“…Careful weaving of metallised polymer warp yarns and coated polymer photoanode weft yarns has provided an all-solid DSSC textile that has connections to the aligned weft electrodes to make strings of the small PV cells and yield a 1.3% efficiency [6]. The more traditional liquid-based DSSC was the basis for a woven textile using warp and weft glass fibres with weft-aligned titanium photoanode and counter electrode wires, that were coated with electrode paste and annealed at 480 °C after weaving and then sealed into a pouch for electrolyte containment [7].…”

Solar cells are an option for powering active electronics on textiles, but should be fully integrated to avoid compromising the flexibility and handle of the basic fabric. Photovoltaic (PV) cells conventionally use rigid silicon wafers but there are also thin-film options, although some are sensitive to moisture and oxygen, and others require processing temperatures outside the range of most flexible materials. The coating on textiles is also influenced by the fabric’s texture, elasticity, and surface roughness. The demands of a flexible structure affect the choice of the other parts of PV cells, namely their electrical contacts and any encapsulation layers. The two alternative routes to a textile PV design are—(i) coat the fabric with successive layers needed to make a sandwich device, or (ii) coat individual yarns with these layers and then process them into a fabric, e.g., by weaving.

“…We have previously studied textile-formed electrochemical devices for fabrication of a wearable device from real fabrics using sewing and weaving technologies 28,29 . From the perspective of the textile, this process is fully developed, however, complications arise because electrodes were first formed by coating and sintering before combining into one device, and for a simple and continuous process, the textile for the cell should be fabricated first, then the electrodes deposited 30 .…”

The demand for easy-to-use portable electric devices that are combined with essential items in everyday life, such as apparel, has increased. Hence, significant research has been conducted into the development of wearable technology by fabrication of electronic devices with a textile structure based on fiber or fabric. However, the challenge to develop a fabrication method for wearable devices based on weaving or sewing technology still remains. In this study, we have proposed and fabricated a 3-D textile with two electrodes and one spacer in a single sheet of fabric, utilizing a commercial weaving machine. The two electrodes fulfil the role of electron transfer and the spacer between the electrodes circulates electrons and prevents electrical shorting. Hence, the 3-D textile could be applied to a wide range of electrochemical devices. In addition, it is possible to control the textile structure, size and quantity and change the electrode or spacer materials by replacing the thread. We applied the 3-D textile to dye-sensitized solar cells (DSSCs) which has distinctive advantages such as low manufacturing cost, esthetic appearance for interior or exterior application and high power output under relatively weak light illuminations. The 3-D textile DSSCs were fabricated through a continuous process, from manufacturing to encapsulation, using a non-volatile electrolyte and demonstrated a specific power of 1.7% (1 sun, 1.5 A.M.). The 3-D textile DSSCs were electrically connected in parallel and series by twisting, stainless steel wires, which were used as the weft, and a light-emitting diode lamp was turned on using 3-D textile DSSCs connected in series. This study represents the first stage in the development and application of wearable textile devices.

“…This approach presents a challenge in large area applications to connect a number of crossed, cylindrical yarn solar cells that have been woven into the textiles 22 . Furthermore, the limitation of the bending radius curvature 23–25 , as well as the fibres are tending to break very easily which will lead degrade 26 in cell performance. In addition, when woven into textiles, they are partially shaded which may reduce the power conversion efficiency.…”

Previously, textile dye sensitised solar cells (DSSCs) woven using photovoltaic (PV) yarns have been demonstrated but there are challenges in their implementation arising from the mechanical forces in the weaving process, evaporation of the liquid electrolyte and partially shaded cells area, which all reduce the performance of the cell. To overcome these problems, this paper proposes a novel fabrication process for a monolithic-structured solid-state dye sensitized solar cell (ssDSSC) on textile using all solution based processes. A glass fibre textile substrate was used as the target substrate for the printed ssDSSC that contain multiple layers of electrodes and active materials. The printed ssDSSC on textile have been successfully demonstrated and compared with a reference device made with the same processes on a glass substrate. All PV textile devices were characterized under simulated AM 1.5 conditions and a peak efficiency of 0.4% was achieved. This approach is potentially suitable for the low cost integration of PV devices onto high temperature textiles, but to widen the range of applications future research is required to reduce the processing temperature to enable the device to be fabricated on the standard fabric substrates.
