January 6, 2025

China’s Trina Solar (688599.SS) has achieved a groundbreaking milestone in solar technology, setting a new world record for conversion efficiency in its n-type fully passivated heterojunction (HJT) modules. The company announced the achievement on Monday, following certification by Germany’s Fraunhofer CalLab, a leading solar research institute.

A Leap Forward in Efficiency

In laboratory tests, Trina’s HJT modules demonstrated an impressive 25.44% efficiency. This refers to the percentage of sunlight converted into usable electricity, a key metric in solar technology. By enhancing cell efficiency, solar installations can be downsized while costs are reduced, offering a significant advantage in the renewable energy market.

The technology behind the achievement, known as passivation, involves covering surface defects on solar cells to improve their performance. According to Professor Martin Green from the University of New South Wales, Sydney—whose lab previously held the efficiency record for decades—the result underscores the promise of HJT as a next-generation solar technology.

“In the long run, it’s all about efficiency,” Green said. “Even if some technologies are initially more expensive, costs tend to drop quickly as the industry adapts and scales up.”

Trina Solar’s Vision

Trina Solar’s Chairman and CEO, Gao Jifan, emphasised the company’s commitment to advancing passivated solar technology through ongoing research and development. “This achievement strengthens our leadership in solar technology, and we will continue to push the boundaries of innovation,” he stated.

The Future of HJT Technology

While HJT technology currently represents a small share of the market—estimated at 7% of high-efficiency solar cell capacity in 2024, rising to 9% by 2026—it holds significant potential. However, it faces stiff competition from TopCON (Tunnel Oxide Passivated Contact) technology, which is projected to dominate the market over the next five years.

This milestone not only represents a breakthrough for HJT technology but also sets a new benchmark for the photoelectric conversion efficiency of single-crystalline silicon solar cell modules, Trina noted in its statement.

As the race for efficiency continues, innovations like these are expected to play a crucial role in shaping the future of renewable energy.

Only 1% Of Cyprus Farms Use Precision Farming Technologies

Cyprus remains one of the European Union’s least digitised agricultural economies, with just 1% of farms using precision farming technologies in 2023, according to Eurostat.

The findings come as the EU continues to encourage the adoption of digital tools aimed at improving agricultural productivity, efficiency and sustainability.

Internet Access Expands, But Digital Uptake Lags

Internet access has improved across the bloc, although adoption remains uneven. Eurostat found that 43% of EU farms had internet access in 2023, with northern and central European countries leading the way.

Denmark, Germany, Slovakia, Latvia, the Czech Republic and Austria all reported internet access rates above 90%.

Greater connectivity, however, has not translated into widespread digital adoption. Farm management information systems, which help farmers manage day-to-day operations, were used by only about 11% of EU farms. France was a notable exception, with around 60% of farms using the technology.

Precision Farming Concentrated In Larger Operations

Robotics adoption also remained relatively limited, with only about 7% of EU farms using robotic technologies. Overall, around 18% of farms with utilised agricultural area employed at least one precision farming technology or practice in 2023.

These included robotics for plant protection, band spraying, variable-rate application, precision crop monitoring and soil analysis. Despite representing fewer than one in five farms, these holdings accounted for around 44% of the EU’s utilised agricultural area.

The figures suggest that precision farming remains concentrated among larger agricultural businesses, where investment in digital technologies is typically easier to support.

Cyprus Lags Behind EU Leaders

Luxembourg, Finland and Estonia recorded the highest shares of utilised agricultural area managed by farms using precision farming technologies, each exceeding 75%.

At the other end of the ranking, Cyprus recorded just 1%, while Greece and Romania reported between 10% and 15%. The results indicate that Cyprus remains at an early stage of digital adoption in agriculture, even as precision farming becomes more widespread across parts of the European Union.
