TL;DR: In this article, a comprehensive overview of perovskite semiconductors is presented and an informed perspective of where this field is heading and what challenges we have to overcome to get to successful commercialization.
Journal ArticleDOI
Lead(II) Propionate Additive and a Dopant-Free Polymer Hole Transport Material for CsPbI2Br Perovskite Solar Cells
Senol Öz,Ajay Kumar Jena,Ashish Kulkarni,Kazuhiro Mouri,Takamichi Yokoyama,Izuru Takei,Feray Ünlü,Sanjay Mathur,Tsutomu Miyasaka +8 more
TL;DR: All-inorganic perovskites (CsPbI3 and CspbI2Br) are becoming popular in photovoltaics as mentioned in this paper, owing to their greater thermal stability compared to organic inorganic hybrid perovsites.
Journal ArticleDOI
Understanding the interplay of stability and efficiency in A-site engineered lead halide perovskites
Feray Ünlü,Eunhwan Jung,Jinane Haddad,Ashish Kulkarni,Senol Öz,Heechae Choi,Thomas Fischer,Sudip Chakraborty,Thomas Kirchartz,Thomas Kirchartz,Sanjay Mathur +10 more
TL;DR: A-site cation management is governed by stability and charge neutrality of the lattice, and the choices include Cs+-cations and organic cations such as CH3NH3+ or CH(NH2)2+ and combinations thereof as mentioned in this paper.
Journal ArticleDOI
Towards the environmentally friendly solution processing of metal halide perovskite technology
TL;DR: In this paper, a review of the research progress of solution-processable perovskite material using low-toxic and green solvent alternatives is presented, where the authors discuss the advantages and challenges of each type of green solvent based on their performance in metal halide perovsite technology.
