Posted: Tue Feb 11, 2025 4:22 am
Chinese solar module manufacturer Longi has introduced a new heterojunction cell (HBC) solar cell that has achieved an impressive efficiency of 27.30%.
Advanced technologies
The use of advanced technologies such as edge wafer passivation and optimization of the front anti-reflective coating allowed Longi to achieve record efficiency. The company's researchers emphasize the importance of controlling the recombination of charge carriers, which is critical to achieving high solar cell efficiency.
Laser modeling and mass production
Longi has adopted laser ablation as a mass production chinese thailand data technology, which has helped achieve a certified efficiency of 27.09% for HBC solar cells. Amorphous silicon is used as a passivation contact layer, which improves overall performance.
Study of recombination losses
The company's researchers conducted extensive experimental and theoretical testing to study recombination, resistive, and current density losses. They found that the main recombination losses occur through the hole-selective contact region and proposed solutions to optimize the structural design of the batteries.
Effect of plate edge on efficiency
The study found that the wafer edge becomes the main source of current density loss due to carrier recombination. This finding highlights the need for further design optimization to improve efficiency.
Development Prospects
Longi continues to improve its technologies, trying to push the boundaries of solar energy achievements. In particular, the company plans to continue researching and implementing new solutions that contribute to the development of efficient and sustainable solar panels.
The introduction of innovative technologies and research opens new horizons for solar energy, making it more efficient and accessible to consumers.
