There is no doubt: the immediate future of photovoltaics will be decided by materials from the perovskite group. An improved version of a perovskite, containing in the crystal structure a relatively large organic ion, a guanidinium cation, has been developed by chemists from the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Chemistry of Warsaw University of Technology. Laboratory tests at the École Polytechnique Fédérale de Lausanne have shown that photovoltaic cells made of the new perovskite work more efficiently than the cells prepared using its original form.
Tornadoes that carried people and animals into the air were recorded in Poland already in two previous centuries. Storms will become more frequent with the warming climate, but it is difficult to predict how their intensity will change - says Dr. Mateusz Taszarek, "storm hunter" and forecaster from Adam Mickiewicz University.
Wrocław University of Science and Technology students will check whether it is possible to use a universal gripper that adapts to the shape of the object in space. Their experiment has qualified for the European Rexus/Bexus programme and will be launched on the programme`s rocket.
