I wonder if the often mentioned cooperation with German car plants is only a fiction. There is a report of a forwarding agent (unfortunately in German language), that the company ASOLA (I mention it about one month ago) is closely working with BMW in developing the new solar roof of the e-car. ASOLA is already delivering the solar roof for Mercedes Smart and Fisker Kama. And ASOLA is closely working with Audi for the same part. May be, BWM is also testing the DSC-technology with Dyesol, but it seems for me, that ASOLA makes the run, because more and more article can be read in conjunction of BWM and ASOLA.
