Japanese Patent JP7088811

B2

The present invention provides a method for forming an electrode on a semiconductor substrate such as a solar cell with an insulating film interposed therebetween, in which the generation of particulate matter in the electrode is suppressed and the appearance of the obtained electrode is improved. The present invention relates to a glass capable of improving the conversion efficiency of a solar cell while ensuring the reliability of a product, a glass powder comprising the glass, a conductive paste containing the glass powder, and a solar cell having improved conversion efficiency by using the conductive paste. The glass is characterized by being represented by mol% in terms of oxides. The invention discloses a B2O3-Bi2O3-ZnO microwave dielectric ceramic, which comprises the following components in percentage by weight: 40 to 60 percent of B2O3, 5 to 25 percent of Bi2O3, 20 to 30 percent of ZnO, 2 to 7 percent of SiO2, 1 to 10 percent of Sb2O3 and 0 to 10 percent of BaO, the glass powder is composed of the glass and has a D50 of 0.5-6.0 [mu] m when D50 is the 50% volume-based particle size in the cumulative particle size distribution.
