“…For example, stainless steel sheet and mesh, and titanium sheet and mesh have been used as the substrates of DSSCs and reached 7.41% efficiency. [12][13][14][15][16][17][18][19][20] Although the I 3 À /I À electrolyte facilitates the high conversion efficiency in DSSCs, the I 3 À /I À electrolyte is easy to volatilize, and is corrosive to the electrodes and sealing materials, which permit the leakage of electrolyte and instability of the whole cell. Other electrolytes, such as solid state and quasi-solid state electrolyte, ionic liquid and iodide-free electrolyte, have been used to replace the I 3 À /I À electrolyte, but their cell efficiency is not comparable to the latter.…”

A high-efficiency dye-sensitized solar cell prototype has been designed and fabricated, in which the working electrode and counter electrode are in direct contact and singly twisted. The cell is sealed in a capillary. In this solar cell configuration, the area ratio between the counter and working electrode is extremely low which allows the independent adjustment of electrolyte volume and the distance between counter electrode and photo-anode. Also it is more easily sealed compared to planar solar cell. The effects of TiO(2) film thickness, twisted pitch of counter electrode and length of device have been investigated. Our results indicate that this novel configuration has demonstrated excellent modularization function, three dimensional light harvesting capacities and the relative independence of incident light angles due to the symmetry structure. The power conversion efficiency of one cell of 9.5 cm in length can reach up to 5.41% at standard test condition (100 mW cm(-2)) and the power output may double under intense diffuse illumination. As far as we know, this is the longest and most efficient fiber-shaped dye-sensitized solar cell consisting of liquid electrolyte. The longer the fiber-shaped solar cell is, the more suitable it is for woven solar power textile if it is encapsulated in transparent flexible plastic capillary.

“…In the absence of current collector, efficiency was extremely low (0.7%), although in our case metal mesh itself functions as a current‐collecting grid, which was faced opposite to the direction of light irradiation. We would like to emphasize that other research groups have also attempted the fabrication of cylindrical DSSC, but efficiency was always lower as compared with that of the standard flat DSSCs. At the same time, discussion has neither been made regarding the reason behind it nor the report of incident photon‐to‐current efficiency (IPCE) spectra.…”

A cylindrical transparent conductive oxide‐less dye‐sensitized solar cell (DSSC) consisting of glass tube/stainless steel mesh–TiO2–dye/gel electrolytes/Pt‐Ti rod having capability of self‐light trapping is reported. Replacing the glass tube with heat‐shrinkable tube to reduce electrolyte gap and optical loss due to light transmission and reflection led to the enhancement in the power conversion efficiency from 2.61% to 3.91%. Profiling of the current distribution measured by laser beam‐induced current exhibited nearly the same current in the axial and radial directions, suggesting that light reflection on a cylindrical DSSC does not affect the efficiency seriously. Optimized best DSSC in this novel device architecture gave a short‐circuit current density of 11.94 mA/cm2, an open‐circuit voltage of 0.71 V and a fill factor of 0.66 leading to the power conversion efficiency of 5.58% at AM 1.5 under simulated solar irradiation.

14Flexible fiber/wire-shaped solar cells are kind of photovoltaic cells fabricated on 15 wire-like substrates. Fiber-type devices, including inorganic, organic, dye-sensitized 16 and perovskite solar cells, have made great progress in the recent years. Especially, 17 the energy conversion efficiency of fiber dye-sensitized solar cells has increased from 18 < 0.5% to > 9%. In this review, we provided very detailed insights into the 19 development of various fiber/wire-shaped solar cells, conventional materials, and 20 innovative designs. Particularly, we focused on the properties of fiber dye-sensitized 21 solar cells, the innovations for solar energy harvesting, and the integrated power 22 2 systems for electrochemical energy conversion and storage. Although recent studies 1 only provided the initial ideas, flexible fiber/wire-shaped solar cells facilitated the 2 breakthrough for novel solar architecture and portable/wearable electronics or 3 e-textiles of the future.4 Keywords: fiber/wire shaped solar cells; integrated power systems; energy 5 conversion and storage; portable/wearable electronics 6 7 18 typical solar cells is the planar shape with dimensional extension. Thus, the 19 development of one-or three-dimensional (1D or 3D) photovoltaic cells will break 20 through the limitations of conventional thinking and generate a new concept for solar 21 energy conversion. This vision could also create opportunities for material 22 3 science/structure design that would be interesting as technical innovations and 1 beneficial for special energy applications. 2 With the rapid development of traditional industry and increasing demand of 3 modern electronics, the integrated optoelectronic products come to the age of small, 4 portable, lightweight and smart merchandise. In recent years, wearable/portable 5 electronics, such as Google glasses, iWatch, and smart phone, have gradually become 6 part of human lives. To deepen the wearable concept and meet future individual needs, 7 incorporating flexible optoelectronic devices (e.g., sensors, logic circuits, antenna, 8 lighting elements, and power systems) in clothing, backpacks, and other belongings 9 would become an important trend for the next generation of smart products, namely 10 "electronic textiles" or "e-textiles" 4, 5 . The fundamental functional units for e-textiles 11 remain to be developed. Especially, flexible power sources with efficient energy 12 conversion and storage can automatically generate electricity and contribute to 13 self-driven energy systems 6-8 , which are very promising candidates for the 14 portable/wearable electronics that can further enrich e-textiles 9-11 . Among the energy 15 technology innovations, flexible fiber/wire-shaped energy devices, including solar 16 cells, batteries, supercapacitors, light-emitting diodes, and field-effect transistors, are 17 booming in recent years and attracting increasing attention 12-18 . Flexible 18 fiber/wire-shaped energy devices fabricated on fiber-or wire-type conductive 19 substrates are the suitable ...
