Heliatek Organic Solar Cells Show Promise

In a previous article we discussed the growth opportunity of “building integrated photovoltaics” (BIPV) and highlighted a company addressing this opportunity, Oxford Photovoltaics. Another private European company addressing this same growth opportunity is Heliatek.         About Spun-off in 2006 from the Technical University of Dresden and the University of Ulm, German company […]

Dyesol Supplies Dye Solar Cell Materials

In a previous article titled “Building Solar Cells with Oxford Photovoltaics” we discussed how dye-sensitized solar cells could be used to create economically viable solar windows. In this article, we talked about Professor Michael Gratzel, the solar pioneer who invented dye sensitized solar cells which won him the 2010 Millenium Technology Grand Prize. One publicly traded company that Professor Gratzel resides […]
