Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar cell modules based on Glass-Ethylene Vinyl Acetate (EVA) are inflexible and difficult to install on curved structures, and the related art flexible solar cells face durability issues and require specific connection structures based on installation environments.
Innovation Solution
A solar cell with an assembled tessellation structure where unit cells are formed in flat polygonal plates with groove-like electrode seats, allowing electrodes to be fitted like Lego blocks, forming a serpentine shape and enabling flexible plane installation, color customization, and adaptable connection circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a laminating process using conductive flexible substrate and film printed with electrode circuit is applied to create flexible solar cell, then the solar cell module can be disposed on curved structure, but durability is low because unit cells are stacked
Solution Approach 1:
The solar cell module is divided into multiple unit cells that can be independently manufactured and then assembled together. Each unit cell is a complete functional element with its own electrodes, allowing modular assembly that maintains structural integrity while enabling flexible installation configurations including curved surfaces.
2Reliability
If electrode circuit is designed in serial and parallel connection structure with thicker connection parts, then connection is achieved, but manufacturing type must be differently applied according to installation environment
Solution Approach 1:
The unit cells are designed with standardized electrode connection structures that can universally accommodate both series and parallel connection configurations. The electrode seats and connection parts are formulated to work with either connection type without requiring different manufacturing processes, allowing the same unit cell design to be used across various installation environments and circuit requirements.

AI summary
Proposed is a solar cell having an assembled tessellation structure, in more detail, a solar cell having an assembled tessellation structure that can be installed on various shapes of installation surface including a curved surface. The solar cell includes unit cells each formed in a flat polygonal plate shape and each having an electrode seat that is a groove formed on a rear surface thereof toward a side from a center of the flat plate, and electrodes each fitted in all of the electrode seats formed on two unit cells when the two unit cells are sequentially disposed to be in contact with each other on sides, wherein the unit cells and the electrodes are sequentially assembled through fitting like Lego blocks.
