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.
