Printing and Morphology Optimization: Thin Film Solar Cells Under In-Line Conditions
Abstract
PROJECT ABSTRACT We are proposing studies to investigate the fundamental principles underpinning the structure and morphology of a range of photovoltaic materials comprise of active layers that are polymer-, oligomer (small molecule)-, and perovskite-based. Using x-rays scattering studies on droplets of solutions of the polymers or oligomers mixed with PCBM or perovskites, the mechanism of crystal formation from the early stages of formation in solution will be examined by synchrotronor free electron laser-based methods. These fundamental studies will be augmented by in situ inline x-ray scattering and diffraction methods to monitor similar process as active layers are coated from solutions under industrially-relevant processing conditions. The performance of the devices will be related to the structure and morphology of thee active layers so that he morphology can be altered to optimize device performance. These studies will be augmented by in operando studies where the performance and morphology will be investigated as a function of time under an applied electric field. These combined studies are aimed at gaining a fundamental understanding of the active layer, optimizing the morphology by varying the preparation conditions, and optimizing device performance under conditions that are industrially-relevant.
