Vietnam to hold auctions for 400 MW of floating solar 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.

PV against brain and heart diseases 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.

Gauging non-fullerene acceptors for organic PV 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%.

Denmark bets on green hydrogen The Danish government has agreed to provide $19 million in funds for two large-scale hydrogen projects under development on the Jutland peninsula. The two projects will produce green hydrogen for the transport sector from renewables sources. Denmark’s largest energy company, Ørsted, has also announced plans for an ambitious 2 MW electrolysis plant with appurtenant hydrogen storage.

New thermodynamic formula to calculate bifacial gains 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.
