“…The device performance was improved when multiple spray passes were used; however, the performance was still low compared to the evaporated silver electrodes. Other materials such as PEDOT:PSS, carbon nanotubes and graphene have the potential to be used for electrodes as well [27]. Single-walled carbon nanotube films [28] and silver nanowires [29] have been fabricated by spray coating.…”

Abstract:The capability to fabricate photovoltaic (PV) solar cells on a large scale and at a competitive price is a milestone waiting to be achieved. Currently, such a fabrication method is lacking because the effective methods are either difficult to scale up or expensive due to the necessity for fabrication in a vacuum environment. Nevertheless, for a class of thin film solar cells, in which the solar cell materials can be processed in a solution, up scalable and vacuum-free fabrication techniques can be envisioned. In this context, all or some layers of polymer, dye-sensitized, quantum dot, and copper indium gallium selenide thin film solar cells illustrate some examples that may be processed in solution. The solution-processed materials may be transferred to the substrate by atomizing the solution and carrying the spray droplets to the substrate, a process that will form a thin film after evaporation of the solvent. Spray coating is performed at atmospheric pressure using low cost equipment with a roll-to-roll process capability, making it an attractive fabrication technique, provided that fairly uniform layers with high charge carrier separation and transport capability can be made. In this paper, the feasibility, the recent advances and challenges of fabricating spray-on thin film solar cells, the dynamics of spray and droplet impaction on the substrate, the photo-induced electron transfer in spray-on solar cells, the challenges on characterization and simulation, and the commercialization status of spray-on solar cells are discussed.

“…Apart from the processing of ITO, the material involves the very rare metal indium and possesses some less critical attributes such as brittleness and poor thermomechanical properties. There has been a significant research effort aimed at replacing ITO, and while there have been some successful laboratory reports [8][9][10][11][12] only few are directly compatible with large scale processing of Department of Energy Conversion and Storage, Technical University of Denmark, Frederiksborgvej 399, DK-4000 Roskilde, Denmark.

Here we show polymer solar cells manufactured using only printing and coating of abundant materials directly on flexible plastic substrates or barrier foil using only roll-to-roll methods. Central to the development is a particular roll-to-roll compatible post-processing step that converts the pristine and non-functional multilayercoated stack into a functional solar cell through formation of a charge selective interface, in situ, following a short electrical pulse with a high current density. After the fast post-processing step the device stack becomes active and all devices are functional with a technical yield and consistency that is compelling.

“…그러나, OLED의 양극으로 가장 널리 사용되는 ITO(indium tin oxide)는 재료 자체의 취성이 있어 유연한 소자에 적용할 수 없으며, 인듐이 라는 희귀 금속을 사용하기 때문에 값이 비싸다는 문제점이 존재한 다 [2] .이에 따라 ITO를 대체하고자 하는 요구가 점점 증대되고 있 으며, 이러한 노력의 일환으로 탄소나노튜브(carbon nano-tubes), 그래핀(graphene) [3] , 금속나노와이어(metallic nano-wires) [4] 그 리고 전도성 고분자 [5] 등의 투명전극이 집중적으로 연구되어왔다.…”

Article history:This paper reports solution-processed, high-efficiency organic light-emitting diodes (OLEDs) fabricated by a knife coating method under ambient air conditions. In addition, indium tin oxide (ITO), traditionally used as the anode, was substituted by optimizing the conductivity enhancement treatment of poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) films on a polyethylene terephthalate (PET) substrate. The transmittance and sheet resistance of the optimized PEDOT:PSS anode were 83.4% and 27.8 Ω/sq., respectively. The root mean square surface roughness of the PEDOT:PSS anode, measured by atomic force microscopy, was only 2.95 nm. The optimized OLED device showed a maximum current efficiency and maximum luminous density of 5.44 cd/A and 8,356 cd/m 2 , respectively. As a result, the OLEDs created using the PEDOT:PSS anode possessed highly comparable characteristics to those created using ITO anodes.
