SunPower has indeed achieved efficiencies above 23%. There is however a difference with the imec technology. Imec achieved these efficiencies using more traditional low-cost technologies and aims at a more sustainable technology by using Cu metallization.

Yes, I think SunPower Corporation anounced acheiving 24.2% efficiency in June this year? But I'm not sure if the eficiency was claimed on one batch in production or whether they improved something in the design and/or the manufacturing process in order to acheive 24.2% efficiency. Anyways, I feel there is a need of a major "break-through" in this technology to increase the efficiency to a cost-effective level.

I think this is not the highest efficiency obtained for solar cells, as SunPower Corp. has produced a full-scale solar cell with a sunlight to electricity conversion efficiency of 24.2 percent at its manufacturing plant in the Philippines. This is a new world record for large area silicon wafers, and has been confirmed by the U.S. Department of Energy's National Renewable Energy Lab (NREL). But still it is required that everyone in the solar segment grows with better result, that way the world will be competative.
