6 FAQs about [Influence of atmosphere on perovskite cells]
Does the atmosphere affect the performance of perovskite solar cells?
One aspect overlooked in earlier works is the effect of the atmosphere on device performance during operation. Here we investigate the degradation mechanisms of perovskite solar cells operated under vacuum and under a nitrogen atmosphere using synchrotron radiation-based operando grazing-incidence X-ray scattering methods.
Are perovskite solar cells stable?
Provided by the Springer Nature SharedIt content-sharing initiative Extensive studies have focused on improving the operational stability of perovskite solar cells, but few have surveyed the fundamental degradation mechanisms. One aspect overlooked in earlier works is the effect of the atmosphere on device performance during operation.
Do perovskite films increase PCE of solar cells?
The existence of these phases in perovskite films was reported to boost the PCE of perovskite solar cells 19, 20; however, an excessive amount of PbI 2 leads to poor device performance 21. These material properties and device efficiencies are of critical importance for this state-of-the-art research of degradation.
Do perovskite solar cells deteriorate under vacuum?
Understanding degradation mechanisms in perovskite solar cells is key to their development. Now, Guo et al. show a greater degradation of the perovskite structure and morphology for devices operated under vacuum than under nitrogen.
Does solvent vapor affect perovskite film morphology?
The results indicate the detrimental effects of such solvent vapors on the perovskite film morphologies and properties, which result in a significant drop of device PCE from 20.01% (control) down to only ~15% (DMF-treated).
Why do perovskite solar cells lose observable loss in different air mass conditions?
The estimated observable loss in different air mass conditions for perovskite solar cells is due to their strong absorption behaviour in the visible region. The higher AM can result in a shift of photon distribution into shorter wavelength regions which affect the perovskite solar cells.
