Also on the rise: Canadian Solar reports strong quarterly results. Virtual power plant provider raises $120 million. And more.

The US National Renewable Energy Laboratory (NREL) has released a new, interactive version of its research cell efficiency chart for a range of PV technologies.

Puerto Rico’s power grid requires more than $130 billion in repairs after recent hurricanes. Solar and storage companies have provided distributed energy solutions in the aftermath of increasing storms.

Also on the rise: Michigan’s regulator appears friendlier to solar. Canadian Solar’s battery business inks a large supply agreement for a global investor. And more.

Longi said it has achieved a 26.81% efficiency rating for an unspecified heterojunction solar cell, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).

Batteries provided by CSI are central to UBS’ energy storage strategy and part of the expansion of its US infrastructure business

Solar Earth claims its 42-Watt sidewalk-mounted PV system can provide 75% of a traffic intersection’s power in an outage, while the utility will have to cover the remainder with batteries or a generator.

Researchers at the National Renewable Energy Laboratory modeled the benefits of PV in highly glazed skyscrapers.

A U.S.-Canadian research group has built an all-perovskite tandem solar device with a record-breaking open-circuit voltage of 2.19 eV, which they achieved by reducing recombination at the electron transport layer.

A grid modeling firm proposes an underground high-voltage DC transmission overlay for the continental U.S. that, along with increased solar deployment and even greater wind deployment, would help reduce climate pollutants and electricity costs.
