The mobility rEVolution: Zero-cobalt cathode for highly stable lithium-ion batteries
U.S. researchers say they have developed a way to make cobalt-free lithium-ion battery cathodes, while Ford says it has broken ground on a new $5.6 billion production complex for electric vehicles and batteries.
Solliance hits 30.1% efficiency on perovskite/silicon tandem solar cell
The Solliance consortium achieved a 29.2% record efficiency for the solar cell in November 2021, from just 28.7% in March 2020. In recent months, it increased the perovskite cell for the tandem device from 17.8% to 19.7%.
Model to assess microclimates in vertical agrivoltaic systems
Swedish researchers have developed a model to analyze the microclimate parameters of a vertically mounted agrivoltaic system. They validated their model by comparing its estimations with measurements of solar irradiance, PV module temperature, and ground temperature.
A case for residential solar sharing
Technische Universität München researchers have run a series of tests to investigate the growing share of rooftop PV in Germany. They found that the sale and purchase of electricity between households could reduce consumption peaks and prevent grid bottlenecks.
Clean energy cost savings motivates Republicans and Democrats alike
Researchers presented different messages about clean energy to groups from both political parties in the U.S. to learn what message motivated them the most. Cost savings won out, with the economy/jobs coming in second.
Agrivoltaics: Co-locating solar and agriculture yields mutual benefits
National labs and universities are exploring the synergies of co-locating solar with cattle or sheep, crops, pollinator-friendly native plants, soil rehabilitation and other ecosystem services.
Sunrise brief: Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Also on the rise: Flyover footage of a 6.5 MW community solar project in Maine. The PV Magazine states of solar tour stops in North Carolina. And more.
Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Researchers at the National Renewable Energy Laboratory made a breakthrough in high efficiency and stability for perovskite solar cells.
DOE funds $11 million battery research center at University of Michigan
The new research center will focus on the development of advanced batteries and fuel cells for electric vehicles.
Aluminum-sulfur battery for small-scale storage at $8.99/kWh
Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.
