  High-efficiency Concentrator | Fote Machinery

  200511 · The front-surface-field (FSF) solar cell has a high-low junction on the front side of the IBC solar cell. The function of the front surface field is to reduce the effective front-surface recombination velocity for the carriers in the bulk of a device. Point-contact solar cells are IBC cells with a reduced emitter area and reduced metal contact ...
