The National Renewable Energy Laboratory (NREL) in the United States has recently validated a major breakthrough in solar technology, confirming that Alta Devices' new "double-junction" thin-film solar cell has achieved a remarkable conversion efficiency of 30.8%. This represents a significant leap forward in the field of photovoltaics and highlights the company's ongoing innovation in renewable energy solutions. Chris Norris, President and CEO of Alta Devices, commented on the achievement: "Since 2010, we've consistently pushed the boundaries of solar efficiency. This new double-junction design, with its 30.8% efficiency, is a testament to our world-class team and the strength of our technology. It brings us one step closer to our long-term goal of reaching 38% efficiency, which we believe will redefine the future of solar power." The company's latest technology features a dual-layer structure, where indium gallium phosphide (InGaP) serves as the top absorber layer, combined with a single-junction base. This configuration allows the device to capture a broader spectrum of sunlight, improving overall performance compared to traditional single-junction cells. Indium gallium phosphide is known for its superior ability to convert high-energy photons into electricity, outperforming conventional gallium arsenide (GaAs) cells in certain conditions. While GaAs remains a popular choice for high-efficiency solar applications, Alta Devices is now leveraging the advantages of InGaP to enhance performance further. Currently, the company is already shipping its single-junction GaAs technology to customers, but the introduction of this double-junction system marks a key milestone in their roadmap. As the demand for more efficient and cost-effective solar solutions continues to grow, Alta Devices is well-positioned to lead the next phase of innovation in the industry.
