The above ESL materials are representative of the most common market requirements. The front-side and back-side silvers are available in a number of versions, depending on factors such as the type of silicon (single crystal, poly- or multi-crystalline, etc.), the nature of the anti-reflective coating (silicon nitride, titanium dioxide, etc.) and the paste application method (screen printing, etc.).
