Metallization Paste

Low Temperature Metallization Pastes for Thin Film and c-Si Solar Cells

Also referred to as "grid ink", "silver ink", and "conductive ink", Indium Corporation offers screen printable low-temperature metallization pastes for thin film PV technologies such as CIGS, a-Si and certain c-Si applications.

Low temperature metallization paste is a silver or silver/copper filled front side current collector material used on thin film solar cells. It gets is low-temperature label because it is processed at lower-than-traditional glass frit temperatures of ~1,000°C.

Indium Corporations Low temperature Metallization pastes offer industry leading print performance, contact resistance, and volume resistivity. LT-918 silver filled metallization pastes has been tested against leading commercial metallization pastes and has been proven to optimize print performance and resist cold slump after printing which minimizes shadowing and increases cell effeciency.

LT-918 offers increased Maximum Power performance compared to competitive pastes.
