Inverted pyramid-based PERC solar cell with 21.4% efficiency
A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.
Made in China HJT coming to Aussie rooftops
Risen Australia and distributer One Stop Warehouse signed an expanded 150 MW distribution agreement last week, marking the Chinese module maker’s attempt to further expand its share of the rooftop market segment. With Risen’s new heterojunction (HJT) module, the 415-435 W Sieger, moving into mass production, One Stop Warehouse’s Leo Ye says that the “new, fresh” technology will be a welcome addition to the Australian rooftop market segment.
