Transparency Materials Still Less Than 70% Clear

However, a team of researchers in Japan have now made promising steps toward solving this transparency issue

The process is based on a conductive material called Indium Tin Oxide (ITO), which is both transparent and colorless.

ITO is one of the most widely used transparent conducting oxides because of its electrical conductivity and optical transparency, the ease with which it can be deposited as a thin film, and its chemical resistance to moisture.

(Completely unrelated and 99.9% different, but this reminds me of newer bulletproof glass technologies. The .1% being that they’re both clear.)
