LONGi Sets a New World Record of 27.09% for the Efficiency of Silicon Heterojunction Back-Contact (HBC) Solar Cells

LONGi, a Chinese solar panel manufacturer, has set a new world record for the efficiency of silicon heterojunction back-contact (HBC) solar cells. The company achieved 27.09% efficiency using an all-laser patterning process to overcome the high patterning cost of back-contact cells.

The design allows the entire front surface to capture sunlight without being partially shaded by metal contacts, making the cell more efficient. This breakthrough in solar cell technology will lead to higher efficiency with reduced manufacturing costs. LONGi's achievement is a significant step towards achieving the goal of making solar energy more affordable and accessible to everyone.
