“Researchers claim achievement of new record photovoltaic conversion efficiencies for perovskite-based solar cells by spicing them up with a little capsaicin,” writes Slashdot reader ffkom, adding: “Of course everyone who loves to eat chilis already knew capsaicin energizes you to record levels.” The researchers have published their findings in the journal Joule. From the report: Perovskite solar cells (PSCs) suffer from…

Scientists Just Set a New World Record In Solar Cell Efficiency
According to a paper published in the journal Science, researchers report they they have now hit an efficiency of 29.15 percent in the perovskite/silicon tandem solar cell category. ScienceAlert reports: For this type of panel, the long-term target of more than 30 percent is now tantalizingly within reach. The latest lab tests edge ahead of the maximum 28 percent efficiency that…
A Group of Materials Called Perovskites Could Be a Game-Changer For Solar Power
Researchers from Australia have discovered that the widely acclaimed mineral perovskite can be used to transform the solar industry through cheaper and more efficient photovoltaics. The Independent reports: Perovskite, which is forged deep within the Earth’s mantle, has been hailed for its unprecedented potential to convert sunlight into electricity. Researchers have already improved its sunlight-to-energy efficiency from around 3 per cent…
Aberrant electronic and structural alterations in pressure-tuned perovskite
The perovskite NaOsO3 has a complicated but interesting temperature-dependent metal-insulator transition (MIT). A team led by Drs. Raimundas Sereika and Yang Ding from the Center for High Pressure Science and Technology Advanced Research (HPSTAR) showed that the insulating ground state in NaOsO3 can be preserved up to at least 35 GPa with a sluggish MIT reduction from 410 K to a…
Submerged in water, this new device uses sunlight to produce energy
“The concept is broadly similar to an artificial leaf,” researchers said. Source: https://earthsky.org/human-world/solar-energy-via-water-splitting-module-artificial-leaf…
‘Artificial Leaf’ Concept Inspires Research Into Solar-Powered Fuel Production
Researchers from Rice University have created an efficient, low-cost device that splits water to produce hydrogen fuel. “The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity,” reports Phys.Org. “The current flows to the catalysts that turn water into hydrogen and…
Spin on perovskite research advances potential for quantum computing
The next generation of information technology could take advantage of spintronics—electronics that use the minuscule magnetic fields emanating from spinning electrons as well as the electric charges of the electrons themselves—for faster, smaller electronic devices that use less energy. …
