Laboratory for Thin Films and Photovoltaics
The Laboratory for Thin Films and Photovoltaics is involved in the research and development of high efficiency thin film solar cells with emphasis on novel concepts for enhancing the performance of solar cells, simplifying the fabrication processes, and advancing device structures for next generation of more efficient and low cost devices not only for terrestrial but also for space applications. The technologies investigated include both CdTe and CuIn1-xGaxSe2, which are promising compounds for cost reduction in solar electricity generation compared to classical crystalline silicon cells.

Flexible CIGS Solar Cell
Development of high efficiency, stable, lightweight and flexible solar cell is important for terrestrial and space applications. We have developed a novel low temperature deposition process to produce solar cells on flexible polymer films. The total thickness of the solar cell including polymer substrate is less than 25 micron. A world record efficiency of 18.7% has been independently certified in 2011. More...
Tandem Cells – Advanced Device Structures for Better Utilization of the Solar Spectrum
18.8% efficient CIGS cells have been developed on glass. However, tandem Cells, i.e., multiple solar cells with different band gaps stacked on top of each other, can increase the total conversion efficiency due to a better utilization of the complete solar spectrum in stacked solar cells of different bandgaps.

Flexible CdTe Solar Cell

CdTe is one of the most promising technologies for industrial production of thin film PV modules. Solar Cells with efficiencies of up to 15.6% were produced in our lab. More...

Functional Inorganic Materials

The newly formed Funtional Inorganic Materials Group (Prof. Maksym Kovalenko) aims to link basic and applied research in the areas of synthesis, self-organization and applications of inorganic functional materials, with specific focus on colloidal nanostructures. To enhance such interdisciplinary scientific program, the research activities are carried out at two institutions within the ETH Domain: EMPA and ETH Zurich.

 

Central to our efforts is the synthesis of inorganic nanocrystals ("NCs"), and the integration and/or self-assembly of NCs into multifunctional solid state structures. Through the proper design and characterization of NC surface chemistry and inter-NC medium, we aim to transform the individual properties of NCs into useful collective properties of NC-based solids. Synthetic work and rigorous materials characterization are the cornerstones of our research. Collectively, these experimental efforts should ultimately provide us with general, cost-efficient, and high-throughput routes to solid-state nanostructured materials for applications in energy conversion and storage.
