SolarWindow Technologies, Inc. (WNDW)

you should check these guys out: www.onyxsolar.com.
there are others, but this one is the best example of a company that has long been doing what WNDW has been promising but never delivers on, actually commercializing. they also have some large clients and did some very big projects in the US (for example the Miami Heat Stadium). This is photovoltaic glass for buildings, not just a few square cm of it. they have huge R&D and actually generate turnover; not just two guys in white coats being paid a 100K each to be part of a stock scam.
