The present invention relates to a conductive paste and a method for producing solar cell by using the same. The conductive paste comprises at least silver powders and a composite glass frit comprising a first type of glass frit containing lead oxides and silicon oxides and a second type of glass frit containing tellurium oxides and zinc oxides wherein the first type of glass frit and the second type of glass frit are in a weight ratio of 93:7 to 44:56.

A method of manufacturing an electrode for a solar cell includes printing a conductive paste on a front surface of a substrate using a printing mask having an opening rate of 65% or more, and baking the printed conductive paste. The conductive paste may include a conductive powder, a glass fit, and an organic vehicle, the glass fit may include lithium oxide and tungsten oxide, and, in the glass fit, a weight ratio of lithium oxide to tungsten oxide may be about 0.5 to about 5.5.

The present invention relates to a conductive paste composition for a solar cell electrode, including a conductive metal powder, a glass frit and an organic vehicle, wherein the glass frit has a specific composition that enables the formation of a side shape in which a surface slope, measured depending on the height relative to a wafer, increases and then decreases, and upon electrode formation using the conductive paste including such a glass frit, wetting characteristics and spreadability are improved such that the light-receiving area of a solar cell is enlarged, thus increasing short-circuit current, and contact resistance is also improved to thus increase a fill factor (FF), ultimately increasing the power generation efficiency of the solar cell.

The present disclosure relates to a glass having a refractive index of at least 1.7 as well as the use of the glass as a cladding glass of a solid-state laser. The disclosure also relates to a laser component comprising a core of doped sapphire and a cladding glass being placed on said core. The cladding glass is arranged on said core such that light exiting from the core due to parasitic laser activity can enter the cladding glass and can be absorbed there. Thus, a laser component with improved efficiency is obtained. The present disclosure also relates to a method for producing the laser component.
