LONGi Green Energy Technology Co, a global leader in solar technology, has once again made headlines by setting a new world record for the efficiency of crystalline silicon heterojunction back-contact (HBC) solar cells. This groundbreaking achievement, with an efficiency rate of 27.09%, has been certified by the Institute for Solar Energy Research Hamelin (ISFH) in Germany. This efficiency milestone surpasses the previous record of 26.81% set in November 2022 and stands as a testament to LONGi's continuous innovation in the solar energy sector.
The record-setting 27.09% efficiency HBC cell was developed independently by LONGi using an innovative all-laser patterning process. This process signifies a major technological advancement, particularly in addressing the challenge of high patterning costs associated with back-contact cells. By moving away from the traditional, costly photolithography process, LONGi's R and D team successfully implemented the all-laser patterning technique, which was key to achieving this new efficiency record.
One of the distinct advantages of HBC cells over conventional bifacial heterojunction solar cells is the reduced need for transparent conductive oxide layers (ITO). LONGi's R and D efforts have led to the development of an ultra-thin TCO layer that significantly lowers indium usage. Remarkably, the indium usage in the 27.09% efficiency record cell is only a fifth of that required for traditional bifacial heterojunction solar cells. This innovation not only enhances efficiency but also contributes to more sustainable and cost-effective solar cell production.
Li Zhenguo, the Founder and President of LONGi, emphasizes the company's dedication to innovation as its core competitive strength. He asserts that "making the best of solar energy to build a green world" is at the heart of LONGi's philosophy. LONGi's commitment to developing high-quality products and high-efficiency solar cell technology is a crucial part of the global energy transition. As Li Zhenguo highlights, photovoltaics are expected to play an instrumental role in this worldwide shift towards renewable energy sources.
