Profile
EMPA (Swiss Federal Laboratories for Material Testing and Research)is an interdisciplinary research and services institution to meet the requirements of industry and the needs of our society, and it links together applications-oriented research and the practical implementation of new ideas. The Laboratory for Thin Films and Photovoltaics has recently relocated from ETH Zurich. Dr. Ayodhya N. Tiwari has been leading the PV group involved in the R&D of thin film solar cells based on compound semiconductors. The group has made several important contributions in the field of CIGS and CdTe thin film solar cells on glass and flexible substrates including the achievement of 14.1% efficiency (highest efficiency record for any type of solar cell grown on polymer film) flexible CIGS solar cell on polymide film and 11.4% record high efficiency for flexible CdTe solar cells. Other innovative developments include flexible CIGS solar cells on low cost aluminium foil, application of simple and safe non-vacuum CIGS deposition processes, high efficiency multi-junction (tandem) solar cells based on CIGS, CdTe, and Dye sensitized solar cells. The lab is involved in collaborative and industrial research, and technology transfer to start-up companies.

3D Printing Drones Build and Repair Structures While Flying

3D printing is gaining momentum in the construction industry. Both on-site and in the factory, static and mobile robots print materials for use in construction projects, such as steel and concrete structures. This new approach to 3D printing uses drones, that use collective building methods inspired by natural builders like bees and wasps who work together to create large, intricate structures.

A Water Activated Disposable Paper Battery

A team of researchers have developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics - such as smart labels for tracking objects, environmental sensors and medical diagnostic devices - and minimize their environmental impact.

Smart Bandage Releases Medication as Soon as Infection Starts

A bandage that releases medication as soon as an infection starts in a wound could treat injuries more efficiently. Researchers are currently working on polymer fibers that soften as soon as the environment heats up due to an infection, thereby releasing antimicrobial drugs.

Shellac for Printed Circuits

More precise, faster, cheaper: Researchers all over the world have been working for years on producing electrical circuits using additive processes such as robotic 3-printing (so-called robocasting) - with great success, but this is now becoming a problem. The metal particles that make such "inks" electrically conductive are exacerbating the problem of electronic waste.

Energy Harvesting Wooden Floors

Researchers from Switzerland are tapping into an unexpected energy source right under our feet: wooden floorings. Their nanogenerator enables wood to generate energy from our footfalls. They also improved the wood used in the their nanogenerator with a combination of a silicone coating and embedded nanocrystals, resulting in a device that was 80 times more efficient—enough to power LED lightbulbs and small electronics.

The Biodegradable Battery

The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.

Invisible "Keyhole" Made of Printed, Transparent Electronics

What initially looks like a simple transparent film conceals a whole new level of security. Invisible buttons are printed with conductive ink on the transparent carrier material, the position of which is known only to insiders. Such circuits can be connected to a door lock as an access code, for instance. If the buttons on the polymer film are pressed in the correct order, the door opens.

Energy Harvesting Smart Floors

Researchers have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring wood-degrading fungi take over the task of modifying the wood.

Turning Streetwear Into Solar Power Plants

Researchers have succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly where it is needed, i.e. in the use of everyday electronics.
