Ways To Slow Down The Degradation And Enhance The Stability Of Perovskite Solar Cells

The issues of the perovskite degradation and the stability of perovskite solar cells are studied in this article. The method of vacuum thermal deposition, spray pyrolysis, and spincoating methods are adopted for the fabrication of different constituents of solar cells to achieve good reproducibility and long lifetime for samples with high efficiency. The applied one-step coating method for creation of perovskite layer is described in detail. It is investigated what exactly leads to the degradation of perovskite solar cells under constant sunlight illumination, because this seems to be one of the biggest obstacles to their commercialization.
