The Two Faces of Capacitance: New Interpretations for Electrical Impedance Measurements of Perovskite Solar Cells and Their Relation to Hysteresis
Daniel A. Jacobs, Heping Shen, Florian Pfeffer +4
Perovskite solar cells are notorious for exhibiting transient behaviour not seen in conventional inorganic semiconductor devices. Significant inroads have been made into understand…

Total absorption of visible light in ultra-thin weakly-absorbing semiconductor gratings
Björn C. P. Sturmberg, Teck K. Chong, Duk-Yong Choi +7
The perfect absorption of light in subwavelength thickness layers generally relies on exotic materials, metamaterials or thick metallic gratings. Here we demonstrate that total lig…
