These easily synthesized materials are considered the future of solar cells, as their distinctive structure makes them perfect for enabling low-cost, efficient photovoltaics. They are also predicted to play a role in next-gen electric vehicle batteries, sensors, lasers and much more. Recent Perovskite News Researchers examine the benefits of down-conversion materials for perovskite solar cells An international group of researchers from Swansea University, Indian Institute of Technology, University of Jammu, CSIR and Khalifa University of Science and Technology recently examined how down-conversion (DC) materials could be used to improve the performance of solar cells based on perovskite materials. The team reported that such materials could result in an electric yield enlargement by converting ultraviolet (UV) light to visible, while also providing UV shielding. Image “The DC materials can absorb the high-energy photon (300–500 nm) and re-emit a longer-wavelength photon to which the photovoltaic (PV) device is more sensitive,” the team said. “Various types of DC materials have been investigated for this purpose like quantum dots (QDs), oxides, luminescent glasses, lanthanides, and organic dyes.” Read the full story Posted: Jun 26,2022 Perovskite-based electronics can program and reprogram computer hardware on demand through electrical pulses A multi-institutional team, including the U.S. Department of Energy’s (DoE) Argonne National Laboratory, has developed a perovskite-based approach with which computer chips can be designed to learn to reconfigure their circuits when presented with new information. It does so by mimicking functions in the human brain with so-called “neuromorphic” circuits and computer architecture. “Human brains can actually change as a result of learning new things,” said Subramanian Sankaranarayanan, a paper co-author with a joint appointment at Argonne and the University of Illinois Chicago. “We have now created a device for machines to reconfigure their circuits in a brain-like way.” Read the full story Posted: Jun 24,2022 Researchers integrate large-area graphene-perovskite solar panels into stand-alone solar farm An international research group, including teams from CHOSE at the University of Rome Tor Vergata, Hellenic Mediterranean University in Greece and others, has developed a large-area perovskite solar panel with graphene-doped electron transporting layers (ETLs) and functionalized molybdenum disulfide (fMoS2) buffer layers inserted between the perovskite layer and the hole transporting layer (HTL). Image The team reported that with increasing temperatures, the module exhibited a smaller drop in open-circuit voltage than commercially available crystalline silicon panels.

It was applied to 25,720 scientific articles comprising 660,881 data entries representing 57,678 photovoltaic devices. The database for the dye-sensitized devices included 475,045 entries organized into 41,680 records. The one for perovskite cells included 185,836 entries organized into 15,818 records.

This performance is said to be a world record for flexible perovskite modules over 10 cm2. Image Perovskite-based modules before and after flexible encapsulation. Image credit: CEAFor some applications, the use of flexible substrates may be attractive for single-junction perovskite technology as it opens the way to high-speed, low-temperature printing processes. Thus, it becomes possible to use low cost substrates whereas inorganic flexible technologies, such as CIGS, require higher temperature processes and substrates that are more expensive. Many teams around the world are trying to meet the challenges of making larger area devices with sufficient stability for real-life applications. This is one of the tasks standing before partners of the European APOLO project, as part of which these results were obtained.

Image The team tested GABr in mixed solvents combining isopropyl alcohol (IPA) and toluene (TL), which they said can efficiently passivate interface and grain boundary defects by minimizing the IPA solubility of the perovskite surface. They compared the mixing of IPA with ethyl acetate (EA), chlorobenzene (CB), and toluene (TL) to dissolve GABr, and further optimized the concentration of GABr and the mixing ratio of the two solvents.

Finding that illusive mathematical value would be a major advancement in opening new options for simulations involving quantum materials.Many scientific questions depend heavily on being able to find that mathematical value, said Wei Bao, Nebraska assistant professor of electrical and computer engineering. The search can be challenging even for modern computers, especially when the dimensions of the parameters — commonly used in quantum physics — are extremely large. Until now, researchers could only do this with polariton optimization devices at extremely low temperatures, close to about minus 270 degrees Celsius. Bao said the Nebraska-UC Berkeley team “has found a way to combine the advantages of light and matter at room temperature suitable for this great optimization challenge.” Read the full story Posted: Jun 18,2022 Researchers develop novel accelerated aging testing method and a perovskite solar cell with a commercially viable lifetime Researchers from Princeton University in the U.S and Sweden's Linköping University have reported the development of "the first perovskite solar cell with a commercially viable lifetime". The team estimates their device can perform above industry standards for around 30 years, far more than the 20 years used as a threshold for viability for solar cells.Not only is the device said to be highly durable, but it also meets common efficiency standards. It is the first of its kind to rival the performance of silicon-based cells, which have been market leaders for decades.
