The German research institute said it utilized a hybrid manufacturing route to deposit the perovskite solar on the cell's top PV device based on an industrially textured silicon heterojunction technology. For the bottom subcell, a standard silicon solar cell was used. Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) announced today it achieved a power conversion efficiency of 31. 6% for a perovskite-silicon tandem solar cell. The result was confirmed by Fraunhofer ISE's calibration laboratory CalLab. The researchers explained that that cell consists of a top perovskite ...Den vollständigen Artikel lesen ...
