Australian scientists have built a perovskite solar cell based on 2D and 3D salts. By adding a fluorinated lead salt in the processing solution – normally used to form 3D methylammonium lead iodide – they were able to achieve a 21.1% efficiency, an open-circuit voltage of 1.12 V, a short-circuit current of 22.4 mA/cm2, and a fill factor of 84%.

The PV module relies on Jinko’s TOPCon mono cell technology, for which a record efficiency of 24.9% was announced last week. TÜV Rheinland has confirmed the result.

The Korea Energy Agency (KEA) will likely launch two 2 GW tenders in April and October. These will include the procurement of large-scale solar PV parks for the first time.

The tender will be open to PV projects ranging in size from 10 to 20 MW. The Turkish government has set a ceiling price of TRY0.35 ($0.047)/kWh for the procurement exercise. The selected facilities will be located across 74 grid connection points and will have to rely on locally produced modules.

Researchers in the Netherlands and Singapore have measured irradiance-weighted average temperatures of floating PV systems in both countries and have compared the results with reference rooftop and ground-mounted PV systems. They have discovered that floating PV systems with open structures, which allow wind to pass beneath the modules, can provide a higher heat loss coefficient.

The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.

Italian researchers have engineered a hole extraction layer with water-splitting additives to reduce the impact of moisture in perovskite PV devices. They claim that the method ensured a power conversion efficiency of more than 9% in perovskite cells stored for a month in a water-saturated atmosphere.

The Netherlands Authority for Consumers & Markets has established that the first-come, first-served principle applied by grid operators is the correct approach to manage current grid congestion. The decision was taken to resolve a legal dispute between Liander and an agricultural entrepreneur that was denied grid access for a PV project.

A Slovenian research team has analyzed the behavior of a full-size cell PV module and several 1/6 cell panels under partial shading and has come to the obvious conclusion that the cell cut panels suffer fewer energy losses. They also found, however, that the orientation of the cells connected in series should be aligned as much as possible with the shade shape to lower the losses and to minimize reverse cell voltage.

Gambia’s national utility is seeking proposals for an energy and water audit of its water operations. Selected consultants will assess the possibility of using solar to improve energy efficiency. The utility will consider floating PV, rooftop arrays, and solar pumps.
