Microfluidic‐Assisted Growth of Perovskite Single Crystals for Photodetectors

Planar-integrated single-crystalline perovskite photodetectors.

Hybrid perovskites are promising semiconductors for optoelectronic applications. However, they suffer from morphological disorder that limits their optoelectronic properties and, ultimately, device performance. Recently, perovskite single crystals have been shown to overcome this problem and exhibit impressive improvements: low trap density, low intrinsic carrier concentration, high mobility, a...

Mechanism for rapid growth of organic–inorganic halide perovskite crystals

Optoelectronic devices based on hybrid halide perovskites have shown remarkable progress to high performance. However, despite their apparent success, there remain many open questions about their intrinsic properties. Single crystals are often seen as the ideal platform for understanding the limits of crystalline materials, and recent reports of rapid, high-temperature crystallization of single...

Solution-Grown CsPbBr3 Perovskite Single Crystals for Photon Detection

Solution-Processed MoS2 /Organolead Trihalide Perovskite Photodetectors.

Integration of organic/inorganic hybrid perovskites with metallic or semiconducting phases of 2D MoS2 nanosheets via solution processing is demonstrated. The results show that the collection of charge carriers is strongly dependent on the electronic properties of the 2D MoS2 with metallic MoS2 showing high responsivity and the semiconducting phase exhibiting high on/off ratios.

Ultrahigh sensitivity of methylammonium leadtribromide perovskite single crystals toenvironmental gases

D ow nladed fom One of the limiting factors to high device performance in photovoltaics is the presence of surface traps. Hence, the understanding and control of carrier recombination at the surface of organic-inorganic hybrid perovskite is critical for the design and optimization of devices with this material as the active layer. We demonstrate that the surface recombination rate (or surface t...
