The tiny silicon wires stick up from the base,or substrate, looking something like a microscopic hair brush.

In addition, the OLEDs can be fabricated onto a flexible plastic substrate rather than a rigid glass layer, making it easier to manufacture them into a curved screen.
Suntech Power is currently pursuing thin film technology, a low cost PV technology that involves depositing several thin layers of silicon or more complex materials on asubstrate such as glass to make a PV cell.
Material for each color is deposited on the substrate through a fine metal mask, with one mask used for each color so that colors line up in a precise, very close pattern that, to the human eye, appears to create one pixel, or point of light.
