The Italian manufacturer said the product is based on a technical solution previously used for power downgrading. The device is said to be ideal for projects at altitudes greater than 1,000m.

Following its decision to switch from fixed feed-in tariffs to reverse auction bidding for the setting of solar incentives, the Vietnamese government has decided to devote the first two pilot auctions to floating PV. A first procurement exercise, for a project which could reach 100 MW of generation capacity, will be held this year.

Researchers in Denmark have developed water-based nanofibers coated with a biological PV substance which can be easily injected into the body. The developers say excitable cells in the heart and brain could be regenerated by being electrically stimulated with the solution.

The Tunisian Ministry of Mines and Energy has confirmed that Norway’s Scatec Solar has secured 300 MW at three sites. It also revealed that France’s Engie and China’s TBEA each picked up 100 MW projects. The lowest bid came in at $0.025/kWh, while $0.034/kWh was the highest offer.

U.S. scientists are trying to understand how non-fullerene small-molecule acceptors (NAFs) increase the efficiency of organic PV devices. They claim that methoxy groups embedded in the acceptors could facilitate an efficiency increase of approximately 6%.

2.5 MW of solar is being deployed at three project sites in Papua New Guinea, with commercial operations likely to begin within nine months. The installations will provide power in the island province of New Ireland at lower prices, while also improving access to electricity.

In a newly published policy document, Hanoi has urged regional governments and the country’s state-run utility, EVN, to suspend authorizations for new solar parks until further notice. Around 8.93 GW of utility-scale solar capacity is already approved for development in Vietnam, according to the Ministry of Industry and Trade.

An American research team developed the new formula by applying to bifacial cells the Shockley-Queisser triangle, which is used to calculate the maximum theoretical efficiency of a monofacial solar cell using a single p-n junction technology. According to the group’s findings, the triangle can help to clarify the deeper physical principles of the bifacial technology.

The Chinese manufacturer’s roadmap for its new module technology includes plans to raise panel output to 500 W. The Tiger modules are said to be fully compatible with the company’s existing module encapsulation processes and equipment.

Wind took the largest share of the awarded capacity, according to the preliminary results, but newly introduced limitations for such projects helped solar to take a significant portion of the allocated power for the first time in a Polish energy auction, with the highest bid coming in at $0.0608/kWh.
