Power Grid

Heterojunction (HJT) solar panels, powered by innovative technology, have once again garnered attention after achieving a new world record for solar power generation efficiency at an impressive 25.44%. This breakthrough was accomplished by Trina Solar, a Chinese company that integrates traditional silicon solar panels with thin-film solar cells. This combination significantly improves both the efficiency and performance of the panels, particularly under low light conditions, surpassing the capabilities of conventional solar panels.

The HJT panels also offer enhanced durability and a longer lifespan, making them an appealing choice for both residential and commercial solar energy projects. Trina Solar’s achievement marks a significant milestone, as it sets a new benchmark in the photovoltaic industry.

This new efficiency record is Trina’s 30th record-breaking achievement, underscoring the company's ongoing leadership in solar technology. The 25.44% efficiency surpasses the previous record of 25.40%, which was set by Chinese competitor Longi's back-end solar modules.

Recent laboratory tests, conducted by the German Fraunhofer CalLab, have confirmed the breakthrough. The tests demonstrated that the large surface area of HJT-equipped solar cells enabled them to reach an efficiency of 25.44%. One of the key features of this technology is its “damping” mechanism, which covers defects on the surface of the solar cells.

This mechanism plays a crucial role in improving the overall cell efficiency, allowing a higher percentage of sunlight to be converted into usable electricity. Increased cell efficiency could also lead to smaller and more cost-effective solar installations.

Trina Solar continues to push the envelope in solar research and development, with a focus on enhancing the damping mechanism to maintain its edge in the competitive solar energy market. Although highly efficient damping solar cells still account for a small portion of the market, their share is expected to grow in the coming years.

Meanwhile, TopCon cells, which are made from nitrate silicon, are predicted to dominate the solar cell market over the next five years. Trina’s recent records further emphasize the rapid progress of HJT technology and its potential to shape the future of solar energy generation.
