Lithium-Tellurium Silicon-Lead Bismuth Multi-component Glass-Oxide-Complex System and Conductive Paste Containing Same
The present disclosure discloses a lithium-tellurium silicon-lead bismuth multi-component glass-oxide-complex system and conductive paste containing same, belonging to the technical field of solar cells. According to the present disclosure, a “functional modularization” strategy is adopted in a formula design of the glass-oxide-complex system, and glass oxide systems with selective reactivity for different passivation layers are compounded based on the structures, compositions and thicknesses of the passivation layers, so that a paste formula is developed, which is composed of lithium-containing, tellurium-silicon-containing and lead-containing glass oxides. Due to adoption of the modularized formula strategy, active ingredients can be better controlled, and the overall paste formula is more optimized, so that the laminated passivation layers can be selectively burned through to obtain a more balanced contact, and better battery performance on silicon wafers with different passivation layer thicknesses can be achieved, thus achieving excellent photoelectric conversion efficiency.

METHOD OF FORMING A TRANSPARENT CONDUCTIVE MEMBER, AND A FREE-STANDING TRANSPARENT CONDUCTIVE FILM
Devices, systems, and methods related to a transparent conductive film are disclosed. In one aspect, a method of forming a transparent conductive member (e.g., a transparent conductive film) includes extruding a metallic nanoparticle composition from a capillary tube onto a temporary substrate to form an extrudate. The extrudate can include metallic nanoparticle lines. The method further includes sintering the extrudate and the temporary substrate, dispensing a photocurable polymer onto the temporary substrate, and laminating a second substrate to the photocurable polymer. The photocurable polymer and the extrudate are interposed between the temporary substrate and the second substrate. The method further includes curing the photocurable polymer to form a transparent polymer layer and separating the temporary substrate from the transparent layer to form the transparent conductive member. The transparent conductive member includes the transparent polymer layer and the extrudate embedded in the transparent polymer layer.

Metal powder sintering paste and method of producing the same, and method of producing conductive material
There is a problem that when a silver powder sintering paste that is substantially free from resin is used, an organic solvent used as a dispersion medium bleeds, which results in contamination and wire bonding defects. In order to solve the problem, provided is a metal powder sintering paste that contains, as a principal component, silver particles having an average particle diameter (a median diameter) of 0.3 μm to 5 μm and further contains an anionic surfactant but is substantially free from resin.
