摘要:
The present disclosure relates to fusion formable highly crystalline glass-ceramic articles whose composition lies within the SiO2—R2O3—Li2O/Na2O—TiO2 system and which contain a silicate crystalline phase comprised of lithium aluminosilicate (β-spodumene and/or β-quartz solid solution) lithium metasilicate and/or lithium disilicate. Additionally, these silicate-crystal containing glass-ceramics can exhibit varying Na2O to Li2O molar ratio extending from the surface to the bulk of the glass article, particularly a decreasing Li2O concentration and an increasing Na2O concentration from surface to bulk. According to a second embodiment, disclosed herein is a method for forming a silicate crystalline phase-containing glass ceramic.

摘要:
Photovoltaic devices having light scattering articles having a smooth surface are described herein. Glass frits on glass superstrates can provide planar surfaces for subsequent layer deposition such as TCO layers and yet provide light scattering functions within, for example, silicon tandem photovoltaic devices. Methods of making the light scattering articles with a planar surface include depositing unfilled or filled glass frits on planar or surface-textured superstrates and sintering of the glass frit. The compositions of the glass frits can be tailored to match, for example, the expansion properties and physical properties of the glass superstrates.
