The independent test lab Kiwa PVEL names 53 manufacturers and 388 models–a record number of Top Performers in the ten-year history of the Scorecard.

Although promptly deploying grid-enhancing technologies and advanced conductors could speed interconnection in the short term, a new federal transmission rule will improve interconnection only once new transmission is built, said panelists on a webinar.

Researchers from the U.S. and South Korea have developed a method to make high-quality perovskite films at room temperature. The film was tested in a conventional perovskite solar cell architecture and the result was a power conversion efficiency of exceeding 24%.

Also on the rise: Vermont becomes first state with Climate Superfund Act. Solar project developers face opposition from Joshua Tree conservationists. And more.

Tandem PV integrates perovskites with traditional silicon solar panels, a technology that promises increased power output.

JinkoSolar says it has achieved a 33.24% efficiency rating for its perovskite-silicon tandem solar cells, confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).

Also on the rise: Are false pretenses driving solar cell tariff case? Long-duration energy storage poised to outcompete lithium-ion batteries. And more.

Using 600% less voltage to produce hydrogen, a research team at the University of Illinois Chicago has developed a new method for splitting water.

Also on the rise: Technology-neutral proposed tax credit called ‘game-changing policy’. Less than 3% of farmland could power the Midwest. And more.

As the White House encourages utilities to use advanced conductors to help interconnect new renewable generation, the federally-owned utility Bonneville Power is moving slowly to use the high-capacity conductors, analysts said.
