Title:
PHOTOELECTRIC CONVERSION LAYER COMPOSITION AND PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/017536
Kind Code:
A1
Abstract:
Provided is a composition that can form a photoelectric conversion layer having superior adhesion to a substrate without requiring a sintering step. The composition is configured from at least a semiconductor (for example, titanium oxide particles) and an ionic polymer (for example, a fluororesin having a sulfo group, or the like) and the fraction of the ionic polymer is 0.1-30 parts by weight for every 1 part by weight of the semiconductor. The composition may further contain a dye (sensitizing dye). A photoelectric conversion layer can be formed without sintering a semiconductor by means of the composition coating a conductive substrate.
