PROBLEM TO BE SOLVED: To provide a laminated photovoltaic element at low cost, while being high in reliability and photoelectric transfer efficiency. SOLUTION: A plurality of component elements of pin joint made of a p-type layer of silicon-based non single-crystal semiconductor, an i-type layer, and an n-type layer are laminated, while an amorphous silicon is used as the i-type layer of a first pin joint on light-incident side, a microcrystal silicon is used as the i-type layer of a second pin joint, and a microcrystal silicon is used a the I-type layer of third pin joint. |
