Patented nanostructure for solar cells

Rough optics, smooth surface:

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof.…

Insight into loss processes in perovskite solar cells enables efficiency improvements

In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. :

In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the Helmholtz-Zentrum Berlin (HZB) were…
