Researchers from the Chinese Academy of Sciences (CAS) and Sichuan University have developed an innovative seed-assisted epitaxial growth strategy to stabilize and enhance the photoactive α-phase in perovskite solar cells (PSCs). By introducing pre-synthesized (GABA)₂PbI₄ single crystals (GABA = Gamma-aminobutyric acid) into the 3D perovskite precursor solution, the team achieved preferential and rapid formation of the black α-FAPbI₃ phase at room temperature.

In situ grazing-incidence wide-angle X-ray scattering (GIWAXS) analyses revealed that these (GABA)₂PbI₄ seeds serve as epitaxial templates, accelerating α-phase crystallization while suppressing the formation of the undesired δ-phase. The key lies in the highly matched lattice constants between the seeds and α-FAPbI₃, which reduce the nucleation barrier and guide the film’s vertical orientation.

After a highly successful event last year, Perovskite Connect returns to Berlin on 21–22 October 2026. Join us again in 2026 - as a speaker, exhibitor, or attendee - and help define the future of perovskite technology!

Building on the energy and insight of Perovskite Connect 2025, this year’s conference and exhibition will once again bring together global innovators, researchers, and industry leaders advancing perovskite commercialization. The 2025 edition drew outstanding feedback from across the ecosystem, here are some of their impressions:

Australian advanced materials company Lava Blue has signed a memorandum of understanding (MoU) with solar technology developer HaloCell Energy to establish a domestic supply chain for high-purity perovskite precursor materials. The partnership aims to address cost and availability challenges that have constrained the commercial deployment of next-generation PV technologies.

The non-binding agreement positions Lava Blue to supply specialty chemicals derived from local feedstocks, including mine tailings, to support HaloCell’s commercial-scale roll-to-roll manufacturing of perovskite solar modules designed for drones, satellites, and low-light energy-harvesting applications.

A team of researchers, which was led by Seoul National University and included teams from SN Display, Imperial College London, University of Cambridge, Hanyang University, KAIST, University of Tennessee, Universidad de Valencia, and PEROLED, has demonstrated a hierarchical-shell perovskite platform that platform that delivers near-unity efficiency together with commercial-grade stability and full display-scale manufacturability. The team stated that this work could pave the way for next-generation vivid-color display technologies.

The researchers developed a hierarchical-shell architecture that chemically interlocks perovskite nanocrystals with inter-bonded PbSO₄, SiO₂, and polymer layers, suppressing lattice softening, ion migration, and interfacial degradation that previously limited stability. This design enabled solid-state perovskite nanocrystal films to reach a photoluminescence quantum yield of 100% and an external quantum yield of 91.4%, the highest reported among solid-state emitters such as phosphors, organic emitters, quantum dots, and other halide perovskites. Because the emitters retain intrinsically narrow linewidths of about 20 nm, they can satisfy and even exceed the Rec. 2020 color standard, allowing more vivid, lifelike colors than typical OLED and quantum-dot displays.

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.

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.
