A strengthened glass sheet product as well as process and an apparatus for producing the product. The process comprises cooling the glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened glass sheets having improved breakage properties.

Example embodiments relate to a composition for forming a solar cell electrode, and a solar cell electrode prepared using the composition. The composition for forming a solar cell electrode includes a silver (Ag) powder, a glass frit, and an organic vehicle, wherein the glass frit includes silver (Ag); tellurium (Te); and at least one selected from the group of lithium (Li), sodium (Na), and potassium (K), a molar ratio of the silver (Ag):the tellurium (Te) included in the glass frit is in a range of about 1:0.1 to about 1:50, and a molar ratio of the silver (Ag):lithium (Li), sodium (Na) or potassium (K) is in a range of about 1:0.01 to about 1:10. The solar cell electrode prepared using the composition has excellent fill factor and conversion efficiency due to minimized contact resistance (Rc) and series resistance (Rs).
