Antennas for more Efficiency

Nanoantennas of the Highest Precision

In the future, tiny antennas made of metal with the ability to capture sunlight might lead to more efficient photovoltaic power generation. Physicists of the University of Würzburg have now produced such antennas from gold – with a previously unheard of precision. Nanoantennas can collect light and concentrate it into tiny spaces – similarly to a burning lens, but much more efficiently. This allows a more efficient utilization of light energy. more...

One Wavelength Fits All

Structuring of Thin-film Solar Cells with a Single Laser Wavelength

Structuring of a PV module into a number of cells is necessary to lower the current and to increase the voltage, and is typically accomplished with nanosecond laser pulses of different wavelengths. Due to the many available laser sources, complex and expensive scribing setups are necessary. To overcome this a concept for laser structuring of thin-film PV modules using a single wavelength allows prediction of the ablation behaviour for a given laser pulse energy. more...
