Mark your calendars for the 2025 Perovskite Connect event!

We are excited to announce the 2025 Perovskite Connect Conference, scheduled for October 22-23, 2025, in Berlin, Germany.

This in-person event will unite leading experts from academia and industry to explore the latest advancements and challenges in perovskite technology. Distinctively, the conference will focus on an industry-oriented approach, emphasizing networking opportunities and strategies for market entry rather than solely technical discussions. Attendees can look forward to engaging activities such as tours, masterclasses, exhibition and more!

Perovskite Connect, organized by Perovskite-Info and Techlbick, will be co-located with the Future of Electronics RESHAPED event, a major gathering for the printed, flexible, large-area, and roll-to-roll (R2R) electronics sectors. This synergy is key, as these technologies are integral to the development and mass production of perovskites. Together, these events are expected to attract over 600 participants, feature 80 exhibitors, and host 70 insightful talks. In addition to the Berlin show, Perovskite Connect includes a year-long program of online events, and access to over a thousand past related webinars and presentations.

Adding azetidinium iodide can improve the efficiency and stability of wide-bandgap perovskite solar cells

Researchers from China's Tianjin University of Technology, Zhejiang Sci-Tech University, University of Electronic Science and Technology of China, North China Electric Power University and South China University of Technology have shown that the introduction of azetidinium iodide (AZI) into the precursor solution of a 1.77 eV bandgap FA0.8Cs0.2Pb(I0.6Br0.4)3 perovskite significantly improves the efficiency and stability of the perovskite cells. 

Devices fabricated with 2 mol% AZI (relative to FAI, noted as AZ2) in perovskite layer exhibited a high PCE of 19.16 % and a high open-circuit voltage of 1.31 V. When stored under nitrogen atmosphere and illuminated under 1 sun conditions for 300 h, AZ2 device retained 80 % of the initial values.

Researchers use machine learning to develop a process for finding optimal materials for perovskite solar cells

A team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) and the Karlsruhe Institute of Technology (KIT) have developed a closed process for finding optimal high-performance materials for perovskite solar cells (PSC). The approach introduced in the study combines computer-assisted modeling, autonomous synthesis platforms and quantum theoretical calculations for characterizing molecules in order to be able to predict suitable material combinations and to test them in an automated fashion.

“What is the best way to find new materials for photovoltaic components that already have the optimal properties for this application?” This is the question that Prof. Christoph Brabec, speaker of the FAU Profile Center Solar and Chair of Materials Science and Engineering, has spent over a year exploring together with 22 researchers from the disciplines of chemistry, materials science and engineering, computer science and electrical engineering.

Researchers 3D print customizable radiation detectors based on perovskite materials

Radiation detectors, which convert radiation into measurable light signals, currently come in fixed shapes like blocks or cylinders because they are made by growing crystals at extremely high temperatures – around 1700 °C. These rigid shapes make it difficult to measure radiation doses accurately around irregularly shaped tumors or in tight spaces. Previous attempts to create detectors in custom shapes have focused on plastic materials that can be easily molded, but these plastic detectors perform poorly because they lack the heavy elements needed to efficiently capture radiation. Scientists have tried mixing metal particles into plastics to improve their detection ability, but this often results in uneven distribution of the particles and poor overall performance.

A research team from several institutions in Italy and Switzerland has now developed a new approach using stereolithography (SLA), a precise form of 3D printing that builds objects by hardening light-sensitive liquid materials layer by layer. This marks the first successful use of SLA to fabricate 3D-printed scintillators, a breakthrough in radiation detection technology. The team mixed microscopic crystals of cesium lead bromide (Cs4PbBr6), a perovskite material, into a liquid resin that hardens when exposed to ultraviolet light. Perovskites have gained significant attention in recent years because they efficiently convert various forms of energy into light. Their crystal structure, which contains heavy elements like lead, makes them particularly effective at detecting radiation.

Researchers improve understanding of perovskite solar cell degradation

Researchers at the Canadian University of Saskatchewan recently gained insight as to why solar cells made with lead halide perovskite degrade prematurely. These discoveries could advance the reliability these solar cells.

In experiments conducted at the Canadian Light Source (CLS) synchrotron, Dr. Tim Kelly, a professor of chemistry at USask, sought to determine why perovskite-based solar cells fail under certain conditions. The researchers initially suspected that the issue lay in the perovskite formulation. By employing X-ray diffraction to analyze the material’s atomic structure in real-time, the team observed that humidity played a critical role in cell degradation. Moisture caused ions within the perovskite to mobilize, migrate to the electrode, and corrode it, rendering the device inoperative.

Chinese researchers use perovskites to develop polarization photodetectors mimicking desert ant

Researchers from the Chinese Academy of Sciences (CAS), Beihang University and Imperial College London have developed an on-chip integrated polarization photodetector (pol-PD), drawing inspiration from the unique polarization vision of desert ants.

Pol-PDs have widespread applications in geological remote sensing, machine vision and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniaturize and integrate. The researchers observed that desert ants can navigate back to their nests across barren landscapes without landmarks, thanks to their compound eyes' ability to detect polarized sunlight. They aimed to mimic this capacity with their pol-PD.
