Qcells, a global leader in solar energy solutions, has achieved a groundbreaking milestone: a world-record 28.6% efficiency for its tandem solar cell. This achievement, independently verified by the Fraunhofer Institute for Solar Energy Systems (ISE), marks a significant leap forward in photovoltaic technology. The record-breaking efficiency was achieved using a full-area M10-sized cell, crucial for mass production and commercial viability. This isn’t just a lab experiment; Qcells’ success utilizes a scalable approach, focusing on industrial processes that can be readily implemented on a larger scale. The tandem cell design cleverly combines perovskite and Q.ANTUM silicon technologies. The perovskite top cell efficiently captures high-energy light, while the silicon bottom cell captures lower-energy light, maximizing overall energy conversion. This innovative approach leads to higher power output per unit area, reducing the number of modules required for a given solar system power output, thus contributing to lower costs and a smaller land footprint. This breakthrough underscores Qcells’ commitment to advancing sustainable energy solutions. The company has been investing heavily in research and development since 2016, focusing on large-area tandem development since 2023. Their dedication has been supported by substantial funding from the German government, the state of Saxony-Anhalt, the EU commission (including the PEPPERONI project), and the Korean government. The development of this technology has been a global collaborative effort, highlighting the importance of international partnerships in driving technological advancements in renewable energy. Experts see this as a game-changer, bringing the commercialization of highly efficient, affordable solar energy closer to reality. The improved efficiency translates to lower costs and a reduced environmental impact, making solar energy even more accessible and appealing. This new record in tandem cell efficiency is based on Qcells’ in-house developed perovskite technology for the top cell and cost-efficient Q.ANTUM silicon technology for the bottom cell. The cell produced is typical of those from their R&D pilot line, and the fabrication process is designed for mass production, paving the way for commercialization. This technology holds the promise of significantly decreasing the cost of solar power while simultaneously reducing the environmental footprint required for solar energy generation. The focus on scalable manufacturing processes ensures that this achievement translates directly into real-world impact, accelerating the global transition to renewable energy sources. Qcells’ dedication to innovation and sustainable practices positions them as a key player in shaping the future of solar energy, aligning perfectly with global efforts to combat climate change and build a more sustainable future. The company continues to push boundaries, exploring cutting-edge technologies to enhance solar energy efficiency and affordability, making sustainable energy more accessible worldwide.
