Greener electronics

09 May 2013

By Rowan Frame, Development Editor.

Hu and co-workers from the USA and China have advanced us towards flexible electronics that are more recyclable, renewable and inexpensive with findings reported in their recent EES communication.

Biodegradable transparent substrates for ﬂexible organic-light-emitting diodes

The group investigated the fundamental properties of cellulose-based biodegradable, transparent substrates. They found interesting differences in mechanical and optical properties between regenerated cellulose film substrates and cellulose-nanopaper substrates, although both were transparent and suitable for printed electronic devices. This was demonstrated using organic-light-emitting diodes on the substrates.

Flexible devices commonly use plastic substrates, which have limited recyclability and are not produced from sustainable sources. The authors hope that their investigation will allow for the replacement of plastic with more sustainable substrates.

New results challenge understanding of how microbial fuel cells work

01 May 2013

By Heather Montgomery, Deputy Editor.

Parting with ideas previously reported in the literature, Scientists based at Washington State University and the Pacific Northwest National Laboratory in the USA found that the metabolic activity of a Geobacter sulfurreducens biofilm were higher at the surface of the film due to low porosity, with acetate unable to penetrate further in.

They found, however, that long-range electron transfer was not restricted by electrical resistance through the biofilm.

The results could help researchers optimise the conditions needed for maximum microbial fuel cell performance.

Large-scale energy storage – a step forward

29 Apr 2013

By Heather Montgomery, Deputy Editor.

Scientists in the US have developed a new lithium/polysulfide (Li/PS) semi-liquid battery for large-scale energy storage, with lithium polysulfide (Li₂S₈) in ether as a catholyte and metallic lithium as an anode.

As the catholyte is designed to cycle only in the range between sulfur and Li₂S₄ it avoids detrimental effects due to the formation and volume expansion of solid Li₂S₂/Li₂S. This proof-of-concept Li/PS battery can reach 170 W h kg^-1 and 190 W h L^-1 at its solubility limit. It achieved an energy density of 108 W h L^-1 and 97 W h kg^-1 based on the mass of the polysulphide catholyte and lithium.

The cost of raw materials in this system was as low as $45 kW h^-1 and $145 kW^-1. Moreover, no expensive ion-selective membrane is needed for this system.

Reducing the cost of perovskite solar cells: EES article in Chemistry World

24 Apr 2013

By Hannah Porter, Publishing Assistant.

Solar cells are already beginning to enjoy widespread adoption © Shutterstock

A new way of making semiconducting perovskite-based solar cells could result in photovoltaic devices that are 70% cheaper than current commercial models, say UK scientists.

Although dye-sensitised solar cells (DSSCs) have been leading the charge in cheap-to-process cell designs, semiconducting perovskites have been used in recent years to replace the sensitiser in the DSSC architecture. Whilst this reduces the interfacial energy loss that plagues DSSCs, the metal oxide support layers still need to be sintered at 500°C, which is costly.

Continuing their work on a ‘meso-superstructured’ solar cell, where they simplified the design of semiconducting perovskite solar cells, Henry Snaith and his group at the University of Oxford have used colloidal chemistry to deposit a support layer of aluminium(III) oxide. The highest temperature this method needs is a 150°C drying step, which will not only result in cheaper devices, but could also lead to better designs.
