研究目的
Investigating the integration of photovoltaic cells into textiles to power active electronics without compromising the fabric's flexibility and handle.
研究成果
The study demonstrates the feasibility of integrating photovoltaic cells into textiles, offering a lightweight and flexible solution for powering wearable electronics. However, challenges remain in improving efficiency, ensuring durability, and scaling up production. Future research should focus on optimizing layer deposition techniques and developing more effective sealing methods to enhance performance and longevity.
研究不足
The challenges include reducing the roughness and discontinuity of textile surfaces, ensuring thin conformal layers for high optical absorption without weakening the built-in field, and solving the issue of effective hermetic sealing without compromising flexibility. Large area production of PV’s on textiles also lags behind PV’s on plastic film.
1：Experimental Design and Method Selection:
The study explores two main approaches for integrating PV cells into textiles—coating the fabric with successive layers to make a sandwich device or coating individual yarns with these layers before processing them into a fabric.
2：Sample Selection and Data Sources:
The research utilizes woven polyester fabric as a substrate for PV cells, focusing on its texture, elasticity, and surface roughness.
3：List of Experimental Equipment and Materials:
Includes woven polyester fabric, PEDOT:PSS for smoothing surfaces, aluminium for electrical contacts, and a-Si:H for the photoactive layer.
4：Experimental Procedures and Operational Workflow:
The process involves calendering the polyester surface, applying a PEDOT:PSS layer, followed by aluminium deposition, and then coating with a-Si:H layers via plasma enhanced CVD.
5：Data Analysis Methods:
The performance of the textile-based PV cells is assessed under standard test conditions to evaluate efficiency and flexibility.
