Technology and R&D

Scientists at the U.K.’s Faraday Institution have been able to observe degradation mechanisms at the lithium metal anode in a solid state battery, and made several discoveries which could improve the performance and design of future solid-state lithium-ion batteries.

The U.S. National Renewable Energy Laboratory reports further progress in bringing down the cost of III-V solar cells. Scientists have refined their ‘brand new, 50-year-old’ D-HVPE technology to speed up the production rate for gallium arsenide solar cells by a factor of more than 20. The development is a potential step toward making incredibly efficient solar cells cost effective for everyday purposes.

Scientists at Rice University in Texas have developed a device which converts heat into light by squeezing it into a smaller bandgap. The ‘hyperbolic thermal emitter’ could be combined with a PV system to convert energy otherwise wasted as heat – a development the researchers say could drastically increase efficiency.

A satellite launched from Florida last month has successfully unfurled its ‘solar sail’ in an early test of a new type of sunlight powered propulsion. The Planetary Society aims to demonstrate the technology as a viable way to propel small satellites, greatly lowering the cost of space exploration.

Research on bifacial solar panel performance has moved performance analysis closer to a standardized practice than ever before. More field tests are underway across the United States, and the first waves of data are expected this year. These tests will help standardize a predictive model for bifacial projects that is bankable.

Hyundai has unveiled its new hybrid, the Hyundai Sonata, complete with integrated solar cells. The Sonata’s unveiling joins Toyota and Lightyear in integrating solar PV with EVs.

Study claims that investment in a new 1GW nuclear power plant leads to average losses of approximately 4.8 billion euros. It further argues that the technology’s dangerous radioactivity emissions and proliferation risks do not qualify it as a ‘clean’ energy solution to be considered for addressing climate change. Yet still, governments are incorporating the technology into clean energy plans around the world.

California based Hanergy subsidiary Miasolé has broken its own internal record for thin film cell efficiency, surpassing the 20% mark. The efficiency of 20.56% on a flexible substrate has been confirmed by U.S. National Renewable Energy Laboratory.

Scientists from the University of Kansas say adding a layer of two-dimensional semiconductor molybdenum disulfide can greatly improve the performance of organic solar cells. The research could also inform efforts to engineer the interface between layers in hybrid organic cells.

Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.
