Photovoltaics with Nanotubes

06.11.2012
Researchers of the University of Würzburg are significantly involved in the new European collaborative project POCAONTAS. They intend to develop novel materials for photovoltaics from carbon nanotubes. The project is funded by the European Union with EUR 3.5 million.
The conversion of solar energy into electrical power plays a major role in the successful transition to renewable energy sources. Although conventional silicon solar cells have come to be highly efficient, their production is expensive and consumes a lot of energy. Therefore, it is certainly worthwhile to look for alternatives.

Properties of the material are promising

For this reason, a new research network is going to determine which materials are suitable for the photovoltaics of the future. Tiny tubes of pure carbon that are arranged into larger structures seem to be excellent candidates: "This material has many properties holding considerable promise for a highly efficient energy conversion," says Professor Tobias Hertel of the University of Würzburg.

The material is interesting for photovoltaics due to its great stability and exceptionally high electron mobility. It also has a light absorption spectrum – not easily attainable by any other materials – that is very suitable for energy conversion.

The researcher's objectives

"Although we have been working in the field of organic photovoltaics for years, our first experiments with the high-grade nanotubes didn't fail to thrill and motivate us," recounts Hertel's Würzburg project partner, Professor Vladimir Dyakonov.

The scientists now intend to further explore the photovoltaic potential of carbon nanotube polymer composites. Special focus is put on the development of socalled functional composite systems. The properties of these systems are to be analyzed with cutting-edge spectroscopic methods.

Training of young researchers important

Apart from the research, the training of doctoral students and postdoctoral researchers in science and industry is an essential objective of the project. On their respective location, the project partners offer courses, industrial internships and workshops in order to provide young researchers with expert knowledge and to prepare them for an academic career.

Project partners and coordination

The project is called POCAONTAS (Polymer-Carbon Nanotubes Active Systems for Photovoltaics). Apart from the Würzburg study groups of Professor Tobias Hertel (chemistry) and Professor Vladimir Dyakonov (physics), it includes further research groups from Munich and five other European countries. Several companies, including two from Bavaria, and the Bavarian Research Alliance have also joined in. The project is coordinated by Professor Larry Lüer (Madrid).

Under the "Initial Training Network" program, the European Union will fund the project with altogether EUR 3.5 million over a period of four years, starting from 1 November 2012. According to Professor Hertel, there is a fierce competition for the funds: "Only very few projects that have been recognized as excellent receive such grants."

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
