Challenging plans to deploy PV on dikes

Dutch researchers are trying to determine whether large-scale PV projects can be deployed on flood-control dikes across the Netherlands. A 5 MW solar project has already been built on a dike near Groningen, but the researchers believe there is potential to build up to 2.9 GW of PV on such embankments.

Bangladesh net metering requirement may deter solar pump owners

The government has finally issued guidelines on how solar-powered irrigation system owners can be paid for exporting power back to the grid. However, for those who expect to have to use grid power to augment solar from time to time, there could be a sting in the tail.

Tesla may become power provider in Germany

The high-profile electric car maker is conducting a survey of German customers to gauge their interest in a Tesla electricity tariff.

‘Spontaneous de-doping’ for 17.8%-efficient perovskite mini-module

U.S. scientists have found a new ‘de-doping’ process in perovskite solar cells that could cut production costs and produce better devices. They have used this to fabricate a mini-module with 17.8% efficiency.

Solar for parking machines

New Zealand researchers have proposed a way to assess the technical and economic feasibility of PV-powered parking machines. Solar might be an ideal solution, but the siting of the machines is critical and should be planned in advance, in line with available solar radiation and potential shading.

Low-cost catalysts for hydrogen production

Researchers in Singapore have taken a deep dive into spinel oxides – a class of materials known to act as a catalyst in the production of hydrogen through water electrolysis. Better understanding of how the materials work enabled the scientists to develop a machine learning model to predict their efficiency.

Recom unveils tri-cut solar panel series

The Jaguar series, with 20.81% efficiency and 445 W of maximum output, may be a solution for installations with space constraints. The panels are based on a special cell design, which Recom describes as an evolution of the half-cut cell concept.

Getting serious about soiling

Scientists in the United States and India are investigating the impacts of soiling on PV installations in the Indian state of Gujarat. The group, which found that soiling losses for the state could add up to $12 million per year, is looking for low-cost ways to monitor and reduce the impacts of soiling on modules in the field.

Looking to phosphorous for next-gen batteries

Scientists in the United States have fabricated a working lithium-ion battery using a phosphorous-based anode. The batteries show significantly higher capacity than today’s lithium-ion tech, and could serve as a guideline for future design of high-performance anodes for Li-ion batteries.

CPV panels for agrivoltaics

Swiss start-up Insolight has raised €4.6 million to bring its concentrating PV module technology to commercial production. The panels have a claimed efficiency of 30% and power output of 160 W. Originally conceived for rootop solar, the product is now being recommended as an interesting option for agrivoltaic projects.
