Hi Bernard .
The numbers look fantastic .Dyesol only needs to get a small portion of that revenue and it will multiply in price .Thats before any of their other applications are accounted for .
Some of the minor metals that solar companies use like Tellurium may limit their production at some stage .
This is from Jack Lifton .

First Solar Corporation in Ohio makes cadmium telluride thin film photovoltaic cells; the cadmium comes from zinc, and the tellurium comes from copper. Therefore, the reduction in base metals production has also reduced the production of the key minor technology metals used for solar—and there is no substitute. So right this minute we’re in the situation of running on inventory, which is not large, and recycling is almost non-existent for these materials because their uses are dissipated.
