| 摘要 |
The present invention is an electrode material comprising at least, a silver powder, a glass frit, and an organic vehicle, wherein a rate of Ag content of the electrode material is 75 wt % to 95 wt %, and a ratio of contents of Ag grains having an average grain diameter of 0.5 mum to 3 mum and Ag grains having an average grain diameter of 4 mum to 8 mum in the electrode material is (the Ag grains having an average grain diameter of 0.5 mum to 3 mum):(the Ag grains having an average grain diameter of 4 mum to 8 mum)=20-80 wt %:80-20 wt %, and a solar cell comprising an electrode formed by using the electrode material. Thereby, an electrode material that can be stably filled in an electrode groove formed on a semiconductor device and that an electrode with narrow line width and small resistance loss can be easily formed by, and a solar cell with high power having an electrode formed by using the electrode material are provided.
