Spicing up solar power

The photomontage shows how the Fraunhofer IAO building in Stuttgart could be fitted with an “efficient design” solar façade. Image copyright Fraunhofer IOF.

With the help of thin-film technologies, researchers have now been able to turn solar cells into colorful creations.

Imaging material defects in thin film solar cells

Experimental setup used to map defect densities in organic thin films. A pulsed laser beam is used to raster-scan the material of interest, which is assembled in a field-effect geometry, allowing changes in current flow to be detected. The yellow zones indicate sites at which the defect density is particularly high. Christian Westermeier.

A team has, for the first time, succeeded in functionally characterizing the active layer in organic thin-film solar cells using laser light.

A step towards QD solar cells

This illustration shows a lead sulfide quantum dot array. Each quantum dot (the colored clusters) is 'passivated' by molecules that bind to its surface. Dots that are made up of unequal amounts of lead and sulfur tend to cause electrons (shown in red) to become highly localized, which can substantially lower the electrical transport of the device. Image: Donghun Kim and Jeffrey C. Grossman.

MIT researchers find that the secret lies in off-kilter ratios of the two basic components that make up the dots.
