Embodiment approach
[0034] According to a typical embodiment of the present invention, the solar cell electrode components include silver powder, sodium tellurite-trilead tetroxide-based glass powder and an organic vehicle. Now, the composition of the solar cell electrode of the present invention will be described in more detail.
[0035] (A) silver powder
[0036] According to a typical embodiment of the present invention, the paste composition for preparing solar cell electrodes contains silver powder as the conductive powder. The particle size of silver powder can be nano or micron. For example, silver powder may have a particle size of tens to hundreds of nanometers, or several to tens of microns. Alternatively, the silver powder may be a mixture of two or more silver powders having different particle sizes.
[0037] Silver powder can have a spherical, flake or amorphous shape.
[0038] The silver powder preferably has an average particle diameter (D50) of about 0.1 μm to about 10 μm, mor...
