Abstract

Mesoscale-structured materials offer broad opportunities in extremely diverse
applications owing to their high surface areas, tunable surface energy, and
large pore volume. These benefits may improve the performance of materials
in terms of carrier density, charge transport, and stability. Although metal
oxides–based mesoscale-structured materials, such as TiO2, predominantly
hold the record efficiency in perovskite solar cells, high temperatures (above
400 °C) and limited materials choices still challenge the community. A novel
route to fabricate organic-based mesoscale-structured interfaces (OMI) for
perovskite solar cells using a low-temperature and green solvent–based process
is presented here. The efficient infiltration of organic porous structures
based on crystalline nanoparticles allows engineering efficient “n-i-p” and
“p-i-n” perovskite solar cells with enhanced thermal stability, good performance,
and excellent lateral homogeneity. The results show that this method
is universal for multiple organic electronic materials, which opens the door to
transform a wide variety of organic-based semiconductors into scalable n- or
p-type porous interfaces for diverse advanced applications.
