Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photovoltaic cells require a support member that provides load-bearing and light-transmission capabilities while maintaining durability and resistance to environmental factors, as existing materials like glass and metal foils have limitations in terms of brittleness and resistance.
Innovation Solution
A sheet for photovoltaic cells comprising a resin layer with a silicon resin and a light resistance agent, including an aryl group, which enhances adhesiveness, moisture resistance, and light collecting efficiency, and can be used as a back sheet with a base layer such as a metal foil or fluorine resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glass or metal foil is used as the bottom layer, then load-bearing capability is improved, but brittleness and resistance to environmental factors worsen
Solution Approach 1:
The patent uses a composite structure consisting of a base layer (glass or metal foil) combined with a resin layer containing silicon resin and light resistance providing agent. This composite material approach allows the base layer to provide load-bearing capability while the resin layer provides environmental resistance, thereby resolving the contradiction between strength and reliability.
2Stability of the object's composition
If a rigid back skin is used as the bottom layer, then structural stability is improved, but flexibility and adaptability worsen
Solution Approach 1:
The patent combines a rigid base layer with a flexible resin layer to create a composite back sheet that exhibits both structural stability and flexibility. The resin layer's viscoelastic properties provide flexibility and adaptability while the base layer maintains structural stability, resolving the contradiction between these two requirements.
3Ease of manufacture
If conventional resin materials are used, then ease of manufacture is improved, but moisture barrier property and light resistance worsen
Solution Approach 1:
The patent changes the chemical composition parameters of the resin by incorporating silicon resin and light resistance providing agents. This parameter change transforms conventional resin into a specialized resin composition that maintains ease of manufacture through standard coating processes while significantly improving moisture barrier property and light resistance.
Solution Approach 2:
The patent creates a composite resin system combining silicon resin with light resistance providing agents, achieving enhanced protective properties while maintaining manufacturability through established coating and curing processes.
