Solution Overview

Problem

The manufacture of dye-sensitized solar cells is hindered by the difficulty in eliminating or reducing the use of expensive materials like platinum and ruthenium, necessitating the development of a flexible solar panel that can incorporate alternative, cost-effective components.

Innovation Solution

A flexible solar panel is created using a polymer matrix incorporating a plant extract, specifically an extract of chard (B. vulgaris subsp. cicla), which includes chloroplasts and can be formed with poly(vinyl alcohol) or polystyrene, allowing for the production of a cost-effective and efficient solar panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional dye-sensitized solar cell materials (platinum, ruthenium) are used, then high efficiency is achieved, but manufacturing cost increases significantly

Engineering Contradiction:
ImproveefficiencyVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive, rare materials (platinum, ruthenium) with inexpensive, readily available plant extracts containing chloroplasts. This substitution dramatically reduces manufacturing costs while maintaining functional performance, directly resolving the contradiction between efficiency and manufacturing cost.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention uses plant extracts as a natural copy or alternative to synthetic dyes and noble metal catalysts. The chloroplasts in plant extracts replicate the light-absorbing and catalytic functions of traditional materials, providing a cost-effective substitute that maintains efficiency.

Inventive Principle:
Principle #26Copying

2Stability of the object's composition

If rigid structures are used in solar panels, then structural stability is improved, but flexibility and adaptability are reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidflexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs a flexible polymer matrix to encapsulate the plant extract, creating a thin-film solar panel structure. This flexible substrate allows the solar panel to be bent, folded, and adapted to various surfaces while maintaining structural integrity and functional performance, resolving the contradiction between stability and flexibility.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The invention creates a composite material system combining plant extracts with polymer matrices. This composite structure integrates the light-absorbing properties of chloroplasts with the mechanical flexibility and structural stability of polymers, simultaneously achieving both structural stability and flexibility.

Inventive Principle:
Principle #40Composite materials

AI summary

The flexible dye-sensitized solar panel with an organic chromophore is formed from an organic chromophore dye in a polymer matrix. The organic chromophore dye is extracted from chard (B. vulgaris subsp. cicla). The polymer matrix may be formed from either poly(vinyl alcohol) or polystyrene. The flexible dye-sensitized solar panel with an organic chromophore is made by preparing a solution of the selected polymer in the dye extracted from the B. vulgaris subsp. cicla. The solution is coated on a glass plate and dried to form a thin film. The thin flexible film is removed from the plate, forming the flexible dye-sensitized solar panel with an organic chromophore.
