    In this work, p- and n-type Si pastes were prepared in a way by utilizing a planetary ball miller to pulverize Si source material. pn homojunction was formed by coating Si pastes onto metal substrates, followed by annealing under Ar or Ar + H 2 atmosphere. The optimal annealing temperature was found to be around 1050 °C that exhibits the lowest resistivity. A typical rectifying property of diode with small photovoltaic was observed for the device fabricated. It is anticipated that Si pastes could have potential for low cost device fabrication such as solar cells. All Cz Si ingot growth procedures could be skipped, consequently it is expected that the manufacturing cost for solar cell can be greatly reduced.
