It was reported that Maxwell has signed a full-line supply contract for Perovskite/SHJ tandem cells with a Chinese new energy company, marking its first commercial full-line order in the tandem cell field. This collaboration will enable the client to establish a mass production line for G12H full-size cells.

Maxwell’s full-line tandem cell solution leverages its G12H large-size and full-area technology platform, covering the entire cell manufacturing process. The solution delivers key advantages such as high efficiency, large capacity, intelligence, automation, and cost-effectiveness. It integrates several core technologies, including vacuum technology for high film quality and stability, pre-deposition printing technology that significantly reduces material costs, inkjet printing technology that combines high material utilization with high throughput, and efficient, high-throughput plate-type temporal Atomic Layer Deposition (ALD) technology.

Researchers from the Chinese Academy of Sciences and the University of Science and Technology of China have developed a method to boost upconversion luminescence in oxide perovskites, which tend to display good thermal and chemical stability but limited optical efficiency.

At the core of their approach is a dual-cation substitution strategy applied to titanate perovskites. By precisely adjusting the sodium-to-lithium ratio at the crystal’s A-site, the team induced a controlled structural transition that enhances energy transfer between rare-earth ions, leading to a significant increase in luminescence intensity and quantum yield.

Nippon Sheet Glass (NSG) is targeting perovskite PVs, aiming to position itself as a key materials supplier through the sale of ultra‑thin glass substrates, cover glass, and functional coatings. 

NSG will focus on making substrates for glass and tandem PSCs. 

Verde Technologies has announced that is was chosen as a recipient of the 2026 Leahy Grant through the University of Vermont (UVM) Leahy Institute for Rural Partnerships.

The project, "Empowering Vermont Farms", is a collaborative initiative to study and demonstrate lightweight solar technologies on barns and rural structures that can’t support conventional panels. This project is spearheaded by Verde in partnership with the University of Vermont, the Land care cooperative, von Trapp Family Lodge & Resort, and multiple local farms across Vermont.

Drinda, the parent company of solar cell manufacturer JTPV, has signed a strategic cooperation agreement with satellite solar cell producer Shangyi Optoelectronics. 

As part of the agreement, Drinda will make an equity investment in Shangyi as a strategic shareholder. The 2 parties aim to cooperate on the application of perovskite solar cell technology in space energy systems, covering technology R&D, in-orbit validation, industrialization, and the expansion of application scenarios.

Chinese solar cell equipment manufacturer S.C New Energy has announced that it has successfully delivered its first commercial, mass-production line of flexible perovskite solar cell equipment. The delivered line covers core equipment for key processes, including cleaning, RPD, PVD, and coating.

According to the company, its in-house-developed dedicated RPD equipment enables efficient thin-film deposition at low temperatures, while the slit-coating system ensures uniform coating on flexible substrates. It adds that the VCD vacuum-drying equipment optimizes the crystallization quality of perovskite films.

Chinese display technology leader BOE has announced that it has achieved 4 records in the field of perovskites. According to reports, BOE’s small-area perovskite cell device reached a stabilized efficiency of up to 27.37%. In addition, a 2.88 m² rigid perovskite module produced on its pilot line achieved an output power of 579 W and a full-area efficiency of 20.11%, which the company claims ranks it first in the industry for large-area single-junction perovskite devices.

BOE also reported achieving 21.39% efficiency for flexible perovskite modules on its laboratory line, as well as 16.6% efficiency and 433 W output on its pilot line. The company stated that this represents the industry’s largest-area and highest-power flexible perovskite module to date.

At a recent PV conference, Solarlab Aiko Europe, a Germany-based research unit of Chinese back-contact (BC) module manufacturer Aiko, delivered an update on its perovskite-silicon tandem solar cell research based on two-terminal (2T) and three-terminal (3T) tandem configurations. 

AIKO's latest 2T perovskite-silicon tandem lab-scale cell reportedly achieved a power conversion efficiency of 34.76%. The tandem, which had a heterojunction (HJT) silicon bottom cell, was developed in collaboration with researchers at Aiko headquarters and its state-of-the-art Yiwu R&D line. Interface engineering and material passivation methods were used to reduce efficiency losses and enhance stability. 

UK-based Power Roll has announced a Joint Development Agreement with Germany-headquartered RENOLIT, a global expert in high-quality polymer films. 

Over the next 18 months, RENOLIT will conduct real-world outdoor trials of Power Roll's microgroove solar films at its German facilities, validating performance This marks a step in commercializing Power Roll’s unique solar film that aim to transform rooftops and other surfaces into clean energy generators.

Researchers from AMOLF, the University of Pavia, and the University of Potsdam have introduced a new way to study mobile ions in perovskite solar cells, a factor that strongly influences how these devices age and lose performance. Understanding and controlling such ions is considered crucial for improving the long‑term stability of perovskite technology.

The technique draws inspiration from freezing water: when the device is cooled, the ions effectively “freeze” in place and stop migrating through the material.
Before cooling, the team first drives the ions toward one side of the device with an applied voltage; when the cell is warmed again, the ions “thaw” and drift back, generating a measurable electrical current because of their charge. By analyzing this current, the researchers can determine how many mobile ions are present and how strongly they are bound inside the perovskite layer.
