Flexible thinking on silicon solar cells for wearable electronics or flexible robot skin

Flexible thinking on silicon solar cells from KAUST Video on Vimeo. Combining silicon with a highly elastic polymer backing produces solar cells that have record-breaking stretchability and high efficiency. © 2019 KAUST Crystalline silicon solar panels could be just as effective when incorporated into stretchy wearable electronics or flexible robot skin as they are when used as rigid rooftop panels.

In breakthrough method of creating solar material, scientists prove the impossible really isn’t

Scientists at the National Renewable Energy Laboratory (NREL) achieved a technological breakthrough for solar cells previously thought impossible. The scientists successfully integrated an aluminum source into their hydride vapor phase epitaxy (HVPE) reactor, then demonstrated the growth of the semiconductors aluminum indium phosphide (AlInP) and aluminum gallium indium phosphide (AlGaInP) for the first time by this technique. “There’s a decent

New method to remove dust on solar panels

Taking a cue from the self-cleaning properties of the lotus leaf, researchers at Ben-Gurion University of the Negev have shed new light on microscopic forces and mechanisms that can be optimized to remove dust from solar panels to maintain efficiency and light absorption. The new technique removed 98% of dust particles. In a new study published in ACS Langmuir, the researchers

Scratching the surface of perovskites: Defects in next generation solar devices

Versatile compounds called perovskites are valued for their application in next generation solar energy technologies. Despite their efficiency and relative cheapness, perovskite devices have yet to be perfected; they often contain atomic-level structural defects. Professor Yabing Qi and his team in the Energy Materials and Surface Sciences Unit at OIST, in collaboration with researchers at the University of Pittsburgh, USA,

‘Messy’ production of perovskite material increases solar cell efficiency

Scientists at the University of Cambridge studying perovskite materials for next-generation solar cells and flexible LEDs have discovered that they can be more efficient when their chemical compositions are less ordered, vastly simplifying production processes and lowering cost. The surprising findings, published in Nature Photonics, are the result of a collaborative project, led by Dr Felix Deschler and Dr Sam Stranks.

Researchers to demonstrate first rechargeable lithium-carbon dioxide battery prototype

Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. However, until now, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy. Researchers at the University of Illinois at Chicago are the first to

Physicists to Shine Light on Properties of Potential Solar Cell Material

Research led by University of Texas at Dallas physicists has altered the understanding of the fundamental properties of perovskite crystals, a class of materials with great potential as solar cells and light emitters. Published in July in Nature Communications, the study presents evidence that questions existing models of the behavior of perovskites on the quantum level. “Our enhanced understanding of the physics of
