PURPOSE: A paste composition is provided to improve aspect ratio of a front electrode and to reduce resistance of the front electrode by simultaneously using conductive micropowder and conductive nanopowder. CONSTITUTION: A paste composition comprises conductive powder, glass frit, and an organic vehicle. The conductive powder includes conductive micropowder and conductive nanopowder. The size of the conductive nanopowder is 500-1300 nm. The solar cell includes a silicon substrate(10), a front electrode(12) formed on the silicon substrate, and a back electrode(13) formed on the silicon substrate. The front electrode includes silver powder. |
