PERC solar cell

Upside down pyramid-based PERC solar cell with 21.4% efficiency
A Chinese research study group has developed a PERC cell on an industrial 180-μm-thick monocrystalline silicon wafer with a typical 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 also a fill factor of 80.30%.
