Taking a significant step in increasing solar energy production efficiency, two major Chinese companies have set new world records in solar cell technology. These achievements will accelerate the global transition to clean energy sources and once again confirm China's leadership in this field.
In April 2026, Trina Solar achieved 28% conversion efficiency with its back-contact solar cell. This figure marks a first for this type of large-format silicon cell, signifying a substantial improvement in solar panel design and performance.
During the same period, LONGi also surpassed its previous record, achieving 28.13% efficiency with its HIBC (hybrid interdigitated back contact) cell. This result is one of the highest achieved in converting sunlight into electricity, opening new possibilities in energy production.
These innovative technologies are currently being prepared for mass production. This means that in the near future, a new generation of solar panels will be significantly more efficient in converting sunlight into electricity, providing more affordable and sustainable energy sources for consumers and industry.
These achievements play a crucial role in shaping the future of clean energy and demonstrate the rapid pace of progress in the renewable energy sector worldwide. The information is based on a report from The Energy Mix, dated May 12, 2026.
