Abstract
The present invention enables on-demand production of an organic photoelectric conversion element regardless of the timing of material synthesis. Provided is a method for producing an organic photoelectric conversion element that comprises a pair of electrodes including an anode and a cathode, and an active layer that is provided between the pair of electrodes and includes a π-conjugated polymer, said method including a storing step of storing the π-conjugated polymer in an enclosure container which has an atmosphere therein that suppresses increase in the electron spin concentration of the π-conjugated polymer, and a step of forming the active layer using the π-conjugated polymer after storage.

A method for producing an organic photoelectric conversion element that comprises a pair of electrodes including an anode and a cathode, and an active layer that is disposed between the pair of electrodes and includes a π-conjugated polymer, the method comprising:
- a storing step of storing the π-conjugated polymer in an enclosure container which has an atmosphere therein that suppresses increase in the electron spin concentration of the π-conjugated polymer;
- and
- a step of forming the active layer using the π-conjugated polymer after storage.
A reagent package comprising:
- a π-conjugated polymer for forming an active layer of an organic photoelectric conversion element;
- an enclosure container enclosing the π-conjugated polymer in an airtight state, in which the enclosure container has gas barrier properties and the π-conjugated polymer can be enclosed in and taken out of the enclosure container;
- and
- an oxygen absorber that is provided so as to come into contact with the atmosphere in the enclosure container in an airtight state, wherein the atmosphere is an atmosphere having an oxygen concentration of 1% or less.
A storage method comprising a storing step of storing a π-conjugated polymer in an enclosure container which has an atmosphere therein that suppresses increase in the electron spin concentration of the π-conjugated polymer.
