Dopant material, a semiconductor substrate, a solar cell element, and a manufacturing method of the dopant material

Productivity good dopant material, also a semiconductor substrate manufactured using the dopant material, further provides a method of manufacturing a solar cell element, and the dopant material. Dopant material according to the present embodiment, a dopant material is added to the semiconductor material comprising silicon, comprising an element to be an n-type or p-type dopant source, and a polycrystalline silicon. Then, the concentration of the element which serves as the dopant source is 1 ×
