Patent ID: 7947893

Claim:
A solar cell characterized by comprising: a photoelectric conversion part ( 101 ) having a concave and convex profile in a light receiving surface thereof; and a protective layer ( 10 ) which is provided to cover the concave and convex profile, and which includes particles therein, and which has a concave and convex profile in both surfaces thereof, the solar cell characterized in that in a cross section, in parallel with an incident direction of light, of the protective layer ( 10 ), the number of the particles ( 11 ) contained in a second region is smaller than the number of the particles ( 11 ) contained in a first region, the second region being centered at a convex portion of the concave and convex profile, and having a unit length, the first region being centered at a concave portion of the concave and convex profile, and having the unit length.
