I agree with your first statement. I am not so sure about the second one. Natcore has told us that the solar cell producers have different needs. With a lab AR-Box Natcore can create different formulations to meet those needs. Also, the lab AR-Box is intended to be a trial piece of equipment. Natcore will incorporate what they learn from this AR-Box into the industrial version. If there is an issue with production for instance, it will be corrected in the industrial version. Natcore has been seeking imput from MX and Phono regarding the industrial version, which will be over 3 times larger than the lab version, 960 cubic ft from 288 cubic ft:
Production will be conducted in two phases. The first phase, estimated to take approximately 8–10 weeks, will result in a manual development system, measuring about 8 ft. x 6 ft. x 6 ft., that will allow Natcore scientists to refine the coating process. At that point, Natcore scientists and MicroTech engineers will determine what changes need to be made and how much automation they want to add in the second and final phase. The final production system will measure about 20 ft. x 6 ft. x 8 ft. high. It will be a self-contained modular system capable of recycling its own effluents and of producing 3,000 AR-coated wafers/hour. http://tmx.quotemedia.com/article.php?newsid=39587458&qm_symbol=NXT:CA
It is my understanding that the lab AR-Box will also be used to develop other applications outside of solar.
