Perovskite based diodes using both vacuum and solution processed materials will be presented. Our group has developed several perovskite based solar cells, using vacuum based perovskite preparation methods reaching power conversion efficiencies as high as 20 % in a planar single junction device and similar performance in tandem devices. Driving these devices under forward bias (in LED modus) allows to obtain important device characteristics. The endeavors related to highly luminescent perovskites and their integration into light-emitting diodes will also be commented upon. The integration of perovskite diodes between semitransparent metal electrodes leads to cavity resonance behavior which can be tuned by the thickness of the perovskite layer. Using photoluminescence as a detection tool we study the effect of interface materials on the light emission properties of different perovskite thin films prepared using vacuum sublimation techniques. Using combination of organic charge transport layers and perovskite emitters the photoluminescence quantum yield is increased.
