LTCC devices are produced from dielectric compositions comprising a mixture of precursor materials that, upon firing, forms a dielectric material comprising a matrix of titanates of alkaline earth metals, the matrix doped with at least one selected from rare-earth element, aluminum oxide, silicon oxide and bismuth oxide.

Mid-K LTCC compositions and devices

Paste compositions, methods of making a paste composition, photovoltaic cells, and methods of making a photovoltaic cell contact are disclosed. The paste composition can include a conductive metal component such as aluminum, phosphate glass, phosphorus compounds such as alky! phosphate, and a vehicle. The contact can be formed on a passivation layer on a silicon wafer by applying the paste on the passivation layer and firing the paste. During firing, the metal component can fire through the passivation layer, thereby electrically contacting the silicon substrate.

High thermal conductivity dielectric materials systems or pastes are useful on aluminum alloy substrates for LED and high power circuitry applications.

Dielectric pastes for aluminum substrates

A dielectric coating material system for use in a single-sided back contact solar cell is disclosed. The material system serves to electrically isolate electrodes of opposite polarity types on the same side of a silicon-based solar cell, and includes titanium and phosphorus.
