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.
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.
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.

Silicon heterojunction devices rely on the use of thin‐film silicon coatings on either side of the wafer to provide surface passivation and charge carrier‐selectivity. Beyond traditional indium tin oxide, multiple higher‐mobility indium‐based transparent conductive oxides have been employed successfully in HJT cells.
