1Ease of manufacture
If spin coating process is used to manufacture organic electronic components, then the process is simple and low-cost, but the material usage rate is merely 5% and the yield for manufacturing big-area photoelectric elements is extremely low
Solution Approach 1:
The patent changes the processing parameters by introducing a two-stage heating process with specific temperature ranges (first heating at 60-80°C, second heating at 80-100°C) and controlled heating rates (0.5-2°C/min), which optimizes the formation of multilayer structures and significantly improves manufacturing yield for big-area elements while maintaining process simplicity
Solution Approach 2:
The patent applies preliminary action by pre-heating the substrate to a first temperature range (60-80°C) before applying the second organic material solution, which prepares the substrate surface to receive subsequent layers uniformly and prevents solvent damage to underlying layers, thereby improving overall manufacturing yield
