Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photoelectric conversion elements with a surface protection portion on the electrode detach when bent, leading to decreased durability during storage.
Innovation Solution
Incorporating a surface protection portion adjacent to one electrode using a fluorine-based silane compound to prevent direct contact between the electrode and the sealing member, enhancing durability by preventing detachment and corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surface protection portion is provided on the electrode to prevent corrosion and deterioration, then durability during storage is improved, but the electrode detaches when bent
Solution Approach 1:
The patent changes the material parameter of the surface protection portion from conventional materials to fluorine-based silane compounds. This material substitution modifies the chemical and physical properties of the protection layer, providing both corrosion resistance and flexibility to prevent electrode detachment during bending operations.
Solution Approach 2:
The patent employs composite material structure by combining fluorine-based silane compounds with the electrode surface. This composite approach creates a protective layer that integrates both protective functions (corrosion resistance) and mechanical flexibility (anti-detachment), resolving the contradiction between durability and adhesion strength.
2Object-affected harmful factors
If a surface protection portion is provided to prevent direct contact between electrode and sealing member, then anti-corrosion performance is improved, but flexibility and bending resistance decrease
Solution Approach 1:
The patent modifies the material parameters of the surface protection portion by using fluorine-based silane compounds instead of conventional protection materials. This parameter change enables the protective layer to maintain both anti-corrosion properties and bending flexibility, allowing the photoelectric conversion element to withstand flexing without compromising electrode protection.

AI summary
A photoelectric conversion element includes a first electrode (13), a photoelectric conversion layer (16) over the first electrode, and a second electrode (18) over the photoelectric conversion layer. The photoelectric conversion element further includes a surface protection portion (19) adjacent to a face of one electrode selected from the first electrode and the second electrode where the face does not face the photoelectric conversion layer. The surface protection portion contains a compound derived from a fluorine-based silane compound.
