Qcells Sets New Benchmark in Tandem Solar Cell Efficiency

Qcells Achieves Unprecedented Tandem Solar Cell Efficiency

Qcells, a renowned provider of energy solutions, has made headlines with its remarkable achievement in the solar energy sector, reaching a world record efficiency of 28.6% for tandem solar cells. This milestone was recorded on a full-area M10-sized solar cell that is ready for mass production, showcasing not just an impressive technological innovation but also the company’s commitment to advancing solar technology. With the enormous global demand for efficient renewable energy solutions, reaching this level of efficiency highlights Qcells’ pivotal role in pushing the boundaries of solar technology.

Breakthrough Technology in Solar Power

The groundbreaking tandem cell technology developed at Qcells promises to transform the commercialization process for solar solutions. According to Danielle Merfeld, Global CTO at Qcells, this advancement represents a crucial leap forward in photovoltaic performance. The company plans to continue investing significantly in research and development, understanding that every kilowatt saved is vital for fostering a sustainable future.

Certified Efficiency Shines

The impressive 28.6% efficiency record achieved by Qcells has been independently verified by the CalLab at the Fraunhofer Institute for Solar Energy Systems (ISE). This achievement progresses the industry towards deploying solar technology that is not only more effective but also more economically feasible. The tandem solar cell combines a perovskite technology for the top layer and Q.ANTUM technology in the silicon-based bottom layer. This integration enables the solar cell to capture a broader spectrum of sunlight, optimizing energy output.

Enhancing Solar Energy Production

The innovative stacking of perovskite and silicon solar cells enhances light absorption, maximizing efficiency by allowing high-energy light to be captured by the top cell while low-energy light passes through to be absorbed by the bottom cell. This design not only increases the power output per area but also reduces the number of modules needed to produce the same energy level. These enhancements could significantly decrease the costs associated with solar energy production while also reducing the land required for solar projects.

A Vision for the Future

Since embarking on a mission in 2016, Qcells have worked tirelessly to develop a commercially viable tandem solar cell. The company accelerated its efforts in 2019 with the establishment of a dedicated R&D center in Pangyo, Korea, along with operations in Bitterfeld-Wolfen, Germany. These facilities have seen considerable development in small-area tandem cells, which ultimately paved the way for the new efficiency record.

Support from Government Initiatives

Qcells’ advancements have benefited from numerous government collaborations. The development process for this groundbreaking tandem cell was backed not only by the German government but also by the state of Saxony-Anhalt and multiple European funding initiatives. This collaborative effort demonstrates the importance of partnerships in driving innovation within the renewable energy sector.

Global R&D Teams Unite for Innovation

Powerful synergies are forming as Qcells collaborates with its global R&D teams. Danielle Merfeld emphasized the significance of collaboration, stating that the collective expertise has been vital in sparking innovations aimed at achieving environmental sustainability goals.

Qcells: A Leader in Clean Energy

As one of the leading clean energy firms, Qcells distinguishes itself with its high-quality solar cells and modules. The company is recognized not only for its technological prowess but also for its portfolio of intelligent storage systems and substantial pipeline of renewable energy projects across the globe. With headquarters in Seoul, South Korea, Qcells operates manufacturing facilities in the U.S., Malaysia, and South Korea, continually striving to deliver completely clean energy solutions.
