Title:
LIGHT ABSORPTION LAYER, PHOTOELECTRIC CONVERSION ELEMENT, AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2018/163327
Kind Code:
A1
Abstract:
The present invention relates to a light absorption layer that makes it possible to perform photoelectric conversion in both the visible light region and the near infrared light region and that is for forming a photoelectric conversion element and a solar cell having high conversion efficiency. The present invention also relates to a photoelectric conversion element and a solar cell comprising the light absorption layer. This light absorption layer comprises a perovskite compound and quantum dots containing a halogen element and an organic ligand. The molar ratio of the organic ligand with respect to the metal element constituting the quantum dots is 0.1-0.4.
