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.

The specification discloses a method for containing spills on shelving and the like, and the resulting support members made in accordance with the method, by providing the generally flat top surface of a support with a hydrophobic surface which is arranged in a spill containment pattern and which is generally in the plane of the top surface of the support. The majority of the top surface of the support consists of one or more spill containment areas which are of a non-hydrophobic nature and which are bounded by the hydrophobic surfaces, such that spills on the shelving collect in the non-hydrophobic spill containment area or areas and are prevented from spreading by the hydrophobic surfaces.
