Ceramic glass powder and solar cell metallization paste containing ceramic glass powder
The present disclosure discloses a ceramic glass powder and a solar cell metallization paste containing the ceramic glass powder, and belongs to the technical field of solar cells. The present disclosure provides a novel formula mode of a glass powder including a crystallization nucleus component and a glass network component, that is, a formula of a ceramic glass powder that has a special crystallization behavior, a low crystallinity before sintering and a high crystallinity after the sintering, and a conductive metallization paste containing the ceramic glass powder is further obtained. The present disclosure solves the technical problem that by using metallization pastes in the prior art, a balance between corrosion of a silicon wafer and an ohmic contact is difficult to achieve. The efficiency of a solar cell is improved.

Method of fabricating a glass substrate with a plurality of vias
Pastes are disclosed that are configured to coat a passage of a substrate. When the paste is sintered, the paste becomes electrically conductive so as to transmit electrical signals from a first end of the passage to a second end of the passage that is opposite the first end of the passage. The metallized paste contains a lead-free glass frit, and has a coefficient of thermal expansion sufficiently matched to the substrate so as to avoid cracking of the sintered paste, the substrate, or both, during sintering.
