Technology and R&D

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).

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.

Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.

A compact, “motionless” wind turbine with a magnetic generator designed for large commercial rooftops provides 5 kW of capacity per unit. Aeromine Technologies secured Series A funding for scaling its innovative design.

Gamesa Electric has released a white paper on losses due to harmonics in PV plants, including an independent study that compares the performance of ultra-low total harmonic distortion inverters.

The Durable Module Materials consortium (DuraMAT) announced in its latest annual report the availability of new PV forecasting tools, and new research results towards the goal of more reliable PV modules.
