New atomic lift-off technique to promote industrial-scale production of electronic thin films

Researchers from MIT, University of Wisconsin-Madison, Rensselaer Polytechnic Institute, University of Louisville, University of Illinois Urbana−Champaign, Yonsei University and Seoul National University have developed a technique for peeling ultra-thin crystalline electronic membranes away from their substrates to facilitate the high-throughput production of scalable, ultrathin, freestanding perovskite systems. The team used thin film membranes developed in their experiments to create a record-breaking infrared-detecting sensor that could be used in night vision eyewear or autonomous vehicles.

Study author Chang-Beom Eom, a professor of materials science and engineering at the University of Wisconsin-Madison, is an expert in crystalline perovskite oxides, containing oxygen and, typically, transition metals in a distinct atomic arrangement. These materials are particularly stable and strong when produced as thin films and can be precisely engineered at the atomic level. They also offer a wide range of tunable functions, including superconductivity, oxygen catalysis, magnetoresistance, and insulating behaviors. If incorporated into next-generation devices, these films could lead to a whole range of new gadgets, including improved fuel cells, field-effect transistors, spintronic-based memory devices and a wide range of detectors.

Qcells achieves key tandem solar module stability milestone

Qcells has announced it has achieved successful stress test validation for its tandem modules, according to both IEC and UL certification standards. These tests also complied with tandem-specific requirements for power measurements, it was reported. The standard-compliant execution of the stress tests and measurements has been independently confirmed by TÜV Rheinland. 

By successfully passing the most critical stress tests for solar cell reliability, especially considering tandem-specific restrictions on power measurement, Qcells has demonstrated that tandem technology can now meet the performance benchmarks that set the groundwork for commercial acceptance.

2D perovskite layered onto a 3D perovskite could enable efficient and stable perovskite solar cells

Researchers from Cornell University, Duke University and Brookhaven National Laboratory have designed a two-dimensional (2D) perovskite that can be layered on top of a 3D perovskite to act as a rugged, weather-resistant coating. By finding the atomic equivalent of a perfect handshake between two types of perovskites, the researchers were able to build solar cells that are not only high-performing, but exceptionally durable.

Other researchers have attempted this protective 2D perovskite coating using methylammonium (MA) as a cage cation. However, MA is so unstable it starts to vaporize upon exposure to sunlight. “With MA, you have good efficiency and charge transport, but the solar cell degrades rapidly in a few hundred hours of continuous operation, ” said lead author Shripathi Ramakrishnan, a doctoral candidate in the lab of senior author Qiuming Yu, professor of chemical and biomolecular engineering at Cornell Engineering.

Halocell Energy partners with AIBN to advance tin-based perovskite solar panels

The University of Queensland (UQ) and Halocell Energy have announced they will be working together to advance tin-based perovskite solar panels.

UQ's Australian Institute for Bioengineering and Nanotechnology (AIBN) researcher Dr. Peng Chen has secured almost $200,000 through the latest Australia’s Economic Accelerator Ignite funding round to accelerate the commercial production of tin-based perovskite solar panels. Dr. Chen and his team - including UQ’s Professor Lianzhou Wang and AIBN’s Dr Dongxu He – have replaced the lead with tin, recently setting a world-record efficiency for lead-free perovskite solar cells. Now, Halocell Energy and UQ have decided to take the project to the next phase and scale up for real world use in lead-free solar panels.

New synergistic doping strategy could enable more efficient and stable perovskite solar cells

Researchers from China's Westlake University, Fudan University and Zhejiang University have explained that while record power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) are usually achieved using organic spiro-OMeTAD, conventional doping with hygroscopic dopants (LiTFSI and tBP) leads to compromised device stability.

In their recent work, the team introduced a synergistic mixed doping strategy that utilizes a combination of metal-TFSI dopants—LiTFSI, KTFSI, NaTFSI, Ca(TFSI)2, and Mg(TFSI)2—to enhance doping efficiency while effectively removing hygroscopic contaminants from the Spiro-OMeTAD solution. This approach enables PCEs exceeding 25% and significantly improved stability under harsh environmental conditions.

A single perovskite photodiode enables full-color pixel

Researchers from Soochow University and Yangzhou University have developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, and machine learning algorithms.

While conventional photodetectors are able to measure how much light is present, they typically can't identify what kind of light it is. Extracting color or spectral information usually requires added hardware—filters, lens stacks, or multiple detectors arranged side by side or layered vertically. These systems tend to be bulky, expensive, and hard to scale, particularly when designing small, low-power devices. Even more recent strategies, like using heat or voltage to modulate a detector’s response, introduce other trade-offs, such as slower operation and higher instability.

Fraunhofer ISE develops contactless method for measuring the performance of back-contact solar cells

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have developed a contactless method for measuring the performance of back-contact solar cells in the production line. 

Measuring the current-voltage characteristic curve is the most important test in solar cell quality control. Eliminating physical contact with the solar cell saves time and thus allows significantly higher throughput rates in production. It also eliminates mechanical stress on the solar cells during measurement and reduces the maintenance costs of the measuring system. The researchers tested the method for the first time in 2022 and have now successfully transferred it to IBC (interdigitated back contact) cell architectures in a production-related environment.

New molecular polymerization strategy could combat lead leakage and improve the stability of PSCs

Identifying lead leakage and stability as major challenges for the commercialization of perovskite solar cells (PSCs), researchers from Chongqing University and Huazhong University of Science and Technology have developed a polymerization method to achieve highly stable and environmentally friendly high-performance PSCs.

Through the addition of the small organic molecule N,N′-bis(acryloyl)cystamine (BAC) to the perovskite precursor solution, the terminal alkenes of BAC enable the construction of polymer BAC (PBAC) at the perovskite grain boundaries (GBs) during the annealing process of the perovskite films. PBAC not only overcomes the limitations of organic small molecules but also interacts with perovskites through its numerous functional groups and multiple reactive sites. This interaction effectively passivates deep-level defects, suppressing nonradiative carrier recombination.
