Researchers at China's Shanghai University of Electric Power have used dibenzoylmethane (DBM) as a precursor additive introduced in order to regulate the crystallization of CsPbI₂Br perovskite while passivating its associated defects. 

Inorganic CsPbI₂Br perovskite solar cells (PSCs) have attracted massive interest but the tendency towards unruly crystallization and poor film quality of inorganic CsPbI₂Br perovskites are major factors limiting their performance improvement. In their recent work, the scientists used DBM additive engineering for efficient and stable carbon-based CsPbI₂Br PSCs.

A recent collaboration between the Hybrid³ team at Duke University (led by Professor Volker Blum) and SpringerMaterials has resulted in an insightful project called the Hybrid Perovskite Data Set, which enables researchers to compare and analyze different materials and optimize their properties for specific applications.

The huge number of variations of perovskite materials can make it challenging to find the most suitable material for a specific application. Now, researchers can use the data set to design new materials and experiment with new compositions, making the discovery of new materials more efficient and effective.

Researchers from India's Chiktara University have reported improved stability and performance of organic-inorganic perovskite solar cells by applying a strategy called bandgap grading.

The method is based on enabling the cell perovskite absorber to collect a wider range of light photons by modifying its thickness and characteristics. The team explains that its recent study demonstrates the effectiveness of both linear and parabolic bandgap grading strategies in optimizing light absorption and boosting performance, showing its potential. 

Researchers from the Hong Kong University of Science and Technology, Sun Yat-sen University and Nanjing University of Science and Technology have uniformly grown all-inorganic perovskite quantum wire arrays by filling high-density alumina nanopores on the surface of Al fibers with a dip-coating process. 

Fiber light-emitting diodes (Fi-LEDs), which can be used for wearable lighting and display devices, could be a key component for fiber/textile electronics. However, as a number of challenges exist with this technology, researchers are trying to address issues like on device fabrication with fiber-like substrates, as well as on device encapsulation.

Israel-based SOLRA-PV showcases its cutting-edge indoor perovskite solar panel technology in action by successfully powering an entire IoT device setup. The system comprises an indoor panel, an environmental sensor, Bluetooth, and power management.

As you can see in the video, the prototype device performs a measurement every 10 minutes and transmits it to the smartphone. Utilizing SOLRA-PV's panels effectively captures indoor light for power generation, thus paving the way for the development of battery-free devices. The Company states that under indoor light conditions of 1000 lux, the panel produces 0.5 mW of power.

Researchers from King Abdullah University of Science and Technology (KAUST), Kaunas University of Technology and Helmholtz-Zentrum Berlin (HZB) recently improved on a previous development of record-breaking solar cells a few years ago, by expanding their invention: the self-assembled monolayers (SAMs) can now be applied not only in inverted but also in regular structure perovskite solar cells.

Self-assembling molecules arrange themselves into a single-molecule-thick layer and in this case, they act as an electron-transporting layer in solar cells.

Researchers at China's Nanjing University of Science and Technology, Hong Kong Baptist University and Southwest University have introduced a tandem device that incorporates an organic photodiode (OPD) and a perovskite light emitting diode (PeLED), enabling simultaneous light detection and emission in one compact device, prepared by all-solution fabrication process. 

The team found that precise control of interfacial properties plays a critical role in establishing the all-solution processed OPD/PeLED multi-layered dual-function device which is critical for charge transport, recombination, and generation. 

It was reported that the Japanese government estimates the need for electricity output to rise 35% to 50% by 2050 due to growing demand from semiconductor plants and data centers backing artificial intelligence (AI). 

It was mentioned that the country is counting on perovskite solar cells, floating offshore wind farms, restarts of nuclear power plants and the introduction of next-generation reactors to meet the demand.

Researchers from Germany's Karlsruhe Institute of Technology (KIT) have developed a scalable two-step evaporation and inkjet process for perovskite thin-film solar cells. The new technique is said to enable champion cells with the same efficiencies as those made with the spin coating process.

The process is described as a scalable and reliable technique for high-quality perovskite deposition, which combines the use of an evaporated lead iodide layer with inkjet-printed organic perovskite precursor materials. It is also said to exhibit high reproducibility and potential for conformal growth on textured silicon, and that provide films that are free of drying effects and toxic solvents.

China-based RenShine Solar has announced that following the completion and commissioning of its 150MW perovskite photovoltaic module project in January, 2024, the Company's 1.2*0.6㎡ commercial size single-junction perovskite was certified by the China Institute of Metrology. The steady-state efficiency of the entire module area reportedly reaches 18.4%.

The production line aims to achieve mass production of 1.2m*0.6m perovskite modules with 20% efficiency by mid-2024. It plans to develop gigawatt-scale production lines to further expand its capacity.
