Claim 0:
1. A hybrid organic-inorganic solar cell, comprising:
a) a substrate;
b) a transparent conductive oxide (TCO) layer deposited on said substrate;
c) an electron transport material (ETM) layer, wherein said ETM layer comprises an n-type layer;
d) a hole transport material (HTM) layer wherein said HTM layer comprises a p-type layer;
e) at least one passivating barrier layer;
f) a perovskite layer, wherein said perovskite layer comprises an i-type layer; and
g) an electrode layer;
wherein said substrate, said TCO layer, said ETM layer, said perovskite layer, said HTM layer and said electrode layer are arranged in an n-i-p stack;
wherein said at least one passivating barrier layer is on the perovskite layer and disposed (i) between said perovskite layer and said HTM layer, or (ii) between said perovskite and said ETM layer, or (iii) between said perovskite and said HTM layer, and between said perovskite layer and said ETM layer, or (iv) between said TCO layer and said ETM layer, and between said ETM layer and said perovskite layer, and between said perovskite layer and said HTM layer, or (v) between said substrate and said TCO layer, and between said TCO layer and said ETM layer, and between said ETM layer and said perovskite layer, and between said perovskite layer and said HTM layer,
wherein said at least one passivating barrier layer comprises a material selected from the group consisting of Al2O3, SnO2, ZnO, and NiOx, and
wherein the at least one passivating barrier layer is configured to seal off the perovskite layer.
