-Photovoltaics India Private Limited, or ART-PV India, is a Mumbai-based company founded by Professor Dinesh Kabra from IIT Bombay. The company aims to push past the silicon solar cell limit by stacking two solar cells, a tandem approach.\n\nThe technology behind ART-PV India's solution is a two-terminal monolithic silicon and CdTe-perovskite tandem cell. This means the layers are grown as a single device and the cell features the same two electrical connections as an ordinary panel. The tandem cell achieves a reported 29.8% conversion efficiency, surpassing the ceiling of 29% for single-junction silicon cells.\n\nSupport from the government and industry partners has bolstered ART-PV India's efforts. The company has received about $10 million from the Ministry of New and Renewable Energy for a pilot facility. Both First Solar and Waaree, India's largest crystalline silicon manufacturer, are partners. They hold preferential licensing rights, which will help develop and commercialize the technology.\n\nThe company plans to build a 5,000 sq ft ISO 7 cleanroom at IIT Bombay for the production of the tandem cells. This modular architecture permits compatibility with both major panel technologies, crystalline silicon and cadmium telluride thin film. The top layer of the tandem cell can be applied onto either of these materials, catering to the industry's needs.",
  "summary": "The IIT Bombay spinout has built a tandem cell combining perovskite with silicon and CdTe, and is setting up a pilot manufacturing line on campus with government funding.",
