Correct me if I'm wrong, but my understanding is that the theory is QDSC can be manufactured at extremely low cost via high-speed R2R printing making QDSC far less expensive to manufacture than Si solar cells. 2) Why do you assume it takes 1g of QD to replace 1g silicon? If it takes 1g QD to make a 60" TV, maybe it only takes 1g to make 1m^2 QDSC? How many g of Si does it take to make 1m^2 of Si solar cells? 3) How do you know that QDs for QDSC will cost the same as for display? Maybe they use less expensive component chemicals, are easier to make, or don't require as stringent specs as display? Maybe they cost a lot less than $100g? Quote:at least 10 years until QD price is compatible to that of polycrystalline silicon, so FF's operation will has no immediate benefit for us at all. With Polycrystalline silicon at 10 cents a gram and quantum dot price at $100 per gram, people must be insane to buy a $250 watt QD PV panel for $1/2 million while the current 250 watt silicon base solar panel are selling at well under $200.
