ZEBRA with 23+% and MoSoN with (22% and) 690mV!!

 

Our solar cell concepts are all based on cost effective standard processes such as tube furnace diffusions, PECVD SiNx and screen printing. In addition we are using the remaining Boron glass after BBr3 diffusion to passivate the surface. Therefore our cell concepts are extremely cost effective.

Our IBC solar cell ZEBRA reached 23.2% and our MoSoN cell (hybrid PERC/PERT cell) 22% with a Voc of 690mV. This is, to our best knowledge, the best Voc ever reached by simple screen printing.
