Title:
PHOTOELECTRIC CONVERSION DEVICE, ELECTRONIC DEVICE, AND POWER SUPPLY MODULE
Document Type and Number:
WIPO Patent Application WO/2023/058490
Kind Code:
A1
Abstract:
A photoelectric conversion device includes a photoelectric conversion layer, and an electron transport layer. The electron transport layer includes metal oxide particles. In response to performing an X-ray photoelectron spectroscopy (XPS) analysis on the electron transport layer, two peaks representing 1s orbitals of oxygen atoms are detected. A formula Y/(X+Y)≧0.5 is satisfied, where a peak area of a peak on a low-energy side among the two peaks is X and a peak area of a peak on a high-energy side among the two peaks is Y.
