Solution Overview
Problem
Conventional solar cell modules lack sufficient design aesthetics and face challenges in power generation efficiency when installed on walls due to excessive sunlight blocking by printed materials.
Innovation Solution
A solar cell module with a printed material comprising a light transmissive base material and pattern printed layers, including first and second color pattern layers with interference pigments that generate different interference lights, and optionally a transmissive smoke-printed layer, to express a three-dimensional pattern while ensuring sunlight transmissivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional printed materials are used on solar cell modules, then design aesthetics are improved, but power generation efficiency deteriorates due to excessive sunlight blocking
Solution Approach 1:
The patent applies interference pigments that create iridescent color effects through light interference rather than traditional pigments that absorb light. This allows the printed material to display vibrant, three-dimensional patterns while maintaining high light transmissivity for solar cell power generation.
Solution Approach 2:
The patent uses composite printed materials combining light transmissive base materials with interference pigment layers. This composite structure achieves both aesthetic patterning and functional light transmission for maintaining power generation efficiency.
2Shape
If multiple color layers are added to enhance design aesthetics, then color matching complexity increases
Solution Approach 1:
The interference pigments naturally produce multiple colors through light interference effects when viewed from different angles, eliminating the need for multiple separate color printing layers and their associated alignment complexities.
Solution Approach 2:
The patent transitions from traditional planar color printing to three-dimensional interference patterns that create depth and color variation through the vertical structure of the pigment layers, adding a dimensional aspect that simplifies color matching.
