Mimicking the Veins in a Leaf, Scientists Hope to Make Super-Efficient Displays and Solar Cells

InterNano Industry News - March 4, 2017 - 4:45am
<?xml version="1.0" encoding="UTF-8"?> Fractals and biomimetics just helped to surpass the performance of today’s transparent electrode materials Image: M. Giersig/HZB If you take a close look at a leaf from a tree and you’ll notice the veins that run through it. The structure these veins take are what’s called a quasi-fractal hierarchical networks. Fractals are geometric shapes in which each part has the same statistical character of the whole. Fractal science is used to model everything from snowflakes and the veins of leaves to crystal growth. Now an international team of researchers led by Helmholtz-Zentrum Berlin have mimicked leaves’ quasi-fractal structure and used it to create a network of nanowires for solar cells and touch screen displays. Indium tin oxide (ITO) has been the go-to material for transparent conductors in displays and solar cells. While the costs associated with ITO have been one of the main knocks against it, it’s been difficult for the various nanomaterials proposed as alternatives to replace it.  Nanomaterials—including silver nanowires, carbon nanotubes and graphene—have not only been handicapped by their own relative high costs, but their performance has been somewhat lacking as well. With this new method of distribution, nanowires are able to surpass the performance of traditional ITO layers. The reason for this becomes a little clearer when you go back and look at the leaf. The distribution of veins in the leaf is determined in part by the amount of shade and sunlight the leaf receives. With ITO, the material is spread out in one continuous, uniform film. However, the way the sunlight strikes a solar cell or the way a finger presses on a touch-screen display are not uniform. This reduces the ITO layer’s efficiency. In research described in the journal Nature Communications , the international research team used a quasi-fractal hierarchical network to optimize the distribution of the nanowires on a solar cell according to three conditions: provide maximum surface coverage, achieve a uniform current density, and have a minimal overall resistance. “On the basis of our studies, we were able to develop an economical transparent metal electrode," Michael Giersig, a professor at Helmholtz-Zentrum Berlin and who led the research, said in a press release. “We obtain this by integrating two silver networks. One silver network is applied with a broad mesh spacing between the micron-diameter main conductors that serve as the ‘highway’ for electrons transporting electrical current over macroscopic distances.” Next to this broad highway for the electrons, the researchers added randomly distributed nanowire networks that serve as local conductors to cover the surface between the large mesh elements. “These smaller networks act as regional roadways beside the highways to randomize the directions and strengths of the local currents, and also create refraction effects to improve transparency,” according to Giersig. Solar cells with the leaf-vein network had an efficiency of 5.91 percent in experiments. Those with a standard ITO had 5.37 percent.

A transparent flexible thin-film triboelectric nanogenerator for scalable electricity generation

InterNano Industry News - March 4, 2017 - 4:45am
A transparent flexible thin-film triboelectric nanogenerator for scalable electricity generationGuang Zhu; Xiao Yan Wei; Zhong Lin WangInternational Journal of Nanomanufacturing, Vol. 12, No. 3/4 (2016) pp. 396 - 403We report a flexible thin-film-based triboelectric nanogenerator (TF-TENG) that has a one-component laminated structure as thin as 100 µm. The electricity-generating process of the TF-TENG takes advantage of the interaction between the TF-TENG and an external object that carries triboelectric charge on the surface. The motion of the object creates electric potential difference between two electrodes on the TF-TENG, which then produces electron flow in the external circuit. When triggered by foot stomping, a TF-TENG (20 cm by 20 cm) spread on the floor could generate an open-circuit voltage of 700 V, a short-circuit current of 3 mA, and an instantaneous power of 168 mW that corresponds to a power density of 4.2 W/m&lt;SUP align="right"&gt;2&lt;/SUP&gt;. The generated electricity could simultaneously power 1,000 LEDs. The TF-TENG can be tailored to any desired size and shape that are suitable in a variety of circumstances as long as contacts with external objects take place. When the TF-TENG is scaled up in area and used in places that have large flows of people such as subway stations and shopping malls, the produced electric energy in total may become considerable.

International Conference on Nanotechnology, Nanomaterials & Thin Films for Energy Applications

InterNano - Upcoming Events - March 2, 2017 - 2:53pm
ConferenceWednesday, July 26, 2017 to Friday, July 28, 2017Aalto University, Finland http://www.nanoenergy.co.uk/ The potential of nanotechnology for energy related applications is enormous. The use of nanomaterials for energy applications can be addressed at almost any scale, from picowatts to megawatt size. Nanomaterials can address many unmet needs in energy applications; they can be used to improve energy densities, efficiencies, increase rates of energy transfer, and increase stabilities for example. Nanotechnology also has the potential to facilitate hitherto underdeveloped or unknown commercial applications for energy (smart clothing, flexible electronics, covert inks, energy scavenging/converting devices) as well as bring down the cost of new energy technologies and enable their mass production. Within the field of nanotechnology, new materials development will play an important role toward a sustainable energy future. The NANOENERGY conference is an offshoot from the more established NANOSMAT conference. Since 2005, “NANOENERGY” has been organized as a “Symposium” each year at the NANOSMAT conferences. As a result of the growing success of the NanoEnergy symposia held during the NANOSMAT conferences – the first ever standalone “International Conference on Nanotechnology, Nanomaterials & Thin Films for Energy Applications” was held at the University College London (UCL) in London, UK during 19-21 February 2014, which was a huge success and with attendance exceeding 200 plus. The 2nd NANOENERGY conference was held in Manchester, UK during 1-3 June 2015 and the 3rd NANOENERGY was held at the University of Liverpool (UK) in July 2016. The 4th NANOENERGY conference will address the theory, design, research, discovery and development of new materials and nanotechnologies in relation to the field of energy applications (e.g. in energy harvesting, production, storage, transfer and use, etc.). NANOENERGY aims to bring together academia, industries and policy makers interested in the application of nanotechnology in the energy sector. The conference will discuss the state-of-the-art and latest development of nanotechnology, nanomaterialsand thin filmsfor energy applications but also investigate possible avenues ahead. High-level experts both from academia and industry will address key issues relating to the topics of this conference. A wide range of disciplines will be included from theory to experiments, device development, technology demonstration, manufacture and scale-up of nanotechnology applied to energy will be covered.
