Perovskite solar cells (PSCs) have attracted a great deal of attention from the photovoltaic (PV) community because their remarkable performance, low production cost, and high potential to be integrated into other optoelectronic applications. Despite promise, challenges associated with operational stability drawn increasing over past decade. Owing unique structure fascinating properties such as...

The interband optical absorption of linearly polarized light by two-dimensional (2D) semimetals hosting tilted and anisotropic Dirac cones in the band structure is analysed theoretically. Supercritically (type-II) are characterized an that highly dependent on incident photon polarization frequency tunable changing Fermi level with a back-gate voltage. Type-II exhibit open surfaces large regions...
