ThunderNIL is proud of the results obtained by the team of Nicola Cefarin et. al about the nano-patterning of the methylammonium lead iodide (MAPbI3) perovskite for photovoltaic and optoelectronic applications.
Nanostructuring methylammonium lead iodide perovskite by ultrafast nano-imprinting lithography
We report the nanopatterning of the methylammonium lead iodide (MAPbI3) perovskite, a polycrystalline hybrid organic-inorganic semiconductor with very promising perspectives for photovoltaic and optoelectronic applications. Nanopatterning of MAI is obtained via Pulsed-NIL technology, an ultrafast version of the thermal nanoimprint lithography (NIL) based on stamps with integrated heaters. By Pulsed-NIL we were able to replicate onto the hybrid perovskite structures with details at the sub-100 nm scale, in spite of its crystalline nature. This work shows a new possibility for the exploitation of organo-metal halide perovskites in optoelectronic devices with more complex architectures than just planar films.
