“…Plentz et al explored fiber glass textiles as the flexible substrate, on which they deposited a-Si:H p-i-n junctions using plasma-enhanced chemical vapor deposition (PECVD). 28 The solar cell structure achieved an efficiency of 1.41%, with a fill factor of 0.43, short circuit current density of 3.70 mA cm 2 , and open circuit voltage of 0.88 V. It is not clear whether the individual fiber glass of the textiles is conformally coated with a-Si:H or not from this report, and there lacks literature on using PECVD to deposit materials on fabrics. The HPcCVD, as demonstrated earlier, can conformally coat the individual fibers on the fabrics, providing a new scheme of integrating functional materials into flexible textiles.…”

“…Hybrid Solar Cell Fabrication : The conventional a‐Si:H p + –i–n + ‐doped stack model was employed with highly p‐doped a‐Si:H (10 nm), intrinsic a‐Si:H (300 nm), MPEGC 60 morphologies as the n‐type layer, and the MPEGC 60 layer was replaced with highly n‐doped a‐Si:H (10 nm) for two reference solar cells. Except for the fullerene part, all layers were deposited using plasma enhanced chemical vapor deposition (PECVD) onto a 200 nm Al‐doped ZnO (AZO) layer serving as transparent front contact.…”

It is demonstrated that systematic and designated control of supramolecular nanostructures via interfacial engineering enables (opto)electronic C60‐material properties to be widely adjusted. Interestingly, the lowest unoccupied molecular orbital (LUMO) energies of the same amphiphilic fullerene species are tuned up to 120 meV using supramolecular assembly, competitive to complete molecular change; cf. PC61BM to PC71BM causes a change of 200 meV. Morphology control is achieved through different thin‐film production techniques involving molecular assembly at interfaces, including liquid–liquid interfacial precipitation (LLIP), and Langmuir–Blodgett technique at air–water interface. LLIP enables supramolecularly ordered extended surfaces, yielding the least electronically stable LUMO (ELUMO = −4.28 eV). After qualitatively explaining the observed electrochemical LUMO energy variation for these assemblies with varied molecular packing and aggregate dimensions, an analytical equation is proposed, connecting morphological parameters with LUMO energies with prospects in supramolecular chemistry. To demonstrate the applicability of supramolecular structure–electronic property relations and of supramolecular structure fabrication protocols established in this work to tailor device properties, amorphous‐Si/fullerene hybrid solar cells are built and characterized. It is found that the supramolecular structure variation can be successfully translated to the solar cells, giving rise to a prototype linear relation between LUMO energy and open‐circuit voltage.

“…These are sufficiently conducting and very flexible, although Ag-NW's will have to be protected against atmospheric corrosion if exposed and are sharp enough to penetrate adjacent layers. The roughness of woven textiles has been smoothed out by dip coating in a resin [4], which makes the textile rather stiff or by screen-printing liquid polyimide [5]. Alternatively, doctor blading a PEDOT:PSS layer before metallising provides a smooth surface and also an electrical path past any microcracks in the metal conductor.…”

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.
