Title:
ORGANIC PHOTOELECTRIC CONVERSION ELEMENT AND ORGANIC THIN-FILM SOLAR BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2017/065251
Kind Code:
A1
Abstract:
The present invention provides an organic photoelectric conversion element and organic thin-film solar battery module capable of adjusting the exterior color of a solar battery surface to a bluish color regardless of the color tone of an organic active layer, thereby enhancing design without impeding the solar battery characteristics and while preventing the solar battery from exhibiting the color of yellow or red.
The organic photoelectric conversion element comprises a transparent substrate, a lower transparent electrode including a metal layer, an organic active layer, and an upper electrode which are successively layered, and is characterized in that an optical path length (n × d) between the transparent substrate and the metal layer which is expressed by a distance d between the transparent substrate and the metal layer and a refractive index n satisfies the following expression (1):
480 nm ≥ 4 × (n × d) / (2 × m + 1) ≥ 380 nm (1)
where m is an integer of zero or more.
