This review first presents the fundamentals of the TE method, with an emphasis on the growth mechanism of perovskite films. This is followed by the progress of thermally evaporated perovskite-based optoelectronic devices, especially solar cells and light-emitting diodes. Last, the device-oriented ...
The results show that vacuum thermal evaporated CuI films have no obvious influence on perovskite underlayer and 200 nm thick CuI film has the best carrier extraction ability. To further improve the stability of the device, reduced graphene oxides are introduced to avoid the accelerated attenuation ...

After the gas evolution stopped, the mixture was stirred overnight, and the solvent was evaporated to a reduced volume (5 mL). Methanol (10 mL) was added to the reaction mixture to precipitate a yellow powder that was filtered, rinsed with methanol, and dried under reduced pressure. ...
Tin oxide (SnO x ) as a functional layer, such as electron transport layer (ETL) or buffer layer, is widely used in perovskite solar cells (PSCs). However, SnO x prepared by spin coating is not suitable to be applied to the solar cells with large area or rough substrates. In this ...

Besides, a post-annealing treatment of evaporated SnO(2)is proved obbligato to achieve an ideal crystallinity improvement. Furthermore, to remove the antisolvent method for perovskite, methyl ammonium acetate (MAAc) worked as an additive into the perovskite precursor for a pure MAPbI(3 )film to ...
