Iberdrola seeks innovative solutions for agrivoltaics

The Spanish utility said agrivoltaic projects and solutions will be evaluated based on costs, technological maturity, crop diversity, and level of digitization among other things.

Harvard scientists unveil solid-state lithium battery that can be charged and discharged at least 10,000 times

US scientists have created a new design for lithium-metal, solid-state batteries that should avoid the formation of dendrites that grow into the electrolyte. Their multilayered battery could potentially recharge electric vehicles within 10 to 20 minutes.

New discovery promises to bring singlet fission enhanced C-Si solar cells nearer to commercial production

New research from Australia has shown that singlet fission solar cells do not only have the potential to raise the theoretical efficiency of the PV technology to unexpected levels but also to provide a better temperature behavior and longer duration compared to conventional PV devices. The scientists believe that this technique may help conventional crystalline silicon solar cell technologies reach efficiencies close to 30%.

New York state funds study on benefits of grazing for PV

Sheep and solar farms can exist symbiotically, and the American Solar Grazing Association says that now is the time to convert that relationship into a full-scale industry.

Best membrane for non-aqueous redox flow batteries

A Chinese-Finnish research team has identified composite membranes as the best future option for non-aqueous redox flow batteries.

Air-assisted water spray for PV module cooling

Turkish researchers have developed a cooling technique in which water is sprayed via an air-assisted external mixing flat fan nozzle. The system can produce smaller droplet sizes to ensure the even distribution of water on panels.

Future of cadmium telluride PV tech

In the third interview of a series, pv magazine spoke to Prof. Arvind Shah of École polytechnique fédérale de Lausanne and Associate Prof. Alessandro Romeo from the University of Verona about the challenges and opportunities of cadmium telluride (CdTe) PV tech. They said there is still potential to ramp up efficiency and cut costs, and claimed that the toxicity of cadmium should not be seen as a serious concern.

Micro III-V solar cell with 33.8% efficiency

Developed by a French-Canadian research group, the triple-junction cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of only 0.089 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).

Exploring defects in a solid-state electrolyte

Scientists in the U.S. used sophisticated imaging techniques to observe previously unknown defects in the crystalline structure of a solid-state electrolyte. The scientists theorize that these defects could play an important role in the electrolyte’s performance, and that designing them more carefully into the material could have impressive results.

Rooftop CPV-thermal tech to produce electricity and freshwater

It’s claimed the decentralized desalination system can deliver a levelized cost for desalinated water of US$0.7-4.3/m3, depending on PV costs and electricity prices. It was built with several concentrated photovoltaic/thermal (CPV-T) collectors, a hot water tank, a V-MEMD module, a seawater feed tank, and a distillate tank.
