Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in manufacturing organic or organic-inorganic hybrid electronic devices is the difficulty in achieving mass production due to the requirement for vacuum deposition at normal pressure, which is not feasible with the roll-to-roll process, leading to high costs and performance issues.
Innovation Solution
A method involving the preparation of laminates with buffer layers and a carbon electrode, allowing for the attachment of these layers at normal pressure, reducing contact resistance and enabling the use of inexpensive coating and lamination processes to form electrodes, facilitating a roll-to-roll continuous process.

1Reliability
If vacuum deposition is used to apply the upper electrode, then the performance of the device is secured, but mass production becomes difficult because vacuum deposition cannot be performed at normal pressure
Solution Approach 1:
The invention changes the pressure parameter from vacuum to normal pressure by replacing vacuum deposition with solution-based coating methods. This allows the electrode application process to be performed under normal atmospheric conditions, enabling roll-to-roll continuous manufacturing while maintaining device performance through careful control of solution composition and coating parameters
Solution Approach 2:
The invention substitutes the mechanical vacuum deposition system with a chemical solution-based coating system. Instead of using vacuum equipment to deposit electrodes, the patent employs solution processing methods such as spin coating, dip coating, or slot-die coating that can operate at normal pressure, thereby enabling continuous manufacturing processes
2Reliability
If vacuum deposition is used to apply the upper electrode, then electrode performance is secured, but process cost increases and roll-to-roll continuous process cannot be applied
Solution Approach 1:
The invention replaces expensive vacuum deposition equipment and materials with inexpensive solution-based coating materials and equipment. The use of solution-processable electrodes allows for low-cost manufacturing using simple coating apparatus that can be integrated into roll-to-roll production lines, dramatically reducing process costs while maintaining adequate electrode performance
Solution Approach 2:
The invention changes the processing conditions from vacuum-based physical deposition to normal pressure chemical coating. This parameter change enables the use of cost-effective solution processing methods and simple equipment, making the manufacturing process more economical and suitable for continuous production while preserving electrode functionality
