The plant will mass-produce ultra-large perovskite modules and building-integrated photovoltaic (BIPV) products, and as the line ramps up to full production, it is expected to produce about 1.8 million such modules annually.
Researchers from China's Westlake University, Advanced Solar Technology Institute of Xuancheng and Turkey's Marmara University have addressed the stability issues of perovskite solar cells (PSCs) by developing a divalent cation replacement strategy that mitigates ionic migration while limiting phase segregation.
Using the new method, the scientists fabricated a champion cell that showed a PCE of 23.20% (certified 22.71%) for a single-junction PSC with a bandgap between 1.67 eV and 1.68 eV. Furthermore, a PCE of 30.13% was obtained for mechanically stacked perovskite/Cu(In,Ga)Se2 tandem devices, and a PCE of 21.88% for transparent perovskite devices. Finally, they obtained a steady-state PCE of 23.28% (certified 22.79%) for flexible monolithic perovskite/Cu(In,Ga)Se2 tandem cells.
A Japanese consortium that includes three companies is testing the durability and performance of lightweight, flexible perovskite solar modules at Osanbashi Pier, Yokohama City in windy and salt-air conditions. The outdoor trial is part of a larger 3-year perovskite solar technology research collaboration.

The three-month 1 kW perovskite solar module trial on Osanbashi Pier began in November 2024. The three Japan-based companies that are participating in the outdoor seaport demonstration are: Macnica, a technology and electronics supplier, Reiko, a thin film product manufacturer, and perovskite solar cell specialist Peccell Technologies, which was founded in 2004 as a Toin University of Yokohama spin-off by perovskite solar cell pioneer Tsutomu Miyasaka.
Halide perovskite single crystals have demonstrated enormous potential for next-generation integrated optoelectronic devices. However, there is a lack of
a facile method to realize the controllable growth of large-scale, high-quality, and high-resolution perovskite single crystal arrays on diverse types of
substrates, which hinders their application in practical scenarios.

Now, researchers from the University of Hong Kong, Nankai University and Korea Advanced Institute of Science and Technology (KAIST) have developed a one-step wettability-guided blade coating approach for the rapid in situ crystallization of large-scale, multicolor, and sub-100 nm perovskite single-crystal arrays in ambient conditions.
ART-PV India, an IIT Bombay-incubated start-up, has been awarded a $10 million grant by the Ministry of New and Renewable Energy (MNRE). The funding will enable the company to set up a manufacturing plant for high-efficiency tandem solar cells.
ART-PV has developed a 4T cell with PCE >30% on small area ~1 cm2, which will be transferred to 2T using industry partners supplying semi-processed bottom sub-cells.

Scientists from HZB and Humboldt University Berlin have reported a CIGS-perovskite tandem cell that sets a record with an efficiency of 24.6%, certified by the independent Fraunhofer Institute for Solar Energy Systems.
The team's new tandem solar cell combines a bottom cell made of CIGS with a top cell based on perovskite. By improving the contact layers between the top and bottom cells, they were able to increase the efficiency to 24.6%. This cell was the result of a successful team effort: the top cell was fabricated by TU Berlin master's student Thede Mehlhop under the supervision of Stefan Gall. The perovskite absorber layer was produced in the joint laboratory of HZB and Humboldt University of Berlin. The CIGS sub-cell and contact layers were fabricated by HZB researcher Guillermo Farias Basulto. He also used the high-performance cluster system KOALA, which enables the deposition of perovskites and contact layers in vacuum at HZB.
Researchers from China's Northwest Normal University, Xidian University and Xi'an Shiyou University have developed a four-terminal perovskite-CIGS tandem solar cell based on a top semi-transparent perovskite device with an efficiency of 21.26% and a high bifaciality factor of 92.2%. The scientists used a solvent-annealing strategy to produce a perovskite film with full coverage, larger grains, superior crystallinity and free of detectable lead iodide impurity.
The team fabricated a four-terminal (4T) tandem solar cell based on a top semi-transparent perovskite device and a bottom cell relying on copper-indium-gallium-selenide (CIGS). The scientists used a stepwise dimethyl sulfoxide (DMSO) solvent-annealing method to improve the crystallinity of the perovskite film used in the perovskite top cell and fabricated films with a wide bandgap of 1.68 eV via two consecutive heating steps: annealing at 100 C and then 80 C.
Researchers from the University of Cambridge, Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a novel way to make hydrocarbons – powered solely by the sun.

The device they developed combines a light absorbing ‘leaf’ made from a perovskite solar cell, with a copper nanoflower catalyst, to convert carbon dioxide into useful molecules. Unlike most metal catalysts, which can only convert CO₂ into single-carbon molecules, the copper flowers enable the formation of more complex hydrocarbons with two carbon atoms, such as ethane and ethylene — key building blocks for liquid fuels, chemicals and plastics.
Researchers from Japan's Ritsumeikan University and Sekisui Chemical have studied the role of barrier films in shielding flexible perovskite solar modules from harsh environmental conditions.
The research team utilized PSC modules made of methylammonium lead iodide (MAPbI₃), which were encapsulated with polyethylene terephthalate substrate with barrier films of varying water vapor transmission rates (WVTR). The PSC modules were subjected to a damp heat test, which utilized exposure of the modules to 85 °C temperature and 85% relative humidity. The conditions were set to simulate real-world outdoor conditions over extended periods.
