Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If thin-film solar cells are used to achieve high transmittance, then visibility is improved, but energy conversion efficiency deteriorates
Solution Approach 1:
The solar cell is divided into multiple thin-film solar cell units arranged in an array, where each unit is optimized for high transmittance while the collective arrangement achieves improved energy conversion efficiency through optimized spacing and configuration
Solution Approach 2:
The patent uses composite structures combining thin-film solar cells with transparent resin layers and glass substrates, creating a multi-layer composite that simultaneously achieves high transmittance and improved energy conversion efficiency through optimized material combinations
2Power
If conventional solar cell materials are used, then energy conversion efficiency is improved, but image distortion worsens due to refractive index mismatches
Solution Approach 1:
The patent employs materials with matched refractive indices throughout the solar cell structure, including the use of transparent resin layers with refractive indices closely matching both the glass substrate and the thin-film solar cells, creating optical homogeneity that eliminates image distortion while maintaining energy conversion efficiency
Solution Approach 2:
Transparent resin layers are introduced as intermediary materials between the glass substrate and thin-film solar cells, acting as optical mediators that match refractive indices to prevent light refraction and image distortion while allowing efficient energy conversion
