About My Country's Progress In Solar Cell Efficiency

    A breakthrough has been made in the highest efficiency of crystalline silicon solar cells in my country. The efficiency of polycrystalline silicon PERC cells increased from 22% to 22.8%, the efficiency of monocrystalline silicon PERC cells increased from 23.1% to 24.03%, the efficiency of HIT cells increased from 23.7% to 24.85%, and the efficiency of TOPCon cells increased from 23.1% to 24.58%. The efficiency of GaAs cells increased from 28.8% to 29.1%, the efficiency of CIGS cells on glass substrates increased from 21.2% to 22.92%, the efficiency of perovskite single-junction cells increased from 23.32% to 23.7%, and the efficiency of perovskite micromodules increased from 16% increased to 17.25%.

    According to relevant reports, Canadian Solar has created a polysilicon PERC cell with the highest efficiency of 22.8% in China, and also created a world record for the efficiency of polysilicon cells. LONGi has created the highest efficiency in China of 24.03% for monocrystalline silicon PERC cells.

    In terms of the efficiency of thin-film solar cells, Hanergy has created the highest efficiency of 29.1% single-junction GaAs cells in China, which is also the world's highest efficiency record for single-junction GaAs cells. At the same time, Hanergy also created the highest efficiency of 22.92% for copper indium gallium selenide cells on glass substrates, and the highest efficiency in China of 20.56% for copper indium gallium selenide cells on flexible substrates.
