A research team, led by Professor Yong-Young Noh and Dr. Youjin Reo from the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology), has developed p-channel Sn²⁺-halide perovskite TFTs using a thermal evaporation approach with inorganic caesium tin iodide (CsSnI₃). 

The project was a collaborative effort with Professors Ao Liu and Huihui Zhu from the University of Electronic Science and Technology of China (UESTC) and resulted in the development of high-performance, stable p-channel CsSnI₃-based TFTs using a commercially compatible vapor-deposition approach with PbCl₂ as an additive. The volatile chloride triggers solid-state reactions and the conversion of as-evaporated precursor compounds. This facilitates the formation of high-quality and uniform perovskite films, and also modulates the high hole density, making them suitable for use as channel layers. The optimized CsSnI₃:PbCl₂ TFTs delivered average µFE of around 34 cm2 V⁻¹ s⁻¹, on/off ratio of around 10⁸ and storage stability of more than 150 days. The team also demonstrated a large-scale Sn²⁺-halide perovskite TFT array that overcomes the technical challenges faced in the solution process. The vapor-deposited TFTs could be used in backplanes for organic light-emitting diode displays, or in logic devices and circuits for monolithic three-dimensional integration, where low process temperatures are required.

Seiko Epson Corporation and Epson X Investment Corporation have invested in South Korean Gosan Tech through a joint fund, the EP-GB L.P. 

Founded in 2015, Gosan Tech develops and sells inkjet systems for fabricating organic light-emitting diode (OLED) displays and perovskite solar cells. Through its work in this field, it has developed an ink supply system, pressure control technology, and simulation technology that enable it to achieve excellent ink droplet uniformity and precision. Gosan Tech is expanding its business in three areas: information technology, including OLED display fabrication and direct parts marking; the environment, with inkjet systems for perovskite solar cells; and bio-medical, including drug deposition, tissue engineering, and diagnostic.

Researchers at China's Shanghai University, Southern University of Science and Technology, The University of Hong Kong, Yunnan University, Beijing Institute of Technology and Japan's Yamagata University have developed a stable, efficient and high-color purity hybrid light-emitting diodes (LEDs) with a tandem structure, by combining perovskite LED and commercial organic LED technologies.

Perovskite-based LED technology can have tunable emission wavelength in visible light range as well as narrow linewidth, which makes it a promising contender among current light-emitting display technologies. However, it still suffers from severe instability driven by electric field. The research team in this work set out to tackle this challenge, by developing a method to create efficient and stable hybrid perovskite-organic light-emitting diodes.

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), led by Prof. Peidong Yang, have developed a new 3D printing ink based on perovskite materials, that exhibits near unity photoluminescence quantum yield (PLQY). Interestingly, as it is a 3D printable ink, it is possible to create luminescent objects from it, as seen in the image below:

The researchers brand the new ink as 'supramolecular ink', and say it is produced without any rare metals. It is a combination of several powders containing hafnium (Hf) and zirconium (Zr), and is made at room temperatures. In a process called supramolecular assembly, tiny molecular building block structures are self-assembled within the ink. These supramolecular structures enable the material to achieve stable and high-purity synthesis at low temperatures.

Researchers at Imec have reported a metal halide perovskite LED (PeLED) stack that emits 1,000x more light “than state-of-the-art OLEDs”. The team developed a transparent PeLED architecture, that combines low optical losses with excellent current-injection properties. 

In this work, the team showed that perovskite semiconductor optical amplifiers and injection lasers are within reach using this type of transparent PeLED.
