Reliable, top-quality, high performance innovation

HPBC (Hybrid Passivated Back Contact) is LONGi self-developed and named hybrid passivated back contact cell technology. It is a new generation of high-efficiency cell technology featuring no grid lines on the front side of the cell. This technology enhances the cell's light absorption and photovoltaic conversion capabilities through adjustments to the internal structure process, effectively increasing the module's output power. Currently, the conventional production efficiency of HPBC cells has surpassed 25.5%, and the efficiency of HPBC+ cells has exceeded 25.8%, marking it as a revolutionary high-efficiency battery technology.

Bifacial modules collect solar energy from both the front and back side of the module, increasing the total power output per module. GRW Solar had scaled up high-volume manufacturing of bifacial modules and has become the largest producer of bifacial PV products, with cumulative shipments of bifacial modules surpassing 20GW in early 2021.

Higher power & higher reliability: Half-cut technology adopts the IR laser to cut the high efficiency cells from one to two to halve the current. Finally, the heat losses on fingers will be reduced significantly and module efficiency could be increased by 2%. Working current reduction of cell increased module reliability at the same time, especially bifacial cells with higher working current.

Leader of mono crystalline silicon technology: GRW Solar has pioneered in diamond slicing wafer technology, which maximizes wafer output from the square rods and facilitated the M2 standards formation in this industry. In 2019 and 2020, the M6 and M10 standardized wafers were introduced successively, and these have driven down the cell and module production costs as well as BOS. Eventually, maximized values will be brought to the customers.
