Journal ArticleDOI

Stable perovskite solar cells with efficiency exceeding 24.8% and 0.3-V voltage loss.

TL;DR: Two fluorinated isomeric analogs of the well-known hole-transporting material Spiro-OMeTAD are developed and used as HTMs in PSCs and feature high efficiency, open-circuit voltage, and stability of perovskite solar cells.
Journal ArticleDOI

Conformal quantum dot–SnO2 layers as electron transporters for efficient perovskite solar cells

TL;DR: Replacing the commonly used mesoporous–titanium dioxide electron transport layer with a thin layer of polyacrylic acid–stabilized tin(IV) oxide quantum dots enhanced light capture and largely suppressed nonradiative recombination at the ETL–perovskite interface, resulting in a certified power conversion efficiency of 25.4% and high operational stability.
Journal ArticleDOI

The hydrothermal synthesis of mesoporous TiO2 with high crystallinity, thermal stability, large surface area, and enhanced photocatalytic activity

TL;DR: In this article, a well-defined spherical mesoporous TiO2 was prepared from a poly(ethylene glycol)-poly(propylene glycol) based triblock copolymer and titanium isopropoxide mixed with 2,4-pentanedione by using a simple sol-gel approach in aqueous solution.
