To provide a method for manufacturing a solar cell, whereby solar cells can be mass-produced by a simple process at low cost. A first conductivity-type silicon powder (11) is prepared, a silicon powder layer (11a) is formed by disposing the powder in the form of a layer, the powder layer is melted by heating the powder layer to the melting point of silicon or higher, and a first conductivity-type silicon layer (11b) is formed by cooling the melted layer. A second conductivity-type silicon powder (12) is prepared, a second conductivity-type silicon powder layer (12a) is formed by disposing the powder in the form of a layer on the first conductivity-type silicon layer (11b), the powder layer is melted by heating the powder layer to the melting point of silicon or higher, and a second conductivity-type silicon layer (12b) is formed by cooling the melted layer. |
