GraphEnergyTech recently shared an update on its recent progress, funding goals, and strategic direction within the solar energy sector.

GraphEnergyTech’s selection for Japan’s Keihanna Global Acceleration Program (KGAP+) marks a significant milestone as the company’s graphene-enhanced carbon electrode technology aligns closely with Japan’s advanced perovskite solar cell ecosystem. A portfolio company of Frontier IP Group PLC (LSE:FIPP, FRA:8WT), GraphEnergyTech is currently raising a minimum of £3 million in a seed funding round. The capital will be used primarily to expand production capacity and accelerate R&D focused on silicon solar cells. However, CEO Dr. Thomas Baumeler noted that the company also has “a solution that fits particularly well with perovskite solar cells.”

Swansea University is teaming up with Power Roll for a new collaborative project to appraise novel characterization techniques for perovskite solar cells (PSCs). The initiative, AI-Enhanced Perovskite Manufacturing using Inline Metrology, Performance Assessment and Characterization Techniques (AI-IMPACT), has won Innovate UK funding.

AI-IMPACT aims to address major capability gaps in inline and end-of-line testing for PSCs at scale and high throughput. Without these advancements, PSC companies could face significant hurdles in achieving product accreditation. The project will deliver new inline testing and characterization tools specifically designed for perovskite devices in manufacturing environments, alongside the development of robust stability guidelines to support industry standards.

According to reports, Chinese PV manufacturer TCL Zhonghuan Renewable Energy Technology (TZE) has disclosed its strategy to acquire a controlling stake in DASOLAR. 

The proposed transaction is positioned as a capital-level integration focused on n-type PV technologies across materials, cells, and modules. TZE is identified for its G12 silicon wafer production and advances in n-type wafer thinning and crystal growth processes. DASOLAR, according to TZE, is described as a producer of TOPCon cells and modules with reported industry efficiency records and global shipment rankings in 2024. The companies have already maintained an upstream–downstream partnership within the n-type PV value chain. 

Perovskite-Info is happy to announce the 2026 edition of The Perovskite Handbook. This book is a comprehensive guide to perovskite materials, applications and industry. Perovskites are an exciting class of materials that feature a myriad of exciting properties and are considered the future of solar cells, displays, sensors, LEDs and more.

An international team of researchers, including ones from Iritaly Trading Company, École Polytechnique Fédérale de Lausanne (EPFL), University of Rome Tor Vergata, Argonne National Laboratory and Italy-based Greatcell Solar, has reported a co-crystal engineering approach to improve the long-term stability of perovskite solar cells and modules.

The team used a neutral molecule, benzoguanamine, as a linker in low-dimensional perovskites, replacing conventional ionic molecules, to form a co-crystal. By applying this co-crystal layer onto the perovskite layer, they achieved power conversion efficiency of 23.4% in small-area solar cells, and 23.1% and 18.5% on solar modules with active areas of 9.0 cm² and 48 cm², respectively. The solar modules retained more than 95% and 98% of their initial efficiency after >5,000 h of 1-sun light soaking and >1,000 h of ultraviolet-ray exposure, respectively, at maximum power point conditions. They also retained more than 91% of their initial efficiency after >5,000 h of continuous thermal stress at 85 °C.

Researchers from China's Zhejiang University, Wenzhou University, Central South University and Denmark's Aalborg University have developed an energy‑efficient way to engineer perovskite nanocrystals in glass, unlocking stable, flexible random lasers for advanced photonic applications.

By using low‑temperature thermal strategies far below the glass transition temperature, they precisely tune nanophase separation and ion distribution inside perovskite nanocrystal domains, achieving controllable photoluminescence and lasing behavior in glass composites. Through carefully controlled nanophase separation and crystallization, the team creates hierarchical “PNCs‑in‑glass” structures that dramatically boost light scattering, enabling continuous‑wave single‑mode random lasing with an ultralow threshold of just 52.6 milliwatts per square centimeter. 

UtmoLight has partnered with the University of New South Wales (UNSW) to jointly establish an International Joint Perovskite Laboratory. 

The laboratory is supported by UtmoLight’s Global Innovation Center and features over 6,000 m² of laboratory space with a professional R&D team of more than 100 researchers. Through the joint lab, the partners will conduct collaborative research on cutting-edge perovskite technologies, build a talent co-development and knowledge-sharing mechanism, and jointly promote the industrialization of perovskite PV technologies.

Trinasolar has announced that its innovation platform has achieved a critical technological milestone. Setting its sights on Space PV, the platform has reportedly "broken the world record for power output with its large-area (3.1 m²) perovskite/crystalline silicon tandem modules, reaching 886W". This achievement, along with significant efficiency gains in perovskite/P-type heterojunction (HJT) tandem cells, signals a step toward the next generation of space-based energy. 

While gallium arsenide (GaAs) cells currently dominate space applications, their high cost remains a barrier. As demand for LEO communications and space computing surges, crystalline silicon cells and perovskite cells are expected to see rapid adoption. In particular, P-type HJT and perovskite tandem technologies have emerged as the primary focus for the next generation of Space PV. Trina solar is executing a forward-looking strategy in the Space Solar sector. The company’s exploration in this field dates back a decade, when it took the lead in conducting irradiation testing and research on silicon solar cells under space-environment conditions. These early initiatives allowed it to accumulate experimental data and engineering experience, providing a foundation for subsequent technical evolution. 

A research team, led by DGIST (Daegu Gyeongbuk Institute of Science and Technology), recently reported a perovskite-based betavoltaic cell (PBC) incorporating formamidinium lead iodide (FAPbI₃) and carbon-14 nanoparticles, achieving an energy conversion efficiency of 10.79% - which the team claims to be 'unprecedented'.

The work targets applications that require continuous reliable power without external charging, such as artificial intelligence systems, internet of things devices, and space exploration hardware operating in harsh or inaccessible environments.

Researchers from the University of Barcelona, Jaume I University, Slovak University of Technology and University of Valencia have engineered ultrasensitive photodetectors based on inkjet-printed nanocrystalline films of mixed-phase “raisin bread” CsPbBr₃/Cs₄PbBr₆ perovskite integrated onto graphene. By embedding photoactive CsPbBr₃ nanocrystals within a wider-bandgap Cs₄PbBr₆ matrix, the team creates a composite architecture that enhances charge confinement while simultaneously improving environmental stability relative to conventional perovskite films.

The raisin-bread morphology plays a central role in suppressing non-radiative recombination and mitigating degradation pathways that typically limit metal-halide perovskites in photodetector operation. In this configuration, the Cs₄PbBr₆ host passivates the surface of CsPbBr₃ nanodomains and acts as a protective scaffold, helping preserve optoelectronic properties over extended operation under ambient conditions. Coupled with solution-based inkjet deposition, this strategy demonstrates that complex phase-engineered perovskite microstructures can be reproducibly formed over large areas in a maskless, vacuum-free process, supporting low-cost, scalable manufacturing.
