AbstractCIGS (Cu(In,Ga)Se2) thin-film solar modules on glass substrates are currently on the verge of commercialization. Entirely new application areas could be accessed with CIGS modules fabricated on thin and flexible non-glass substrates. Additionally, the roll-to-roll manufacturing of such flexible CIGS modules promises to be a low-cost production method. Different external Na supply methods and a vacuum-deposited buffer were investigated in this contribution, a sample of the challenges we face when modifying the standard, industrial CIGS module production process to the particular requirements of flexible substrates. Both metal foil substrates and polymer films are considered. Our excellent best results of above 14 % for single cells on titanium, more than 11% on polyimide, and around 7 % for modules on both substrates indicate our progress in developing flexible CIGS.

AbstractThe development of a low cost roll-to-roll production process for CIGS remains an attractive goal. In the present approach, the absorber is prepared by electrodeposition techniques, while molybdenum, copper or stainless steel (SS) are used as flexible substrates. Two electrodeposition routes are evaluated: sequential plating of Cu, In and Ga followed by Se evaporation is compared to simultaneous (= ternary) electrodeposition of Cu, In and Se. Ternary electrodeposition yields 7.5 % efficiency on stainless steel. The sequential process leads to 9.0 % cell efficiency on copper and on stainless steel substrates.

Printing Processes

Recently low cost production is vital to produce printed electronics by roll to roll manufacturing printing process like a flexographic. Flexographic has a high speed technique which commonly used for printing onto large area flexible substrates. However, the minimum feature sizes achieved with roll to roll printing processes, such as flexographic is in the range of fifty microns. The main contribution of this limitation is photopolymer flexographic plate unable to be produced finer micron range due to film that made by Laser Ablation Mask (LAMs) technology not sufficiently robust and consequently at micron ranges line will not be formed on the printing plate. Hence, polydimethylsiloxane (PDMS) is used instead of photopolymer. Printing trial had been conducted and multiple solid lines successfully printed for below fifty microns line width with no interference between two adjacent lines of the printed images.

Abstract Mesoporous silica (referred to as MPS), which has pores of hexagonal or cubic structure of several nm to several tens of nm on the surface, is attracting attention as a new material. MPS has a very large specific surface area, so it is used as an adsorbent for gas and water vapor, as a moisture absorbent, and as a separating material. Transparent MPS is also expected to be an optical functional material. MPS thin film is expected to be used as a thin film as an application example. Since MPS thin film can be used in various applications, it will be further developed by mass production. Leads to Therefore, in this study, mass production of MPS thin films and controlled the film thickness was studied. Roll-to-roll (referred to as R2R) production method and a micro gravure printing method was adopted as a method of mass production: transporting polypropylene film and coating on it. As a result, the MPS thin film prepared in this study had a pore structure. it was confirmed that the film thickness could be controlled by changing the peripheral speed ratio. It is considered that the size of the liquid pool between the coating rolls changed. The size and arrangement of the pores could be confirmed by FE-SEM observation.

ABSTRACTInverters made of monolithically integrated p- and n-channel thin film transistors of nanocrystalline silicon were demonstrated on both Corning 1737 glass and Kapton E polyimide substrates. The TFT's geometry is staggered top-gate, bottom-source/rain. A nc-Si:H seed layer promotes the structural evolution of the nc-Si:H channel. Electron field-effect mobilities of 15 - 30 cm2V−1s-1 and hole mobilities of 0.15 - 0.35 cm2V−1s−1 were obtained. Slightly lower carrier mobilities were observed in the TFTs made on polyimide than on glass substrates. High gate leakage currents and offsets between the supply HIGH voltages and the output voltages in the inverters indicate that the low-temperature gate dielectric needs improvement.

AbstractOrganic photovoltaic (OPVs) devices are promising due to their low cost, light weight, and compatibility with high throughput processing on flexible substrates. This paper demonstrates a simple process utilizing thin-film instabilities to enhance light absorption in OPVs in a way that is compatible with planar processing and the customary thermal annealing steps. Placing a thin, transparent polystyrene (PS) film between the glass substrate and the transparent conductive indium tin oxide (ITO) electrode results in the formation of periodic surface buckles in the PS layer due to induced strain caused by thermal expansion mismatch between the ITO and PS films. OPVs comprising bilayer laminates of copper phthalocyanine (CuPc) and fullerene (C

Titanium dioxide (TiO2) is coated onto the materials (e.g.glass ceramic) to inhibit the bacteria growth. TiO2has become a popular photocatalyst for both air and water purification. It has also shown to be very active for bacterial destruction even under UV light. The photocatalytic of TiO2involves the light-induced catalysis of reducing and oxidizing reactions on the surface of materials. The spray pyrolysis technique for material synthesis in thin-film configuration is an interesting option due to the use of inexpensive precursor materials and low-cost equipment suitable for large-area coatings. In this research, TiO2thin films were deposited onto glass substrates using spray pyrolysis technique. Escherichia coli (E.coli) was used as testing bacteria. TiO2thin films showed some antibacterial effect in the halo test.
