Perovskite-Info: the perovskite experts

Perovskite-Info is a news hub and knowledge center born out of keen interest in the wide range of perovskite materials.

Perovskites are a class of materials that share a similar structure, which display a myriad of exciting properties like superconductivity, magnetoresistance and more. These easily synthesized materials are considered the future of solar cells, as their distinctive structure makes them perfect for enabling low-cost, efficient photovoltaics. They are also predicted to play a role in next-gen electric vehicle batteries, sensors, lasers and much more.

Researchers achieve record efficiency of 25.8% for single junction perovskite solar cell

Researchers at South Korea’s Ulsan National Institute of Science and Technology (UNIST) and Pohang University of Science and Technology report a power conversion efficiency of 25.8% for a single junction perovskite solar cell, by forming a coherent interlayer between electron-transporting and perovskite layers to reduce interfacial defects.

The cell was built with an interlayer between a tin(IV) oxide (SnO2) electron-transporting layer and a layer made of a halide perovskite layer by coupling chlorine-bonded SnO2 with a perovskite precursor containing chlorine. “This interlayer has atomically coherent features which enhance charge extraction and transport from the perovskite layer; and fewer interfacial defects,” the academics explained.

Saule Technologies gets closer to going public on NewConnect

Saule Technologies, developer and manufacturer of perovskite solar cells, recently announced that it is 'making good progress towards getting listed on the NewConnect Alternative Trading System'.

Saule and its shareholders, including the majority holder, Columbus Elite Global S.A. (formerly Blumerang Investors S.A.), have signed an investment agreement, setting the rules for Columbus Elite Global (CEG) to acquire Saule’s shares. With this transaction, Saule will become part of the CEG capital group, which is listed on NewConnect. In return for transferring their shares to Columbus Elite Global, Saule’s shareholders will get shares in the higher share capital of CEG.

Inkjet-printed flexible perovskite LEDs could open the door to new applications

Researchers from Florida State University and Washington University in St. Louis have developed a new material for displays and a novel way to fabricate it—using an inkjet printer. The team used organometal halide perovskites — with a novel twist.

The traditional way to create a thin layer of perovskites, which is in liquid form, is to drip it onto a flat, spinning substrate, in a process known as spin coating. As the substrate spins, the liquid spreads out, eventually covering it in a thin layer. From there, it can be recovered and made into perovskite LEDs, or PeLEDs. A lot of material, however, is wasted in that process—as the substrate spins at several thousand RPM, some of the dripping perovskite splatters and flies away, not sticking to the substrate. The researchers substituted this process with one based on an inkjet printer.

New technique could help create better perovskite materials

A recent study by Lawrence Berkeley National Laboratory (Berkeley Lab), Technische Universität München, EPFL and The Pennsylvania State University has found that solar materials manufacturing could be aided by a new instrument that uses two types of light – invisible X-ray light and visible laser light – to probe a perovskite material’s crystal structure and optical properties as it is synthesized.

“When people make solar thin films, they typically have a dedicated synthesis lab and need to go to another lab to characterize it. With our development, you can fully synthesize and characterize a material at the same time, at the same place”, said Carolin Sutter-Fella, a scientist at Berkeley Lab's Molecular Foundry.

IIT Madras team designs perovskite-based white light emitters for LEDs

Researchers at the Indian Institute of Technology Madras (IIT-M) have developed a perovskite-based white light emitter for use in energy-efficient Light Emitting Diodes or LEDs.

As conventional LED materials cannot emit white light, to produce white light, specialized techniques such as coating blue LED with yellow phosphor and combining blue, green, and red LEDs have been used, along with a worldwide search for materials that can directly emit white light.

The DoE awards $1.25 million to perovskite research projects, issues an RFI for perovskite efficiency targets

The US Department of Energy (DoE) awarded nearly $40 Million for grid-decarbonizing solar technologies projects. The DoE awarded the funds to 40 research projects, several of which are perovskite related. We'll list the perovskite projects (which were awarded a total of $1.25 million) below.

The DoE also issued a request for information (RFI) to gather input on efficiency, stability and replicability performance targets for perovskite photovoltaic devices that could be utilized to demonstrate technical and commercial readiness for future funding programs.
