Trina Solar has achieved a groundbreaking milestone in solar technology by setting a new world record for n-type solar cell efficiency at 27.08%. This remarkable achievement was independently verified by the Institute for Solar Energy Research in Hamelin (ISFH), marking the first time a crystalline silicon solar cell with front and back contact structure has surpassed 27% efficiency. The record-setting cell utilizes innovative technologies, including a 210mm×105mm half-cut, phosphorus-doped n-type silicon wafer produced through the Czochralski process, demonstrating significant advancements in photovoltaic research.

The company's breakthrough stems from multiple cutting-edge technological developments. Trina Solar enhanced the cell's performance through advanced techniques such as full rear-side passivation heterojunction methods, multi-frequency RF doping optimization for microcrystalline systems, and ultra-fine line printing technologies. These innovations significantly improve both optical and electrical efficiency, positioning Trina Solar at the forefront of solar energy research. The solar cell integrates optimized thin-film passivating contact, a progressive variable-frequency-RF nanocrystalline p-type emitter, advanced light trapping, and very fine line printing technologies to achieve its record-breaking performance.

This achievement represents Trina Solar's 29th world record for solar cell efficiency, underscoring the company's commitment to technological innovation. Gao Jifan, Chairman and CEO of Trina Solar, emphasized the company's dedication to advancing passivated contact cells and modules. The breakthrough is particularly significant as it crosses the critical 27% efficiency threshold, demonstrating substantial improvements in solar technology. N-type solar cells are known for their superior efficiency compared to traditional p-type cells, promising increased energy output and potentially more cost-effective solar solutions.

The record has broader implications for renewable energy development. By pushing the boundaries of solar cell efficiency, Trina Solar is contributing to the global transition to clean, sustainable energy. The improved efficiency translates to reduced cost per watt of solar energy, potentially making solar power more affordable and accessible worldwide. This milestone builds upon the company's previous achievements, including earlier records of 25.9% and 26.58% efficiency for n-type monocrystalline tunnel oxide passivated contact (TOPCon) cells. The breakthrough reinforces Trina Solar's leadership in both high- and low-temperature passivated contact technologies, signaling a promising future for solar energy innovation.
