Longi Achieves 27% Efficiency in Solar Technology

In a recent paper called “Silicon Heterojunction Back Contact Solar Cells by Laser Designing,” LONGi announced that their crystalline silicon solar cells have accomplished over Longi Achieves 27% Efficiency to begin with time. This is a vital step forward in solar technology. It shows that back-contact solar cells can be both very efficient and cost-effective, setting a new standard for the industry.

Innovations in Heterojunction Solar Cells

LONGi’s Central R&D Institute has made this breakthrough by doing a lot of research on silicon wafers and passivation technology. They created a strong heterojunction contact and improved the way heterojunctions are made. Their new method uses a fully laser-patterned design and a way to apply metal without using indium or silver, which makes future back-contact solar cells more efficient and cheaper to produce.

Leadership in Monocrystalline Silicon Technology

This new achievement follows Longi earlier announcement in May, when their HBC (heterojunction back-contact) solar cells reached an efficiency of 27.30%, setting a world record for monocrystalline silicon cells. This beat the previous record of 27.09% from December 2023, showing that LONGi is a leader in making highly efficient solar technology.

Solar Cell Efficiency Over Time

Over the years, crystalline silicon solar cells have improved in three main ways: Al-BSF cells (less than 20% efficiency), PERC cells (up to 25% efficiency), and TOP Con cells (over 25%). Now, back-contact (BC) technology is set to lead the next phase of production, with efficiencies of over 26%. Longi research shows that by combining heterojunction technology with a BC design, they aim to achieve efficiencies greater than 27%.

Pioneering Research from Longi R&D Team

LONGi is dedicated to innovation, as shown by this being the third article published in Nature by their Central R&D Institute since 2024. These articles followed previous reports about world records in flexible silicon heterojunction cells and perovskite/crystalline silicon tandem cells. These successes highlight Longi leadership in advancing solar technology. As a global leader, LONGi actively improves solar energy and drives new technological advances. And supports a more efficient and sustainable future for solar power through ongoing innovation and teamwork in the industry.
