DESLOC Smart Lock, a global smart lock brand, has followed up on its earlier unveiling of the V150 Plus perovskite-solar smart lock with a full flagship lineup at CES 2026, introducing three models: V150 Plus, S150 Max, and K140 Plus. The company is positioning this range as a way to make front-door access smarter, more secure, and more convenient for everyday households.

At the center remains the V150 Plus, which integrates a perovskite solar panel directly into the lock to harvest ambient light and extend battery life, even in shaded porches, covered entryways, or typical indoor/outdoor lighting rather than relying on direct sun. Beyond its energy system, the V150 Plus also brings 3D facial recognition with liveness detection, an AI-powered GPTfinger 2.0 curved fingerprint sensor, and a removable 10,000 mAh backup battery, with pre-orders expected in Q2 2026 at under 300 USD.

BiLight Innovations has launched three flagship innovations at CES: a flexible and lightweight rollable photovoltaic (PV) curtain, a lithium-free perovskite electronic nameplate and a portable solar scroll.

Targeting core home and office scenarios, these products aim to redefine the boundaries of traditional photovoltaic applications. Through technological breakthroughs in flexibility, battery-free design, and scenario-based integration, the launch has attracted widespread attention across the show floor.

Lockin, an innovative vein recognition smart lock brand, has announced the new Aeon smart lock at CES.

The Aeon smart lock brings perovskite solar technology to door security, using high‑efficiency solar harvesting to drastically cut back on battery maintenance. Introduced alongside the V7 Max and Veno Pro Wireless around CES 2026, Aeon is positioned as the solar‑powered option in Lockin’s lineup, aimed at people who want a smart lock that quietly powers itself in the background instead of needing regular battery swaps or charging.

DESLOC Smart Lock, a global smart lock brand, has launched a smart lock powered by a perovskite solar system: the V150 Plus Solar Smart Lock. The product is designed for typical American suburban porches - bright yet rarely exposed to direct sunlight - and aimed at alleviating homeowners' concerns about smart lock power consumption. The product will be showcased at CES 2026.

Traditional solar smart locks have long struggled to deliver true perpetual power. Common crystalline-silicon solar panels cannot charge in low-light conditions, such as shaded porches. As a result, most so-called solar locks remain dependent on battery replacements every few months, frustrating homeowners who value convenience, security, and sustainability. The V150 Plus tackles this fundamental challenge. Its perovskite solar panel can start charging in very low light - just ≥200 lux, like dim indoor lighting. On a typical day, with about 4,000 lux of light, it produces enough energy to power the lock all day. 

Researchers from Nanchang University, Wuyi University and Jiangxi Science and Technology Normal University have reported a step forward in understanding how interfacial chemistry governs the performance and stability of halide perovskite memristors.

The study systematically explores how top electrode materials - including Au, Ag, Cu, and Al - impact the resistive switching behavior of quasi-2D CsPbBr₃ devices. By introducing a novel bilayer electrode architecture, the team successfully decoupled surface oxidation of the electrode from intrinsic redox processes at the perovskite/electrode interface. This breakthrough approach allowed for a clear separation of the chemical and physical contributions that dictate device performance.

Researchers from Huazhong University of Science and Technology and Eindhoven University of Technology recently reported a new class of gold–perovskite catalysts that enable efficient and selective oxidation of ethanol to acetaldehyde under aerobic conditions. 

The study focused on Au nanoparticles supported on Cu‑doped LaMnO₃ perovskites (Au/LaMn₁₋ₓCuₓO₃), where the optimized composition, Au/LaMn₀.₇₅Cu₀.₂₅O₃, achieved an acetaldehyde yield of 95% at 225 °C with a space‑time yield of 715 g AC gAu⁻¹ h⁻¹. The catalyst exhibited stable performance over extended reaction periods, outperforming previously reported Au/MgCuCr₂O₄ systems under comparable conditions.

Researchers from Korea's Institute for Basic Science, Korea Research Institute of Standards and Science and Chungbuk National University recently developed a new spectroscopic technique that enables real-time tracking of how perovskite nanomaterials change under light. 

The technique, called asynchronous and interferometric transient absorption spectroscopy (AI-TA), provides ultrafast measurements of excited-state dynamics and structural transformations in light-responsive materials. It overcomes major limitations of traditional ultrafast spectroscopy, which often requires long data acquisition times and can damage light-sensitive samples during measurement.

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.

A research team led by Professor In Soo-il from the Daegu Gyeongbuk Institute of Science and Technology (DGIST) recently developed a beta battery that directly consolidates radioactive isotope electrodes and perovskite absorption layers.

As the miniaturization of electronic devices accelerates, the demand for new power supply technologies that can minimize charging cycles surges. However, lithium and nickel-based batteries currently in widespread use have short lifespans and are vulnerable to heat and humidity, showing limitations in extreme environments. As an alternative to overcome these limitations, the technology of "betavoltaic cells," which can provide stable power for years to decades, is gaining attention.
