From fabrication to degradation of solar cells
An in–situ study based on synchrotron radiation
Renjun Guo, Technische Universität München
Synopsis
Using synchrotron radiation–based grazing–incidence X–ray scattering techniques, we could monitor the structural and morphological transformations occurring during the fabrication process of spin–coating, slot–die coating and, sputtering techniques. In addition, we could continuously track the physical or chemical processes under operando conditions for different types of solar cells. The advantages of synchrotron radiation are well suited for kinetic structure analysis, and help understand the evolving nature of short–lived intermediates and transformation kinetics between material phases. After understanding fundamental mechanisms which limit the operational stability of new–generation solar cells, we could modify solar cells accordingly to make such new–generation solar cells real–world applications.
