Abstract (en)

Disclosed herein are pastes for solar cell electrodes exhibiting superior printability and conversion efficiency. The paste includes (a) a conductive powder, (b) a glass frit, (c) an organic vehicle, and (d) metal oxide particles comprising nanometer scale particles having an average particle diameter (D50) of 15 to 50 nm and micron scale particles having an average particle diameter (D50) of 0.1 to 2 µm. The present invention also discloses an electrode formed of the paste for solar cell electrodes, and a solar cell comprising the electrode, which has improved paste printability while exhibiting superior conversion efficiency.
