‘Perovskite materials for photovoltaic applications'

Abstract: Halide perovskite materials have attracted wide research interests owing to their direct bandgaps, long-range electron and hole transport lengths, and high absorption coefficients. In this seminar, perovskite materials are first introduced. A method to compute dielectric constant profiles using density functional theory (DFT) is presented with some results as illustration. Then an experimental study of several interfacial layers used in perovskite solar cell devices is shown. Finally, the application of perovskite materials in silicon-based tandem solar cells is addressed.
