The team leveraged ground-state electron transfer to develop water-based conductive ink for use in flexible electronics.

A major trend in electronics has been the emergence of flexible electronics in devices such as solar cells and energy storage. The technology enabling these devices to be flexible and lightweight is organic electronics. However, concerns about the sustainability of producing organic electronics are growing.

Recently, researchers in Sweden tackled the sustainability challenges head-on by developing water-based conductive inks in organic electronics.

A new satellite system from Kreios Space only needs air and solar energy for propulsion while improving satellite image resolution 16 fold.

If realized using solar energy or other renewable energy, water splitting could be a promising way of sustainably producing hydrogen (H₂) on a large-scale. Most photoelectrochemical water splitting systems proposed so far, however, have been found to be either inefficient, unstable, or difficult to implement on a large-scale.

Researchers at Ulsan National Institute of Science and Technology (UNIST) recently set out to develop a scalable and efficient photoelectrochemical (PEC) system to produce green hydrogen. Their proposed system, outlined in Nature Energy, is based on an innovative formamidinium lead triiodide (FAPbI₃) perovskite-based photoanode, encapsulated by an Ni foil/NiFeOOH electrocatalyst.

“Our group has thoroughly studied the challenges associated with practical solar hydrogen production,” Jae Sung Lee, Professor of Energy & Chemical Engineering at UNIST and co-author of the paper, told Tech Xplore. “As summarized in our most recent review paper, minimum 10% of solar-to-hydrogen (STH) efficiency is required to develop viable practical PEC system, for which selecting an efficient material is the first criteria.”

Meet PairTree – a solar-powered canopy that charges EVs off-grid – that’s made by US-based solar charging infrastructure manufacturer Paired Power.

PairTree, which started to roll out commercially late last year, is quick and easy to set up – it takes only about four hours – and its ballasted steel foundation fits right into a regular parking space. What sets it apart is its use of bifacial solar panels. These 4.6 kW units increase energy yield by up to 15% compared to traditional panels. This means that in practice, a PairTree unit’s performance rivals that of a 5.3 kW solar array.

PairTree features a UL 9450-listed lithium iron phosphate battery energy storage system, offering a spectrum of daily ranges from 75 to 230 miles, depending on the capacity chosen. It can support either one or two Level 2 EV chargers.

With a 400-mile range and solar capabilities, Aptera’s solar EVs are setting the stage for sustainability and accessibility.

The researchers claim to have achieved 18 percent energy conversion efficiency, trumping all previous achievements, with just a small change.

Researchers at UNIST have used an innovative method to improve the energy efficiency of organic QD solar cells to 18 percent. Previously, it had peaked at 13 percent.

In a significant advancement for next-generation semiconductors, a collaborative research team has made groundbreaking discoveries in the field of two-dimensional (2D) semiconductors.

Their findings, published in Nano Letters, shed light on the generation and control of trions, providing valuable insights into the optical properties of these materials.

2D semiconductors, known for their exceptional light characteristics per unit volume with high flexibility due to their atomic layer thickness, hold immense potential for applications in areas such as advanced flexible devices, nano photonics, and solar cells.

A pivotal achievement has been reached in the realm of energy transition with the development of a cutting-edge tandem solar panel. Interestingly, the solar panel has demonstrated an impressive conversion efficiency rate of 25 percent.

The 25 percent efficiency is a significant improvement above the average 24 percent efficiency found in commercial modules. This makes it the world’s most efficient perovskite silicon tandem solar module in an industrial configuration, as per the release.

This remarkable achievement marks a crucial milestone in the global transition towards sustainable energy sources.

Oxford PV, a spin-off from the University of Oxford, says it’s achieved the world record for the most efficient solar panel.

In collaboration with Germany’s Fraunhofer Institute for Solar Energy Systems, the company says its solar panel achieved 25% conversion efficiency – the percentage of solar energy shining on a panel converted into electricity. That’s a big deal compared to the more typical 16–24% in commercial solar panels.

Oxford PV’s secret sauce is perovskite-on-silicon tandem solar cells, which could theoretically hit over 43% efficiency, leaving traditional silicon solar cells with a theoretical limit of less than 30% in the dust. Its record-setting panel cranked out 421 watts over an area of 1.68 square meters. The researchers used standard mass production gear and optimized it for the tandem technology.
