A method of forming a fired multilayer stack are described. The method involves the steps of a) applying a wet metal particle layer on at least a portion of a surface of a substrate, b) drying the wet metal particle layer to form a dried metal particle layer, c) applying a wet intercalation layer directly on at least a portion of the dried metal particle layer to form a multilayer stack, d) drying the multilayer stack, and e) co-firing the multilayer stack to form the fired multilayer stack. The intercalating layer may include one or more of low temperature base metal particles, crystalline metal oxide particles, and glass frit particles. The wet metal particle layer may include aluminum, copper, iron, nickel, molybdenum, tungsten, tantalum, titanium, steel or combinations thereof.

Disclosed herein is a composition for solar cell electrodes. The composition includes a conductive powder, a glass frit, and an organic vehicle, wherein the glass frit is a bismuth oxide-tellurium oxide-zinc oxide-lithium oxide-based glass frit comprising: 5 wt % to 20 wt % of bismuth oxide; 55 wt % to 80 wt % of tellurium oxide; 0.1 wt % to 15 wt % of zinc oxide; and 0.1 wt % to 10 wt % of lithium oxide. Solar cell electrodes formed of the composition have low serial resistance (Rs) and high open voltage (Voc), thus providing high conversion efficiency and good adhesive strength with respect to a ribbon.

A feed-through element for harsh environments is provided that includes a support body with at least one access opening, in which at least one functional element is arranged in an electrically insulating fixing material. The electrically insulating fixing material contains a glass or a glass ceramic with a volume resistivity of greater than 1.010.sup.10 cm at the temperature of 350 C.

A solid electrolyte including an alkali metal element, phosphorous, sulfur and halogen as constituent components.

Silver pastes including two powders having different physical properties and silver flakes together with glass frits and pigments impart improved thermal stress characteristics to substrates upon firing.

The present invention relates to a glass material for sealing a large-area dye-sensitized solar cell and, more specifically, to a glass material which does not react with an electrolyte and allows uniform and high-strength binding even on a large area. According to the present invention, the glass material is expected to produce action effects of improving reliability and lifetime of solar cell products since it can uniformly seal a dye-sensitized solar cell, is chemically stable due to the absence of the reaction with an electrolyte, and has physical strength appropriate for large-area binding.
