IBC solar cell based on ultrathin black silicon wafer achieves 16.4% efficiency

A Spanish-Finnish research team has fabricated an IBC solar cell with an ultrathin black silicon wafer with a thickness of 40 µm. The device is based on vanadium oxide and laser-processed phosphorus-doped silicon carbide stacks as hole and electron transport layers, respectively.

Video: ISC Konstanz director predicts 50% global market share for IBC solar panels by 2030

Radovan Kopecek, the co-founder and director of Germany’s ISC Konstanz, says interdigitated back contact (IBC) tech could account for half of the global market for solar modules by 2030. He says IBC will start to dominate once TopCON and HJT get stuck at certain efficiency limits, and he believes TOPCon will be the first victim.

IBC solar modules may drive TOPCon out of market by 2028, says tech expert

Radovan Kopecek, an expert on interdigitated back-contacted (IBC) tech, says that IBC solar panels could capture more than 50% of the global market by 2030, potentially pushing TOPCon products out of competition. He told pv magazine how this transition might materialize and discussed the tech advancements that could make it possible.
