Abstract
The present disclosure is a conductive paste for a solar cell electrode comprising a metal powder, a glass frit, and an organic vehicle, wherein the discharge amount factor A of the bus-bar electrode can be calculated by Equation 1 below, and the discharge amount factor B of the finger electrode can be calculated by the following Equation 2, and |AB| relates to a conductive paste for a solar cell electrode, characterized in that it is 0.100 or less. A=(Slip velocity×10)/(G′×0.01) [Equation 1] B=1/(G″×0.01) [Equation 2]
Claims6
A conductive paste comprising a metal powder, glass frit, and an organic vehicle, wherein factor A is calculated by Equation 1 below, factor B is calculated by Equation 2 below, and |A−B| is 0.100 or less
- A=(Slip velocity×10)/(G′×0.01) [Equation 1]
- B=1/(G″×0.01) [Equation 2]
- (wherein, G′ means the elasticity value when the shear strain is 1%, and G″ means the elasticity value when the shear strain is 90%).
