An international research group achieved the result on a 9 sq mm, triple-cation based, n-i-p structured perovskite cell using low solar concentration levels. Device instability, however, remains a challenge.

Cesium lead black perovskites could be interesting for solar cell development if their crystals are observed in their less efficient but more stable beta phase. The efficiency shortfall can be solved by healing emerging cracks in the surface of the cell using a choline iodide solution, according to an international team of scientists.

Scientists working at Switzerland’s École Polytechnique Fédérale de Lausanne, in the lab of renowned PV scientist Michael Grätzel, have developed a new method for testing perovskite solar cells that they say combines the advantages of laboratory and outdoor testing and will contribute to the creation of industry standards for characterizing perovskite stability.

Europe’s most important scientific research institutes have joined forces to make perovskite solar applications more than just a dream. The European Perovskite Initiative consortium is planning to draw up a perovskite white paper.

The module was developed by Insolight, a spin-off of Switzerland’s École polytechnique fédérale de Lausanne. The panel is based on tiny solar cells usually used for spaceflight applications and the limited amount used in the module makes it close to mass production, its creators claim.

Researchers from Kaunas University of Technology in Lithuania, working with the École Polytechnique Fédérale de Lausanne, have found an additive commonly used to improve performance in perovskite solar cells speeds up degradation of the material.

A team of scientists at Lausanne have calculated the costs and job impact of the 2050 Energy Strategy, in force since January. The results show the additional investment called for by the strategy is offset by savings on imported fuel and electricity.
