Title:
PHOTOVOLTAIC ELEMENT, OPTICAL SENSOR, IMAGING ELEMENT, AND FINGERPRINT AUTHENTICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/176829
Kind Code:
A1
Abstract:
The present invention provides a photovoltaic element that exhibits a high photoelectric conversion efficiency. The present invention is a photovoltaic element at least having a positive electrode (2) and a negative electrode (5) and, between the positive electrode (2) and the negative electrode (5), an organic material-containing buffer layer (3) and a photoelectric conversion layer (4), wherein: this organic material comprises an organic material for which the absolute value of the lowest unoccupied molecular orbital LUMO is larger than the absolute value of the work function WF of the positive electrode, and this photovoltaic element does not have a layer comprising a metal oxide between the positive electrode (2) and the photoelectric conversion layer (4).
