BIPV

UtmoLight's 6.7 MW perovskite rooftop distributed PV project at Wanshan Lake Park was connected to the grid and put into operation on July 31, completing the project first announced in partnership with Wuxi Xingyuan Green Energy back in November 2025.

The project uses the roof resources of factory buildings in the park, with nearly 15,000 pieces of UtmoLight's own 2.81 m² perovskite PV modules installed. It operates under a "self-generation for self-use, with surplus power fed to the grid" model. 

Researchers from India's Indian Institute of Technology (IIT) Mandi have developed semi-transparent perovskite solar cells (ST-PSCs) based on compositionally tuned MAPbI₂.₆Br₀.₄ films, demonstrating a well-balanced trade-off between transparency and efficiency for building-integrated photovoltaics (BIPVs) and indoor energy harvesting.

The team engineered the perovskite absorber by systematically substituting methylammonium bromide (MABr) with methylammonium iodide (MAI) in MAPbI₃ precursors, while simultaneously varying precursor concentrations from 1 M down to 0.15 M. This dual strategy enabled precise control over both halide composition and film thickness - two key parameters governing optical transmission and photovoltaic performance.

Chinese perovskite PV company Microquanta has introduced a new series of perovskite-silicon tandem modules at a recent exhibition in Germany, targeting building‑integrated PV (BIPV) façade applications.

The new MQ‑α² products combine Microquanta’s four‑terminal perovskite-silicon tandem architecture with architect‑oriented colored finishes designed for façades. According to the company, the tandem structure is intended to compensate for the efficiency losses that typically occur when solar modules are modified for aesthetic purposes, allowing higher energy yields than conventional decorative BIPV panels.

UtmoLight has introduced a new series of solar modules at SNEC 2026 in Shanghai, marking a shift toward application-focused product design rather than purely scaling efficiency and size. The launch includes two distinct modules engineered to tackle durability and deployment challenges that have limited broader adoption of perovskite technology.

The new lineup features the Chuangshi S2, a high-strength module designed for demanding outdoor conditions, and the Chuangshi S1, an ultra-lightweight solution aimed at distributed and building-integrated photovoltaics (BIPV). Together, the products reflect a growing emphasis on tailoring perovskite modules to real-world operating environments.

The EU-funded LUMINOSITY project is advancing the industrialization of flexible perovskite solar cell (PSC) technology, with a strong focus on scalability, sustainability, and real-world deployment. Coordinated by TNO (Netherlands Organization for Applied Scientific Research), the project brings together leading European research institutes, universities, and industrial partners to bridge the gap between laboratory-scale innovation and large-scale manufacturing.

LUMINOSITY - short for “Large area uniform industry compatible perovskite solar cell technology” - aims to enable commercially viable production of flexible perovskite photovoltaics using established industrial processes. Central to this effort is the adoption of roll-to-roll (R2R) manufacturing, targeting module efficiencies above 20% over areas exceeding 900 cm², while advancing the technology readiness level (TRL) to 7.

During a recent industry exhibition, UtmoLight reportedly signed a cooperation agreement with the China Construction Fourth Engineering Division (CSCEC 4th Bureau) for a "19MW Perovskite PV Module Project," marking the transition of perovskite PV technology from demonstration to large-scale application.

In the future, the two parties will use this project as a driving force to create benchmark applications for perovskite modules in scenarios such as large public buildings and high-quality commercial and industrial rooftops.

Japan will launch a government‑led demonstration project to deploy perovskite solar cells at Self‑Defense Forces (SDF) facilities, starting as early as this summer. According to Japanese media reports, the first installations are planned at SDF bases in Okinawa Prefecture, with the aim of creating early, large‑scale demand and accelerating the commercialization of domestic perovskite technologies.

The project will use lightweight, flexible perovskite modules that can be installed on a wide range of surfaces, including roofs and building walls, where conventional silicon panels are difficult to mount. By leveraging the extensive real estate of SDF bases, the government hopes to showcase practical use cases and validate durability, safety and performance in real‑world conditions.

Perovskite manufacturer Renshine Solar is developing what it describes as the ‘world’s largest’ perovskite building-integrated photovoltaic (BIPV) rooftop project.

The installation will use around 6,000 perovskite modules across a 4,000 m² rooftop at the former Shanghai Boiler Factory workshop. The company said its lightweight and flexible modules can be customized in color and size to meet architectural design requirements for BIPV applications.

Korea Electric Power Corporation (KEPCO), Korea's largest state-controlled electric utility, has announced plans to construct the nation's first large-scale commercial facility as a Zero Energy Building (ZEB) with an energy self-sufficiency rate of 100% or higher.

To achieve an energy self-sufficiency rate of 100% or more, KEPCO plans to expand the installation of high-efficiency solar panels and integrate cutting-edge energy technologies into the building. The utility intends to pilot technologies currently under in-house research and development, including perovskite building-integrated photovoltaics (BIPV) using glass window-type panels, ultra-high-efficiency tandem solar cells, and hydrogen fuel cells.

Researchers from Nanyang Technological University (NTU) have demonstrated fully vacuum‑processed ultrathin perovskite solar cells with MAPbI₃ absorber layers down to around 10 nm, achieving multi‑percent efficiency together with high transparency for building‑integrated use.

The team thermally evaporated MAPbI₃ in a planar p–i–n architecture and varied the absorber thickness from about 10 nm to several hundred nanometers. Devices with 10 nm, 30 nm, and 60 nm layers reached power conversion efficiencies of roughly 7%, 11%, and 12%, respectively, with open‑circuit voltage and fill factor remaining comparable to conventional 300–900 nm “bulk” devices, indicating low trap density and good optoelectronic quality.
