Abstract
The present invention is related to a solar cell comprising a first electrode; a second electrode; and a stack of layers provided between the first electrode and the second electrode; wherein the stack of layers comprises one light absorbing layer provided with a perovskite crystal structure; and at least one dopant layer, wherein the dopant layer consists of one or more n-dopant material(s); or one or more p-dopant material(s).
Claims13
A solar cell comprising:
- a) a first electrode having a first surface and a second surface opposite the first surface;
- b) a second electrode having a first surface and a second surface opposite the first surface;
- and
- c) a first stack of layers provided between and in direct contact with the first surface or the second surface of the first electrode and the second electrode or the first surface, respectively, of the second electrode;
- wherein the first stack of layers comprises
- (c1) one light absorbing layer provided with a perovskite crystal structure;
- and
- (c2) a dopant layer, wherein the dopant layer consists of an n-type dopant material(s),
- the first stack of layers comprises only n-type dopant layers and does not comprise p-type dopant layers;
- the dopant layer is arranged between the first electrode and the light absorbing layer.
