    Perovskite solar cells: perfection not required!

    Experiments at BESSY II reveal why even inhomogeneous perovskite films are highly functional 

    Metal-organic perovskite layers for solar cells are frequently fabricated using the spin coating technique. If you follow the simplest synthesis pathway and use industry-relevant compact substrates, the perovskite layers laid down by spin coating generally exhibit numerous holes, yet attain astonishingly high levels of efficiency. The reason that these holes do not lead to significant short circuits between the front and back contact and thus high-rate charge carrier recombination has now been discovered by a HZB team headed by Dr.-Ing. Marcus Bär in cooperation with the group headed by Prof. Henry Snaith (Oxford Univ.) at BESSY II.

    Milestone reached: electron source for bERLinPro produces its first beam

    On the HZB Adlershof campus, researchers are building a prototype of an energy-recovery linear accelerator (bERLinPro). Intensive research has been going on for years to develop the worldwide unique key components required for this accelerator. Now, the scientists and engineers have reached a very important milestone: from the interactions between cathode, laser pulse and electric field inside the cavity, the first electrons have been produced and accelerated.
