General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for "Energy efficiency".

Application

2D perovskites have been used as the active material in may applications such as light emmiting diodes, phototransistors, and solar cells. Unlike 3D perovskites, these layered materials give higher moisture stability and longer device lifetimes.
Di-n-butylammonium methylammonium lead(II) heptaiodide can be used for fabrication of perovskite materials for solar cells, light-emitting diodes (LEDs), photodetectors, and lasers.

Organometal halide perovskites exhibit large bulk crystal domain sizes, rare traps, excellent mobilities and carriers that are free at room temperature-properties that support their excellent performance in charge-separating devices. In devices that rely on the forward injection of electrons and

Recently, two-dimensional (2D) organic-inorganic perovskites emerged as an alternative material for their three-dimensional (3D) counterparts in photovoltaic applications with improved moisture resistance. Here, we report a stable, high-gain phototransistor consisting of a monolayer graphene on hexagonal boron nitride (hBN) covered
