Efficient charge transfer from organometal lead halide perovskite nanocrystals to free base meso-tetraphenylporphyrins

Abstract

We reported the efficient charge transfer studies from methylammonium lead halide, MAPbX3 (X = Br, I), perovskite nanocrystals (PNCs) to 5,10,15,20-tetraphenylporphyrin (TPP).

“…identified the charge transfer of perovskite with mesoporous titanium dioxide. Previous studies explored the charge transfer phenomenon from electron donor perovskites to acceptor groups such as fullerenes, carbon nanotubes, perylenes, RhB, benzoquinone, TiO 2 , and porphyrins . For example, Wu et al revealed the timescale of ultrafast electron transfer from perovskites to phenothiazine and benzoquinone.…”

Subsequently, Long et al 43 reported the ultrafast interfacial charge transfer from PNCs to TiO 2 .…”

Boosting the stability of lead halide perovskite nanocrystals by metal–organic frameworks and their applications

“…2 Their high power conversion efficiency (PCE), high photoluminescence quantum yields (PLQY), narrow emission bands, and tunability of band gaps by size, shape, dimensionality, and composition make them ideal aspirants for optoelectronic devices, e.g., solar cells, LEDs, lasers, specific photodetectors, and visible-light communication. [3][4][5][6][7][8][9][10][11] Nonetheless, the main weakness of lead halide perovskite is the poor chemical stability under ambient conditions. These are very sensitive in the presence of moisture, air, light, and temperature due to their low formation energy.…”
