Researchers from Stanford University and Mississippi State University recently explored the potential of Mn²⁺-doped perovskite LEDs (PeLEDs) for lighting and display applications. 

By introducing a molecular additive, tris(4-fluorphenyl)phosphine oxide (TFPPO), Mn²⁺-doped PeLEDs achieved a peak external quantum efficiency of 14.0% and peak luminance (i.e., brightness) of 128,000 cd/m². These high efficiencies and brightnesses suggest that Mn²⁺-doped PeLEDs could be implemented in lighting or display applications. However, device stability is also important to consider. The team found that introducing TFPPO compromises the stability of Mn²⁺-doped PeLEDs—a decrease from 37.0 to 2.54 min. By analyzing both the optoelectronic and photophysical characteristics of Mn²⁺-doped PeLEDs before and after device operation, the scientists reported insights into this efficiency-stability trade-off.

Verde Technologies, a perovskite-focused thin-film solar company, has announced a new exclusive partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Northern Illinois University (NIU) to work collaboratively on the commercialization of perovskite solar cells. 

By combining NREL's and NIU’s expertise with Verde's cutting-edge manufacturing techniques, this collaboration aims to unlock the potential of efficient, safe, low-cost perovskite solar panels at an unprecedented scale.

Researchers from China's Harbin Institute of Technology and University of Electronic Science and Technology of China have proposed a facile and universal platform to fabricate integrated spectrometers with solution-processable semiconductors by involving the conjugated mode of the bound states in the continuum (conjugated-BIC) photonics.

Acquiring real-time spectral information in point-of-care diagnosis, internet-of-thing, and other lab-on-chip applications requires spectrometers with hetero-integration capability and miniaturized form. Compared to conventional semiconductors integrated by heteroepitaxy, solution-processable semiconductors provide a much-flexible integration platform due to their solution-processability, and, therefore, more suitable for multi-material integrated systems. However, solution-processable semiconductors are usually incompatible with micro-fabrication processes, making them impractical for use in various applications.

Researchers from China's University of Science and Technology (SUSTech), Chinese Academy of Sciences (CAS), City University of Hong Kong (CityU) and Korea University have developed an effective strategy to modify the Tin dioxide (SnO₂)/perovskite buried interface by passivating the buried defects in perovskite and modulating carrier dynamics via incorporating formamidine oxalate (FOA) in SnO₂ nanoparticles.

Tin dioxide (SnO₂) is a commonly used electron transport material for n-i-p-type perovskite solar cells (PSCs) due to its high light transmittance and electron mobility, suitable energy levels, good stability under UV irradiation, and it can be processed at low temperatures. The buried interface of perovskite/SnO₂ plays a major role in achieving high efficiency and stability. However, the non-exposed buried interface is challenging to study and manipulate.

Researchers from China's Hebei University of Technology and Chinese Academy of Sciences have found that increasing the diameter of single-wall carbon nanotubes (SWCNTs) in SWCNT/perovskite QD heterojunctions can improve the optoelectronic performance of the heterojunction between the two materials.

The team systematically tested the performance effects of varying diameters of SWCNTs, a single layer of carbon atoms that form a hexagonal lattice rolled into a seamless cylinder, with different band gaps, or the amount of energy required for an electron to conduct electric current, in heterojunction films with perovskite QDs. Their study indicated that increasing the diameter of SWCNTs improved the responsivity, detectivity and response time of this type of heterojunction film. This effect may be mediated by the enhanced separation and transport of photogenerated excitons, an energy-carrying, neutrally charged electron that combines with a positive electron hole, in the film.

Reports suggest that REVKOR Energy Holdings, a U.S-based renewable energy company, and H2GEMINI Technology Consulting, a Swiss-German manufacturer of solar machinery and equipment, have formed a partnership to construct turnkey HJT solar cell and module manufacturing facilities and collaborate on the development of new generations of high-efficiency HJT/perovskite solar cell architectures.

Under the terms of the partnership, REVKOR and H2GEMINI will collaborate to establish high-efficiency HJT PV cell and module production across multiple project sites, with a targeted capacity of 20GW by 2026. The first phase of the project will focus on building a 5GW annual production facility, aiming for production to begin by the second quarter of 2024. Subsequently, in Phase Two, the capacity will be expanded to a total of 20GW by the end of 2025. This partnership comes just before the completion of REVKOR's Phase One facility on August 5th, 2023, spanning 1,067,000 Sq Ft in Salt Lake City, will become operational late second quarter 2024, with the HJT/Perovskite 5 GW equipment fully installed, this facility is meant by Revkor (as mentioned on its website) to become the first HJT/perovskite solar cell and panel manufacturing plant in the United States.

Scientists at Singapore's Nanyang Technological University (NTU) have built Three new satellites, that were successfully blasted off into orbit, taking NTU’s total satellite launch count to 13. These satellites (called SCOOB-II, VELOX-AM and ARCADE) will be used to conduct orbital experiments such as testing 3D-printed parts in space, measuring atmospheric data, and evaluating new space materials.

The ARCADE (Atmospheric Coupling and Dynamics Explorer) satellite aims to measure data for atmospheric coupling studies. It carries unique instruments, among which are newly developed flexible perovskite solar cells, which will be used in experiments to test their performance in Low Earth Orbit for potential applications in curved, rollable solar panels.
