The National Renewable Energy Laboratory (NREL) in the United States has recently verified that Alta Devices' new "double-junction" thin-film solar cell technology has achieved a remarkable conversion efficiency of 30.8%. This breakthrough marks a significant advancement in the field of photovoltaic technology and highlights the company's ongoing commitment to innovation. Chris Norris, President and CEO of Alta Devices, shared his enthusiasm about the achievement: “Since 2010, we have consistently pushed the boundaries of solar efficiency. This new double-junction cell with a record-breaking 30.8% efficiency is a testament to our world-class team and our relentless pursuit of excellence. We are confident that this development brings us one step closer to our long-term goal of reaching 38% efficiency.†The company’s latest technology integrates indium gallium phosphide (InGaP) as the top absorber layer in the second junction, built on top of a single-junction cell base. This design allows for more efficient utilization of sunlight by capturing a broader range of the solar spectrum. Indium gallium phosphide is known for its superior performance in converting high-energy photons compared to traditional single-junction gallium arsenide (GaAs) cells. This makes it an ideal material for next-generation solar technologies. While Alta Devices is currently shipping its single-junction GaAs products, the introduction of this double-junction system represents a major leap forward in both efficiency and performance. With continued research and development, Alta Devices aims to further enhance its solar solutions, making renewable energy more accessible and cost-effective for a wide range of applications. This latest achievement not only reinforces their leadership in the industry but also signals a promising future for high-efficiency solar technology.
