Dasun Solar has announced that its Anji Intelligent Manufacturing Base project is nearing completion and will soon be operational. 

According to reports, Dasun Solar's Anji intelligent manufacturing project plans to construct 4.8GW of high-efficiency HJT (heterojunction) cell and 7.2GW of fully automated intelligent module production lines. The project will be built in two phases, utilizing fully automated intelligent photovoltaic production equipment to meet the requirements for various advanced processes and technologies. The total investment is 4.7 billion RMB (over USD$650 million).

India's IITB, in collaboration with ART-PV, has developed a lab-scale 4T silicon - perovskite tandem solar cell with an efficiency of up to 30%.

The reported tandem cell follows a 4-terminal (4T) configuration, where the perovskite and silicon layers are stacked non-monolithically, allowing independent optimization of each sub-cell. Notably, the device has demonstrated operational stability with a lifespan of up to 10 years.

Researchers at The Hong Kong Polytechnic University (PolyU) recently announced a novel bilayer interface passivation strategy to develop tandem solar cells that achieved a record-high PCE of 33.89%.

Interfacial recombination at the perovskite/electron transport layer interface has long been considered a major obstacle to enhancing the efficiency of perovskite/silicon tandem solar cells. Prof. YIN Jun, Assistant Professor of the Department of Applied Physics at PolyU, and his research team recently made a breakthrough in interface engineering towards addressing this critical challenge. They integrated advanced material design and a device optimization strategy to develop high-efficiency perovskite/silicon tandem devices. This research was conducted in partnership with LONGI Green Energy Technology and Soochow University. 

Researchers from the Indian Institute of Technology Kharagpur and Indian Institute of Technology Delhi have explained that while perovskite solar cells (PSCs) based on formamidinium (FA) and cesium (Cs) have shown improved thermal stability, their stability under humid conditions remains a significant challenge. 

In their recent study, a two-step protection of perovskite device via utilizing tetraoctylammonium bromide (TOAB) as a surface treatment agent and TOP-3 as a hole-transporting layer has been employed to resist unfavorable device degradation agents. 

Researchers from the University of Science and Technology of China have developed a novel strategy for information encryption/decryption based on stimuli-responsive luminescence of 2D hybrid organic–inorganic perovskites via organic-cation engineering.

The 2D hybrid organic–inorganic metal-halide perovskites' structure consists of inorganic layers formed from lead and iodide ions (linked PbI₆ octahedra) with organic cations arranged between them. They are easy to produce, inexpensive, and printable, while demonstrating interesting optoelectronic properties.

Researchers from King Abdullah University of Science and Technology (KAUST) and the University of Oxford have reviewed interface engineering strategies towards stable perovskite/silicon tandem photovoltaics.

The review specifically explores the critical role of interface engineering in overcoming stability challenges. It highlights the most pressing issues in interface stability, reviews the latest developments in materials and processing strategies to improve interface performance, and outlines the steps needed to bring perovskite/Si tandem solar cells to the commercial market. 

TNO, the Brabant Development Agency (BOM), and Japan’s Sekisui Solar Film Co. have signed a letter of intent in Osaka to explore the establishment of a factory for flexible perovskite solar modules in the Dutch province Brabant.

This could mark a milestone in the journey toward large-scale production of perovskite solar technology. The recent statement said that "Beyond accelerating the energy transition, this initiative strengthens Europe’s energy independence and positions the Netherlands at the forefront of the European solar industry—delivering long-term economic and strategic value".

Researchers from China's Southeast University and Beijing Information Science and Technology University have explained that charge transport layers play a big role in facilitating the extraction and injection of carriers in perovskite solar cells (PSCs), but the performance of PSCs fabricated with conventional charge transport materials tends to exhibit significant hysteresis and instability. 

To address this issue, the team used the composite TiO₂/SnO₂ with superior electron mobility and stability and the low-cost CuSCN as bilayer electron transport layer (ETL) and hole transport layer (HTL) materials, respectively. The PSCs with the p-n-n (p-type FA_xMA_1-xPbI_xBryCl_3-x-y (FA=CH(NH₂)₂), MA=CH₃NH₃)-n-type SnO₂-n-type TiO₂) construction of FTO/TiO₂/SnO₂/FA_xMA_1-xPbI_xBryCl_3-x-y/CuSCN/C/FTO have been investigated via computation simulation and experiment. It was observed that the performance of PSCs with p-n-n structure surpassed that of n-n-p (n-type SnO₂-n-type TiO₂-p-type FA_xMA_1-xPbI_xBryCl_3-x-y) structure, benefiting from the existence of the bilayer ETL with p-n-n structure, which improves the collection ability, and the lifetime and mobility of photogenerated carriers. 

Researchers from Lukasiewicz Research Network - PORT Polish Center for Technology Development, CINTRA (CNRS-International-NTU-THALES Research Alliance), Universitas Indonesia, Nicolaus Copernicus University in Torun and Institut Lumiere Matiere UMR 5306 CNRS have scaled up a new type of light-emitting material - known as a scintillator - by  embedding it with nano-engineered metallic structures, unlocking performance  previously thought unattainable in bulk materials.

Scintillators are special substances that emit visible light when exposed to  high-energy radiation like X-rays or gamma rays. They are critical in numerous fields, from medical imaging and security screening to high-energy physics experiments. But traditional scintillators have limitations: they often emit weak signals or respond slowly, making them less efficient for demanding applications. Nanoplasmonics - a field that manipulates the behavior of light on the  nanoscale using tiny metallic structures - could address this.
