SOLAR CELL, MANUFACTURING METHOD THEREFOR AND SOLAR CELL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solar cell using carbon nanotubes which can enhance photoelectric conversion efficiency.SOLUTION: In a solar cell 1 where a power generation layer consisting of carbon nanotubes CNT is disposed between a metal electrode 11 and a transparent electrode 16, the power generation layer is formed by laminating an n-type carbon nanotube layer 12 formed by adding an element A of small electronegativity to carbon nanotubes, and a p-type carbon nanotube layer 13 formed by adding an element B of large electronegativity to carbon nanotubes.
