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

Solar Cells With New Interfaces: Innovative Two-Dimensional Materials Increase the Efficiency of perovskite solar cell above 20%

Scientists from NUST MISIS (Russia) and University of Rome Tor Vergata found out that a microscopic quantity of two-dimensional titanium carbide called MXene significantly improves the collection of electrical charges in a perovskite solar cell, increasing the final efficiency above 20%. The results of the research were published in Nature Materials. Perovskite thin film solar cell is a new promising technology of alternative energy sources that is being actively developed worldwide. One

How much photovoltaics (PV) would be needed to power the world sustainably?

The International Energy Agency has dubbed increased global cooling demand as one of the most critical blind spots in today’s energy debate. A new study entitled – Meeting Increased Global Cooling Demand with Photovoltaics during the 21st Century – yields critical new insight to a fundamental question: How much photovoltaics (PV) would be needed to power the world sustainably? The

HZB to hit world record for tandem perovskite-CIGS solar cell: 23.26% efficiency

A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world’s largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One

Cost-effective “photomicroreactor” based on luminescent solar concentrators

The sun is the most sustainable energy source available on our planet and could be used to power photochemical reactions. In the journal Angewandte Chemie, scientists present a widely applicable, cost-effective photomicroreactor. It is based on “Luminescent Solar Concentrators,” which harvest, convert, and make photons available for chemical reactions. Thus, the researchers were able to synthesize various substances, including two pharmaceuticals.

Agrivoltaics to Prove Mutually Beneficial Across Food, Water, Energy Nexus

A paper published in Nature Sustainability presents the first field-data assessment of outcomes of a multi-year study of agrivoltaics in dryland regions led by UA geographer Greg Barron-Gafford. Building resilience in renewable energy and food production is a fundamental challenge in today’s changing world, especially in regions susceptible to heat and drought. Agrivoltaics, the co-locating of agriculture and solar photovoltaic
