Kind Code:
A1
Abstract:
Provided is a solar cell which has improved photoelectric conversion efficiency.
A solar cell (1) is provided with a photoelectric conversion part (10), a transparent oxide layer (18), a p-side electrode (19p), and an n-side electrode (20n). The photoelectric conversion part (10) has first and second main surfaces (10a, 10b). The first main surface (10a) comprises a p-type surface (10ap) and an n-type surface (10an). The transparent oxide layer (18) is continuously provided on the p-type surface (10ap) and the n-type surface (10an). The sheet resistance of the transparent oxide layer (18) is 1 MΩ/□ or more. The p-side electrode (19p) is arranged on a portion of the transparent oxide layer (18), said portion being positioned above the p-type surface (10ap). The n-side electrode (20n) is arranged on a portion of the transparent oxide layer (18), said portion being positioned above the n-type surface (10an).
