He had spent a career figuring out how to deposit chemicals very carefully on substrates, first at Los Alamos National Laboratory and later at the semiconductor machinery companies Novellus and KLA-Tencor.
In fact I believe they are leading the pack in thin-film CIGS companies on flexible substrates.
Many fuel cell technologies are actually based on petrochemical substrates.

Today, the Samsung Advanced Institute of Technology announced that its engineers have successfully created "single crystalline Gallium Nitride on amorphous glass substrates" -- an achievement that would allow the manufacturer to produce jumbo-sized LEDs from normal glass, including window panes.

The researchers developed the solar cells using natural substrates derived from trees and fabricated them on cellulose nanocrystal (CNC) substrates which means the solar cells can be quickly recycled in water at the end of their lifecycle.
These sensors can be manufactured on transparent and flexible substrates like the one pictured above, which allows for various real-world applications -- just use your imagination.
Samsung says this scaled-up approach will allow them to lower production costs relative to most LED manufacturers, which rely on sapphire, rather than glass substrates.

Corning, which makes the ceramic substrates for catalytic converters, had been working on a filter for diesel passenger cars, which are popular in Europe.
The thin film LIB fabricated on a mica substrate with high annealing temperature is transferred onto polymer substrates through a simple physical delamination of sacrificial substrates.
