Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing optoelectronic components, such as solar cells, are complex and inefficient in achieving electrical interconnection between components.
Innovation Solution
A method involving the introduction of electrically conductive wires or threads into optoelectronic layers, allowing for simple electrical connection and subdivision of optoelectronic components, enabling continuous production of serially interconnected components by using a web or tube-shaped conductive material that is unwound from a roll and integrated into the layer before curing, facilitating contact without contamination or additional cleaning steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires or threads are introduced into the layer before curing, then electrical connection between optoelectronic components is achieved, but the production process becomes more complex
Solution Approach 1:
The wire or thread is introduced into the layer before curing, while the layer is still in a plastic state. This preliminary action allows the wire to be easily positioned and integrated into the layer structure, establishing electrical connections between optoelectronic components before the layer hardens. This resolves the contradiction by enabling reliable electrical connection through early integration, while the pre-planned positioning actually simplifies rather than complicates the overall process.
Solution Approach 2:
The wire or thread acts as an intermediary element that penetrates through the layer to establish electrical contact between front and rear contacts of adjacent optoelectronic components. This intermediary approach provides a straightforward method for achieving series connections without requiring complex external wiring or post-processing steps, thereby improving reliability while maintaining process simplicity.
2Ease of manufacture
If the wire protrudes from the layer surface, then electrical contacting is simplified, but the wire may be contaminated by layer material
Solution Approach 1:
The wire is introduced into the layer before curing, and its protruding portions are positioned to extend beyond the layer boundaries. This preliminary positioning allows the wire to emerge from the layer surface in a controlled manner, enabling straightforward electrical contacting. The timing of wire introduction ensures that protruding sections remain accessible for contact establishment without being embedded in cured material.
Solution Approach 2:
Instead of trying to contact wires after they are embedded in cured material (which would be difficult), the method inverts the approach by having wires protrude from the layer surface before curing. This inversion makes the wires naturally accessible for electrical contacting, simplifying the manufacturing process. The wire configuration is reversed from the conventional embedded approach to an protruding approach, solving the accessibility problem.
3Productivity
If a web-shaped conductive material is used for continuous production, then productivity increases, but the method becomes less adaptable to different production scales
Solution Approach 1:
The patent employs web-shaped or tube-shaped conductive materials that can be unwound from rolls, enabling continuous production processes. This parameter change from discrete wire pieces to continuous forms allows for high-volume manufacturing. The web-shaped material can be introduced into the layer continuously as it moves through the production line, significantly increasing productivity while maintaining flexibility in production scale through adjustments in web width, speed, and unwinding rate.

AI summary
The invention relates to a method for producing serially interconnected optoelectronic components as well as optoelectronic components interconnected according to the method. In a first step, an electrically non-conductive layer with optoelectronic material introduced therein and at least one first wire or thread (2) located in the layer is produced. The first wire or thread either is electrically conductive from the outset or can subsequently be treated in such a way that it becomes electrically conductive as a result of the treatment. A first and second electrooptically active region of the layer is electrically connected to the first wire or thread in such a way that they are electrically interconnected to each other in series. By the wire, regions of the layer are subdivided in a simple manner, as a result of which a plurality of optoelectronic components are produced in a technically simple manner. Continuous production is possible.
