What is IBC solar cell technology? IBC, the full name of Interdigitated Back Bontact, is a new type of solar panel technology. The most notable feature of the IBC solar cell is that the PN junction and metal contact are located on the back of the solar cell, avoiding the shielding of the front metal grid electrode.
