Take a look at thislecture by Prof. Kymakis (Barcelona, February 20-23, 2018, http://nano.teicrete.gr/ , https://nanobioconf.com/ ). It contains a lot of very interesting information.Before outdoor tests were carried out on PV modules, they were previouslyextensively tested in test chambers. Greatcell should bring a mature product tomarket. Otherwise, we shareholders will not enjoy the long term. The worldneeds this technology. That's why I have so much patience.
Greatcell is on track!
