PEROVSKITE SOLAR CELL USING DIFFUSION BARRIER FILM AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/079943

Kind Code:

A1

Abstract:

The present invention relates to a perovskite solar cell and a manufacturing method therefor, and the perovskite solar cell according to the present invention comprises: a first electrode (10) formed as a transparent conductive substrate; a second electrode (20) formed of metal and facing the first electrode (10); a light absorption layer (30) formed such that a perovskite material is disposed between the first electrode (10) and the second electrode (20); a hole transport layer (40) disposed between the light absorption layer (30) and the second electrode (20); and a diffusion barrier layer (50) disposed between the light absorption layer (30) and the hole transport layer (40) so as to prevent ions in the light absorption layer (30) from being dispersed into the hole transport layer (40).
