TL;DR: A new metal halide perovskite photovoltaic cell that exhibits both very high solar-to-electric power-conversion efficiency and intense electroluminescence is reported on.
Journal ArticleDOI
Polymer-templated nucleation and crystal growth of perovskite films for solar cells with efficiency greater than 21%
Dongqin Bi,Chenyi Yi,Jingshan Luo,Jean-David Decoppet,Fei Zhang,Shaik M. Zakeeruddin,Xiong Li,Anders Hagfeldt,Michael Grätzel +8 more
TL;DR: In this article, an approach to prepare perovskite films of high electronic quality by using poly(methyl methacrylate) (PMMA) as a template to control nucleation and crystal growth is presented.
Journal ArticleDOI
A vacuum flash-assisted solution process for high-efficiency large-area perovskite solar cells.
Xiong Li,Dongqin Bi,Chenyi Yi,Jean-David Decoppet,Jingshan Luo,Shaik M. Zakeeruddin,Anders Hagfeldt,Michael Grätzel +7 more
TL;DR: A simple vacuum flash–assisted solution processing method is devised to obtain shiny, smooth, crystalline perovskite films of high electronic quality over large areas, which enables the realization of highly efficient large-area PSCs for practical deployment.
Journal ArticleDOI
Effect of Different Hole Transport Materials on Recombination in CH3NH3PbI3 Perovskite-Sensitized Mesoscopic Solar Cells.
TL;DR: It is shown that the nature of the HTM is essential for charge recombination and elucidates that finding an optimal HTM for the perovskite solar cell includes controlling the perOVskite/HTM interaction.
Journal ArticleDOI
Using a two-step deposition technique to prepare perovskite (CH3NH3PbI3) for thin film solar cells based on ZrO2 and TiO2 mesostructures
