TL;DR: In this paper, the surface growth of a low-dimensional perovskite layer on top of a 3D perovsite film was controlled by a structured perov-skite interface.
Paintable Carbon-Based Perovskite Solar Cells with Engineered Perovskite/Carbon Interface Using Carbon Nanotubes Dripping Method.
TL;DR: An attempt to enhance the performance of the paintable carbon-based PSCs is made using a modified solvent dripping method that involves dripping of the carbon nanotubes (CNTs), which is dispersed in chlorobenzene solution, results in increased open circuit voltage and fill factor, providing better contact at the perovskite/carbon interfaces.

Fabrication of graphene quantum dots via size-selective precipitation and their application in upconversion-based DSSCs
TL;DR: A novel approach to synthesize highly luminescent graphene quantum dots (GQDs) with well-defined sizes was explored based on simple oxidation of herringbone-type carbon nanofibers (HCNFs) and size-selective precipitation.

Size-controlled SiO2 nanoparticles as scaffold layers in thin-film perovskite solar cells
TL;DR: In this article, the authors investigated the effects of scaffold layers comprised of SiO2 NPs that were 15, 30, 50, 70, and 100 nm in diameter on the properties of perovskite films.
