研究目的
To develop and optimise a method to obtain reproducible photovoltaic textiles using a fully spray coating processing at low temperature on a standard 65/35 polyester cotton fabric.
研究成果
Fully spray-coated fabric solar cells on standard polyester cotton fabrics have been demonstrated with a PCE of 0.02%. The approach is suitable for the low-cost integration of PV devices into clothing and other decorative textiles, offering potential for wearable energy harvesting applications.
研究不足
The main challenge is the surface roughness of the polyester cotton fabric, which affects the uniformity and performance of the spray-coated layers. The efficiency of fabric-based solar cells is significantly lower than that of glass-based counterparts.
1：Experimental Design and Method Selection:
The study involves using spray coating to fabricate organic solar cells on fabrics. The process includes screen printing an interface layer to smooth the fabric surface, followed by spray-coating functional layers including AgNW electrodes, ZnO-NP electron transport layer, P3HT:ICBA photoactive layer, and PEDOT:PSS hole transport layer.
2：Sample Selection and Data Sources:
Standard 65/35 polyester cotton fabric was used as the substrate.
3：List of Experimental Equipment and Materials:
Materials include polyurethane based interface paste, AgNW suspension, ZnO-NP dispersion, PEDOT:PSS dispersion, and P3HT:ICBA blend. Equipment includes a screen printer, spray coater, ABET solar simulator, and SEM.
4：Experimental Procedures and Operational Workflow:
The fabric was screen printed with an interface layer, followed by spray-coating of functional layers in a nitrogen atmosphere glovebox. The devices were characterized under AM
5：5 irradiation. Data Analysis Methods:
The performance of the solar cells was evaluated using J/V measurements, and device morphologies were examined by SEM.
