Xi''an, December 18, 2023-The world-leading solar technology company, LONGi Green Energy Technology Co., Ltd. (hereafter as "LONGi"), announced today that it has set a new world record of 27.09% for the efficiency of crystalline silicon …
Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.
In 2017, Kaneka Corporation in Japan realized heterojunction back contact (HBC) solar cell with an efficiency of up to 26.7% (JSC of 42.5 mA·cm −2) 25, 26, and recently, LONGi Corporation in China has announced a new record efficiency of 27.30% 16.
The indium usage of the 27.09% efficiency record cell is only 1/5 of that of traditional bifacial heterojunction solar cells. “Innovation is the core competitiveness of enterprises and LONGi is committed to 'making the best of solar energy to build a green world'.
Provided by the Springer Nature SharedIt content-sharing initiative Crystalline-silicon heterojunction back contact solar cells represent the forefront of photovoltaic technology, but encounter significant challenges in managing charge carrier recombination and transport to achieve high efficiency.
The interconnection of SHJ cells is a stumbling block for the whole process chain: soldering, which is used for the interconnection of conventional c-Si cells, is not compatible with LTC Ag paste, which has to be applied instead of the standard fire-through silver paste because of temperature restrictions for the a-Si/c-Si heterojunction.
In this study, we produced highly efficient heterojunction back contact solar cells with a certified efficiency of 27.09% using a laser patterning technique. Our findings indicate that recombination losses primarily arise from the hole-selective contact region and polarity boundaries.

For efficient c-Si heterojunction solar cells, especially these dopant-free passivating contact materials we are going to discuss in Section 4, it is necessary that the Fermi energy of the electron-selective contact is at higher energies than the conduction band minimum of c-Si. Similarly, the Fermi energy of the hole-selective contact has to be lower than the …
