Abstract
Solar cell stack-ups are described in which fullerene based transport layers are blended with a metal halide such as LiF, CsF or MgF2. In particular, perovskite solar cell stack-ups are described in which an electron transport layer includes a metal halide and fullerene blend.
Claims24
A solar cell comprising:
- a bottom electrode;
- a bottom transport layer over the bottom electrode;
- an absorber layer over the bottom transport layer;
- a top transport layer over the absorber layer;
- and
- a top electrode layer over the top transport layer;
- wherein the top transport layer includes a metal halide and fullerene blend characterized by a first metal halide concentration closest to the absorber layer and a second metal halide concentration closest to the top electrode layer, wherein the first metal halide concentration is lower than the second metal halide concentration.
