Carbon-based perovskite solar cell relying on phosphorene achieves 15.58% efficiency

The result is the best efficiency ever recorded for a carbon-based PV cell using unconventional hole transporting materials to date. The device was built with a hole transparent layer based on electrochemically produced large-area phosphorene flakes, which reportedly enable the required band energy alignment within the cell. A research group in Australia has designed a perovskite solar cell using a carbon electrode and a hole transport layer (HTL) made of a special kind of 2D material known as phosphorene (eBP). This material consists of a single layer of black phosphorus (BP) and is analogous ...
