Heterojunction technology (HJT) is a not-so-new solar panel production method that has really picked up steam in the last decade. The technology is currently the solar industry’s best option to increase efficiency and power output to their highest levels.
The technology is currently the solar industry’s best option to increase efficiency and power output to their highest levels. HJT combines the best qualities of crystalline silicon with those from amorphous silicon thin-film to produce a high-power hybrid cell that surpasses the performance of the industry’s go-to technology, PERC.
SANYO (now Panasonic) developed the HJT production concept in the 1980s. The earliest HJT modules were 14.4% efficient and produced 170 W. Today, HJT modules can reach efficiencies of up to 25%. How does HJT work? Heterojunction solar panels are composed of three layers of photovoltaic material.
Heterojunction technology (HJT) is a solar panel production method that has been on the rise since last decade. It is currently the solar industry’s most effective process for increasing efficiency and power output to the highest levels.
Heterojunction technology (HJT) is a solar panel production method that has been on the rise since last decade. It is currently the solar industry’s most effective process for increasing efficiency and power output to the highest levels. It even surpasses the performance of PERC, the solar industry’s current go-to technology.
The HJT production concept was developed by SANYO Electric in the 1980s (SANYO was acquired by Panasonic in 2009). SANYO was the first company to commercially produce solar cells made of amorphous silicon (a-Si).
