Journal ArticleDOI
Ambipolar solution-processed hybrid perovskite phototransistors
TL;DR: The phototransistors based on hybrid perovskite films are investigated and provide direct evidence for their superior carrier transport property with ambipolar characteristics and exhibit an ultrafast photoresponse speed of less than 10 μs.
Journal ArticleDOI
Temperature-dependent excitonic photoluminescence of hybrid organometal halide perovskite films
TL;DR: This work investigated in detail the cryogenic steady state photoluminescence properties of a prototypical hybrid perovskite CH3NH3PbI3-xClx and revealed an abnormal blue-shift of the band gap in the high-temperature tetragonal phase.
Journal ArticleDOI
Self-assembled Monolayer Enables HTL-free Organic Solar Cells with 18% Efficiency and Improved Operational Stability

TL;DR: In this paper, a self-assembled monolayer (SAM) 2PACz was used as a hole-selective interlayer functionalized directly onto the indium tin oxid.
Journal ArticleDOI
Heterostructured WS2 /CH3 NH3 PbI3 Photoconductors with Suppressed Dark Current and Enhanced Photodetectivity.
Chun Ma,Yumeng Shi,Weijin Hu,Ming-Hui Chiu,Zhixiong Liu,Ashok Bera,Feng Li,Hong Wang,Lain-Jong Li,Tom Wu +9 more
TL;DR: Heterostructured photoconductors based on hybrid perovskites and 2D transition-metal dichalcogenides are fabricated and characterized and show high performance with on/off ratio of 10(5) and responsivity of 17 A W(-1) .
Journal ArticleDOI
Solution-Grown Monocrystalline Hybrid Perovskite Films for Hole-Transporter-Free Solar Cells.
