Chinese company Trina Solar set a fresh planet evidence in terms of solar module conversion efficiency.
In laboratory tests certified by Fraunhofer CalLab, a German solar energy investigation unit, full passivated hetero-connection modules (HJT) Trina showed a performance of 25.44 percent.
Passiveness is simply a method utilized to reduce electron recombination by passivating or reducing defects on the surface of a solar cell. This layer acts as a barrier, preventing recombinant electrons from being raised with holes and alternatively directing them where they can contribute to the production of electricity
By expanding the efficiency of cells you can reduce the size of solar installations and thus reduce their costs.
Professor Martin Green of the University of fresh South Wales in Sydney, whose laboratory maintained for decades a evidence of solar cell efficiency, in consequence to reports from China, said that the consequence obtained by Trina Solar shows the possible of HJT technology, 1 of the fewer that conflict to become the dominant next generation technology in the sector.
The CEO and CEO of Trina Solar, Gao Jifan, said the company would intensify its R & D work on passive solar technology to keep its technological leader position.
HJT is presently a small-scale technology. According to InfoLink consulting company, in 2024 it accounted for 7 percent in terms of the power of high-performance solar cells, this year it will be 8 percent, and in 2026 about 9 percent in this niche. TopCON cells, i.e. tunnel-activated passive cells, are expected to represent most of the marketplace over the next 5 years.
TOPCon, the Tunnel Oxide Passivated Contact, is another solution to increase the efficiency of cells in photovoltaic installations. In this case, the cell surface is covered with additional silicon layers, which supply better contact with electrodes and minimize energy losses caused by interior resistance. This technology gives cells more efficient and with lower degradation over time. However, it is more costly than HJT due to the request for much more silver.
Hence the efforts of companies like Trina Solar to get akin parameters of cells, but cheaper in mass production. Mass through large “M”.
The results obtained by Trina Solar represent a evidence for HJT technology, but at the same time are an crucial step in the efficiency of the conversion of photoelectric solar cell modules from monocrystalline silicon.
