					</table><p>A team of researchers led by <a href="https://www.psu.edu/" target="_blank" rel="noopener">Penn State University</a> has created a new process to fabricate large perovskite devices that are more cost and time effective and holds the potential to accelerate future materials discovery.</p>
<p>EM-FAST, also known as spark plasma sintering, involves applying electric current and pressure to powders to create new materials. The process has a 100% yield wherein all the raw ingredients go into the final device, as opposed to 20 to 30% in solution-based processing.</p>
<p>The technique produced perovskite materials at .2 inches per minute, allowing scientists to quickly create large devices that maintained high performance in laboratory tests.</p>
<p>The team reported their findings in the journal <em>Nature Communications</em>.</p>
<p>“This method we developed allows us to easily create very large bulk samples within several minutes, rather than days or weeks using traditional methods,” said Luyao Zheng, a postdoctoral researcher in the Department of Materials Science at Penn State and lead author on the study.</p>
<p><strong>The EM-FAST Technique</strong></p>
<p>The researchers used a sintering method called the electrical and mechanical field-assisted sintering technique (EM-FAST) to create the devices.</p>
<p>Sintering is a commonly used process to compress fine powders into a solid mass of material using heat and pressure.</p>
<p>While these materials have excellent properties, the approach is expensive and inefficient for creating large perovskites and the solvents used may be toxic, the researchers said.</p>
<p>“Our technique is the best of both worlds…we get single-crystal-like properties, and we don’t have to worry about size limitations or any contamination or yield of toxic materials,” said Bed Poudel, a research professor at Penn State and a co-author.</p>
<p>Because it uses dry materials, the EM-FAST technique opens the door to include new dopants, ingredients added to tailor device properties, that are not compatible with the wet chemistry used to make thin films which in turn can potentially accelerate the discovery of new materials.</p>
<p>This opens up possibilities to design and develop new classes of materials, including better thermoelectric and solar materials, as well as X- and γ-ray detectors, the researchers said.</p>
<p>The new process also allows for layered materials — one powder underneath another — to create designer compositions. In the future, manufacturers could design specific devices and then directly print them from dry powders.</p>
<p>While the university scientists have long used EM-FAST to create thermoelectric devices, this work represents the first attempt to create perovskite materials with the technique.</p>
<p>Recently, an international team of researchers <a href="https://mercomindia.com/researchers-improves-with-new-material-layer/" target="_blank" rel="noopener">developed</a> a new technique to enhance the durability of inverted perovskite solar cells, which can be an essential step toward commercializing emerging photovoltaic technology and significantly reducing the cost.</p>
<p>In January, researchers at the Helmholtz-Zentrum Berlin said that they had <a href="https://mercomindia.com/perovskite-cells-retain-efficiency-during-fluctuations/" target="_blank" rel="noopener">produced</a> perovskite solar cells to achieve efficiencies of well above 24%, which are resistant to drop under rapid temperature fluctuations between -60 and +80 degrees Celsius over one hundred cycles.</p>

					</table><p>A team of scientists from Pennsylvania State University (<a href="https://www.psu.edu/" target="_blank" rel="noopener">Penn State</a>) has found that nanoparticles boost the efficiency of solar cells not because of the up-conversion but due to enhanced light scattering.</p>
<p>The scientists said that this light scattering process boosted efficiency in the solar devices they created. Scientists have proposed that tapping into this could push solar cell efficiency past its theoretical ceiling, the Shockley-Queisser (SQ) limit, which is around 30% for single-junction solar cells powered by sunlight.</p>
<p>The usual method involves adding up-conversion nanoparticles to the materials used in the solar devices. Up-conversion materials allow solar cells to harvest energy from a wider spectrum of light than normally possible. Adding nanoparticles is like adding millions of small mirrors inside a solar cell. The light traveling through the device hits the nanoparticles and scatters, potentially hitting other nanoparticles, reflecting many times within the device, and providing a noticeable photocurrent enhancement.</p>
<p>“We were focused initially on up-converting infrared light to the visible spectrum for absorption and energy conversion by perovskite, but the data from our PennState colleagues indicated this was not a significant process. Subsequently, we provided undoped nanocrystals that do not give optical up-conversion, and they were just as effective in enhancing the energy conversion efficiency,” said Jim Piper, co-author and emeritus professor at Macquarie University, Australia.</p>
<p>Adding the nanoparticles boosted the efficiency of perovskite solar cells by 1% in the study, the scientists reported in the journal ACS Energy Letters. Changing the shape, size, and distribution of nanoparticles within these devices could further lead to even more photocurrent enhancement and higher efficiencies.</p>
<p>“It could be the future research direction based on ideas from this research,” said Shashank Priya, associate vice president for research and professor of materials science and engineering at Penn State.</p>
<p>Last month, researchers from Swansea university and Tata Steel, UK, <a href="https://mercomindia.com/new-research-shows-perovskite-solar-panels/" target="_blank" rel="noopener">found</a> that perovskite solar cells could be printed on steel atop buildings.</p>
<p>Earlier, Fraunhofer researchers claimed to have <a href="https://mercomindia.com/fraunhofer-researchers-claim-record-efficiency-four-junction-solar-cell/" target="_blank" rel="noopener">achieved</a> a record efficiency of 47.6% for a four-junction solar cell.</p>
