The accelerating #technological #advancement of #solarmodules risks exacerbating the challenges of #durability and cell #degradation, according to a new review from the National Renewable Energy Laboratory, which examined the reliability implications of emerging trends in #crystalline-#silicon #photovoltaic #module design. https://lnkd.in/g9r7eBxN

#Perovskite #solarcells (PSCs) are promising next-generation solar #photovoltaic (#PV) cells with high performance and low production costs compared to silicon. However, one of the primary challenges to widespread adoption of PSCs is stability and durability. New research funded by the U.S. Department of Energy (#DOE) examines degradation mechanisms of PSCs under the unfiltered sunlight of the outdoors in comparison with widely used light-emitting diodes. The research, titled “Strong-Bonding Hole-Transport Layers Reduce Ultraviolet Degradation of Perovskite Solar Cells,” was recently published in Science and found that a special #hybrid polymer material synthesised as part of this work and placed within the perovskite cell helped retain high efficiency and improved ultraviolet (#UV) stability in outdoor testing. The cross-country team of researchers for this study was led by the University of #NorthCarolina at Chapel Hill with support from the #Colorado School of Mines; National Renewable Energy Laboratory (#NREL); University of #California, #SanDiego; and University of #Toledo. A key component of this research was an independent verification of the results by DOE’s Perovskite PV Accelerator for Commercialising Technologies (PACT) center. Identifying Reasons for Perovskite Durability Between the Lab and the Outdoors Most PSC testing occurs in the controlled environment of the lab using light-emitting diodes as light sources. To expedite PSC commercialisation, real-world outdoor performance testing is needed to understand underlying mechanisms of sunlight and temperature degradation. Outdoor conditions are different from indoor light-soaking or maximum power point tracking in several ways. Temperature, irradiance, and UV light intensity constantly change outdoors. Perovskite thin-films can decompose when they react with moisture and oxygen or when they spend extended time exposed to light, heat, or applied voltage.

In perovskite solar cells, an electric field separates and drives the electron-hole pairs generated from sunlight shining on the device out of the absorbing semiconductor material to generate electricity. The transport layer collects and moves electrons or holes from the perovskite layer to the electrodes, allowing for the flow of electricity.

Happy to inform you that one of my research paper is accepted and published in Renewable Energy Focus, Journal. This study presents a new hybrid islanding detection method (IDM) designed to improve the islanding detection efficiency of hybrid MGs. The proposed hybrid IDM combines the strengths of two existing islanding detection approaches: The Rate of Change of Phase Angle Difference (ROCPAD) and the Intermittent-Bilateral Reactive Power Variation (IB-RPV). By combining these two techniques, the hybrid strategy uses their complementary qualities, minimizing the drawbacks of each method and improving detection accuracy overall. With analyzed performance, the suggested hybrid IDM’s compatibility with IEEE 1547 standards shows it complies with industry standards. Comparative performance analysis of the proposed IDM with existing IDM shows improved islanding detection accuracy, fast detection of islanding events, and no nuisance tripping. The method is noteworthy for its zero non-detection zone (NDZ) and negligible impact on power quality. The proposed hybrid IDM suits Hybrid Microgrids (HMG) with inverter-based Distributed Generation (DG). https://lnkd.in/dt7ciqiG

Scientists have achieved a record-breaking level of efficiency for flexible solar panels using the so-called ‘miracle material’ perovskite. The lightweight solar panels, developed by researchers in Australia and the UK, were able to convert 11 per cent of the Sun’s energy into electricity, making them suitable for commercial use. Their flexibility means they can also be deployed in previously impossible ways, such as on curved roofs, awnings or even vehicles. Dr Doojin Vak holds up a roll of flexible printed solar cells that use the ‘miracle material’ perovskite (CSIRO) The international team – made up of scientists from the University of Cambridge, Monash University, the University of Sydney and the University of New South Wales – made the breakthrough using a new technique to print the solar cells on bendy rolls. The Commonwealth Scientific and Industrial Research Organisation (CSIRO), an Australian government agency who led the research project, said both the scale and the efficiency achieved during the tests made it a “real game changer” for the renewable energy industry. “The cells are printed using a roll-to-roll technique similar to newspaper printing, which allows for continuous, large-scale production,” the organisation said in a statement. “The dramatic increase in efficiency has paved the way for commercially-viable perovskite solar cell manufacture at scale.” Perovskite has been widely hailed for its potential to vastly increase the efficiency of solar panels, offering a theoretical limit of 43 per cent when combined with silicon compared to just 29 per cent for conventional silicon (PV) solar cells. Last November, researchers in China broke the efficiency record for solar panel electricity generation using a silicon-perovskite tandem solar cell, reaching 33.9 per cent efficiency under lab conditions. Despite being a long way off this record, the 11 per cent achieved in the latest tests is far greater than the efficiency levels of around one or two per cent that printed flexible solar panels currently offer. The next challenge is to scale them up for mass production, with the researchers saying they could be used in everything from disaster relief to space exploration.

25% of global energy consumption powers some of the hardest-to-decarbonize sectors, such as steel smelting and cement production. Today, using solar energy to reach the scorching temperatures needed to power a steel furnace is costly and inefficient. However, scientists at ETH Zurich in Switzerland have developed a new method to use solar thermal trapping to reach temperatures of 1,000 °C - making solar energy a viable option for carbon-intensive industrial processes. While still a proof of concept, the potential is clear. “Solar energy is readily available, and the technology is already here. To really motivate industry adoption, we need to demonstrate the economic viability and advantages of this technology at scale,” said Emiliano Casati, co-author of the study.
