摘要:
A finger electrode for a solar cell formed using a conductive paste comprising a conductive powder, a glass frit, and an organic vehicle. A linewidth A′ of the finger electrode at a point 0.5H satisfies the following Equation 1: 0.5A≤A′≤0.75A where H is the height of the finger electrode and A is the linewidth of a base of the finger electrode.
摘要:
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).
