Paper Abstract

Hybrid perovskite solar cells with different crystalline grain size have been characterized by conventional techniques and additionally by low-frequency electrical noise spectroscopy. A clear correlation between the morphological structure of the perovskite grains, the energy disorder of the defect states, and the device performance has been demonstrated. In addition, the analysis of the temperature dependence of the noise amplitude has been also used to clearly identify the low-temperature transition between the orthorhombic and the tetragonal phases in perovskite solar cells and to extract important electronic parameters for both crystalline configurations.
