TL;DR: In this paper, a sheet-to-sheet slot die coating process for perovskite solar cells and modules has been demonstrated on 6.5 × 13.5 cm 2 glass/ITO substrates.
Journal ArticleDOI
Recent progress in 2D/quasi-2D layered metal halide perovskites for solar cells
Jielin Yan,Jielin Yan,Weiming Qiu,Weiming Qiu,Gang Wu,Paul Heremans,Paul Heremans,Hongzheng Chen +7 more
TL;DR: In this article, a review mainly focuses on the application of 2D perovskite materials for solar cells, and a short outlook with their opinion is given to indicate the possible development trend for this kind of perov-skite material.
Journal ArticleDOI
