    摘要： 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.

    摘要： The space glasses have a composition, in wt. % based on oxide content, including SiO2, 12-45; B2O3, 0-4; Al2O3, 0-4; TiO2, 0-5; PbO, 50-82; Na2O, 0-4; K2O, 0-8; and at least 0.1 wt. % of a total amount of at least three doping agents selected from CeO2, MoO3, Bi2O3, WO3, Ag2O, SnO2, Sb2O3 and As2O3. Light-weight and space-saving optical systems for outer space applications can be made with these space glasses, which have high UV- and VIS-transmittance and high transmittance stability, because of their high radiation resistance based on their dopant content. A preferred process for making the space glass includes melting the above-stated oxide ingredients in a quartz crucible at 1050° C. to 1200° C. to form a melt and refining the melt at 1230° C. to 1350° C.
