ThunderNIL è orgogliosa dei risultati ottenuti dal gruppo di Nicola Cefarin in merito alla nanostrutturazione della methylammonium lead iodide (MAPbI3) perovskite per applicazioni fotovoltaiche ed optoelettroniche.

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.
