Researchers from ITMO University, Ioffe Institute of Physics and Technology and Harbin University of Engineering have developed a stable perovskite nanomemristor that can withstand more than 1,500 rewrite cycles and does not degrade after months. In addition, the researchers achieved record-low values of size and energy consumption - 70-80 nanowatts for a 130-160 nanometer perovskite single crystal.

This achievement could pave the way for ultracompact memristors and enable faster and more energy-efficient ultra-compact processors for neuromorphic computing. 

Indian solar module manufacturer Solex Energy has entered into a memorandum of understanding (MoU) with ISC Konstanz to engage in advanced research and development (R&D) and collaborate on technology for solar cell manufacturing.  

Under the MoU, ISC Konstanz will offer extensive technological assistance to Solex Energy in enhancing Solex’s upcoming TOPCon cell line and in the integration of advanced rear contact and cSi tandem/perovskite solar technologies. This collaboration will also facilitate the creation of Solex’s specialized in-house R&D line, leveraging ISC Konstanz’s patent portfolio to drive ongoing innovation within India.

Ricoh has announced that its perovskite solar cells have been installed in the Space Solar Cell Demonstration System (SDX) on HTV-X aboard the new unmanned cargo transfer spacecraft1, HTV-X1, developed by the Japan Aerospace Exploration Agency (JAXA), launched on Oct. 26. After HTV-X1 delivers supplies to the International Space Station (ISS), JAXA will conduct an in-orbit demonstration.

During the in-orbit demonstration, Ricoh's perovskite solar cells will be exposed to space conditions for approximately two months. During this period, the current-voltage (I-V) characteristics will be measured, and power generation performance and durability will be evaluated. Conventional satellite solar cells are heavy, which increases launch costs, and they face challenges such as degradation from cosmic rays (radiation traveling through space) and limited power generation under low-light conditions. Perovskite solar cells, by contrast, offer high power generation even at low illumination, strong resistance to cosmic rays, and potential for lightweight and flexible designs. These advantages make perovskite solar cells promising candidates for future use in space.

Researchers from China University of Petroleum (East China) and Qingdao Institute of Technology have reported a novel molecular strategy to tackle a known challenge in perovskite solar cells (PSCs) - the poor contact at the buried interface between the perovskite absorber and carrier extraction layers (CELs).

By introducing potassium sulfamate (H₂KNO₃S) as a bridging molecule between the SnO₂ CELs and the perovskite layer, the team achieved improvements in both device efficiency and stability. This multifunctional molecule, featuring –SO₃⁻ and –NH₂ groups along with K⁺ cations, simultaneously enhances interface wettability, passivates deep defect states, and strengthens the chemical anchoring between the layers.

Japanese Prime Minister Sanae Takaichi recently highlighted how homemade sources of energy like nuclear power and perovskite solar cells are important for the country. in what can be seen as a continuation of Japan’s push for energy self-reliance and sustainability. 

Addressing parliament, she said that domestically produced clean energy sources - especially perovskite solar technology - will be central to building a stable and affordable energy supply that supports both citizens’ livelihoods and Japan’s industrial competitiveness.

Researchers from Korea University, Tianjin University, Collaborative Innovation Center of Chemical Science and Engineering (Tianjin) and Haihe Laboratory of Sustainable Chemical Transformations have reported a dual-interface molecularly tailored  passivation (MTP) strategy that could improve the design of perovskite light-emitting diodes (PeLEDs).

Conventional solution-based passivation methods often induce unwanted secondary defects, hindering charge transport and device longevity. To address this, the team developed this solvent-free rub-on transfer method that enables precise molecular deposition while preserving the perovskite film’s integrity.

Researchers from China's Nanjing University, National Innovation Institute of Defense Technology, Beijing Institute of Technology, Chinese Academy of Sciences (CAS), Renshine Solar (Suzhou) and Australia's ANU (the Australian National University) have developed a dipolar passivation strategy that simultaneously reduces the defect density at the buried interface of mixed Pb-Sn perovskite and enables precise energy level adjustment at the HTL/perovskite interface.

This dipolar-induced passivation strengthens the ohmic contact at the interface, facilitating efficient hole injection into the HTL while driving electrons away from the HTL/Pb-Sn perovskite interface. The approach increases the carrier diffusion length to 8.3 μm characterized by terahertz probe and allows us to improve the PCE of Pb-Sn perovskite solar cells to 24.9%, along with a high open-circuit voltage (Voc) of 0.911 V, a Jsc of 33.1 mA cm^-2 and a high FF of 82.6%. 

Researchers from the University of Electronic Science and Technology of China (UESTC) recently developed a perovskite solar cell with a certified power conversion efficiency of 25.13%. This was realized by incorporating two-dimensional titanium carbide, known as MXene, as a multifunctional additive into the perovskite light-absorbing layer.

The new cell structure features a substrate of glass and indium tin oxide (ITO), an electron transport layer made of tin oxide (SnO₂), the MXene-modified perovskite absorber, a hole transport layer using Spiro-OMeTAD, and a gold metal contact.

Researchers from China's Anhui University of Science and Technology, Huainan Normal University and University of Electronic Science and of China have developed a cooperative perovskite-based cathode design that significantly improves solid oxide fuel cell (SOFC) performance at moderate operating temperatures.

The team developed the cathode based on PrOx (Pr₆O₁₁) and a Ruddlesden-Popper (RP) perovskite (Pr₄Ni₂.₁Co₀.₉O₁₀−δ). Using a modified Pechini method, they produced a range of compositions - Pr₁.₅Ni₀.₇Co₀.₃O₄−δ (P1.5NC), Pr₁.₇Ni₀.₇Co₀.₃O₄−δ (P1.7NC), Pr₁.₉Ni₀.₇Co₀.₃O₄−δ (P1.9NC), and Pr₂.₀Ni₀.₇Co₀.₃O₄−δ (P2NC) - to fine-tune the ratio of the two phases.

Japan-based Electric Power Development (J-POWER) has announced it has made an investment in Active Surfaces, a startup founded in 2022 that develops ultralight, flexible perovskite solar modules that peel-and-stick onto roofs, walls, and curved surfaces.

Through this investment, J-POWER will collaborate with Active Surfaces to conduct pilot tests utilizing the company’s products. As the next step, J-POWER aims to create new businesses by utilizing diverse perovskite solar cell products suited to various installation environments.
