Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semiconductor materials such as silicon and germanium are used to manufacture perovskite material bypass diodes through thin film deposition and photolithography, then the PN junction structure can be formed, but the manufacturing process becomes complicated and requires high-temperature, high-vacuum deposition devices
Solution Approach 1:
The patent changes the manufacturing parameters from high-temperature, high-vacuum deposition to low-temperature solution processing. Specifically, it uses solution-based methods at temperatures below 100°C to form the PN junction structure, eliminating the need for complex thin film deposition and photolithography equipment while maintaining the functional integrity of the bypass diode
Solution Approach 2:
The patent replaces mechanical/physical vapor deposition systems with chemical solution-based processing. Instead of using vacuum deposition devices and photolithography equipment, the invention employs solution casting and chemical treatment methods to form the perovskite layer and PN junction structure, significantly simplifying the manufacturing system
2Reliability
If semiconductor materials such as silicon and germanium are used to manufacture perovskite material bypass diodes through thin film deposition and photolithography, then the PN junction structure can be formed, but the manufacturing cost increases
Solution Approach 1:
The patent employs low-cost, readily available materials and processes for manufacturing the bypass diode. It uses solution-based perovskite materials that can be processed at low temperatures with simple equipment, eliminating the need for expensive vacuum deposition systems and reducing overall manufacturing costs while maintaining functional performance
Solution Approach 2:
The patent changes the processing temperature parameter from high-temperature deposition (typically >500°C for silicon) to low-temperature solution processing (<100°C for perovskite), which reduces energy consumption and allows for simpler, less expensive equipment, thereby lowering manufacturing costs
3Manufacturing precision
If photolithography processes are used in the manufacturing of perovskite material bypass diodes, then precise patterning can be achieved, but the process requirements become extremely high and the manufacturing difficulty increases
Solution Approach 1:
The patent extracts and removes the photolithography step from the manufacturing process. Instead of using photolithography for patterning, the invention employs direct solution-based deposition and self-organizing properties of perovskite materials to achieve the desired pattern structure, eliminating the need for complex photolithography equipment and process control
Solution Approach 2:
The patent utilizes the self-organizing and self-assembling properties of perovskite materials in solution to automatically form the desired pattern and crystal structure. The materials self-organize during low-temperature processing to create the functional bypass diode structure without requiring external patterning guidance from photolithography
