The Sahara Desert, and the Sahel region, could be set to take advantage of large-scale wind and solar power projects covering huge surfaces.

The benefits of deploying bifacial solar panels on single-axis trackers are touted like snake oil these days, with promises of anywhere from 5 to 50% gains in energy output compared with a monofacial panel. Unfortunately, the field data that might delineate the actual energy gain of a bifacial panel on a tracker are hard to acquire, and the data that are available typically describe small-scale tests under tightly defined conditions.

The Australian Renewable Energy Agency (ARENA) has offered funding to nine Australian universities and research organizations to propel innovation in green hydrogen export.

The scientists have shown how the control of the molecular structure of a semiconductor polymer makes it possible to obtain a PV conversion efficiency of more than 10% for an organic solar cell.

The algorithm is said to be able to examine the relationship between weather forecast data and the projection of electric circuit parameters. Through this innovation, Purdue University researchers claim they can interpret the routinely collected maximum power point (MPP) time-series data, to assess the time-dependent “health” of installed solar modules.

Researchers from the Idaho National Laboratory have developed a new type of electrode for hydrogen production through electrolysis – water splitting. The team has used the electrode to demonstrate efficient hydrogen electrolysis at temperatures far lower than previously possible, which could lead to significant cost reductions in large-scale hydrogen production.

Researchers from Finland’s Aalto University and the Michigan Technological University, in the US, say they have demonstrated the cost per unit of power of black-Si PERC cells could fall 10.8%, despite an increase in cell processing cost.

Twelve signatories from the energy and consumer goods industry have sent an open letter to the EU and U.K., calling for continued cooperation after Brexit to protect both consumer, and business, interests. The document highlights the importance of tariff-free electricity trading as intermittent renewable energy will require a higher degree of market integration.

A research team from South Korea’s Ulsan National Institute of Science and Technology has demonstrated a new process for the creation of organic solar cells. Using this method, the team has created cells with a conversion efficiency up to 12.01%.

Researchers from the University of California, Los Angeles, have set a new record 22.4% conversion efficiency for a tandem cell combining a lead-based perovskite layer with CIGS technology. The record has been confirmed by the U.S. National Renewable Energy Laboratory.
