研究目的
To develop a fabrication method for dye-sensitized solar cells (DSSCs) on woven polyester cotton fabric for wearable energy harvesting applications.
研究成果
Screen printed DSSCs on Kapton and fabrics have been fabricated and achieved PCEs of 7.03% and 2.78%, respectively. Future research is needed to overcome the interface deformation to increase and optimise the PCE of fabric based DSSCs.
研究不足
The interface coated fabric based devices suffer from interface deformation after printing the functional layer on top during the annealing stage.
1:Experimental Design and Method Selection:
The study focuses on developing a low-temperature processed TiO2 paste for screen printing and spray coating to fabricate photovoltaic textiles.
2:Sample Selection and Data Sources:
Uses polyimide film (Kapton) and standard woven 65/35 polyester cotton fabrics as substrates.
3:List of Experimental Equipment and Materials:
Includes screen printable polyurethane based interface paste, Dupont 5000 screen printable conductive silver paste, Titanium oxide (TiO2) nanoparticles, and other materials for DSSCs fabrication.
4:Experimental Procedures and Operational Workflow:
Describes the screen printing process, curing, and assembly of DSSCs.
5:Data Analysis Methods:
Photocurrent and voltage measurements were performed using a Keithley 2400 source meter under an ABET 1 Sun Simulator.
