Scientists in Spain have fabricated a silver bismuth sulfide (AgBiS₂) material with an absorption coefficient that is claimed to be 5-10 times greater than any other material currently used for PV technology. A cell built with these nanocrystals showed a power conversion efficiency of 9.17%, an open-circuit voltage of 0.495V, a short-circuit current of 26.75mA/cm², and a fill factor of 63%.

French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.

Recent analysis from German consultancy Enervis has shown that only 40% of the electricity to be generated by solar capacity in Poland’s latest auction for utility scale renewables will be sold under the exercise’s contracts for difference regime, and that the remaining share will be sold under bilateral power purchase agreements or to the spot market.

France has set a new target under which it will install 5GW of new PV capacity per year.

With the Polish government planning to commission five gas power plants over the next five years, London-based thinktank Carbon Tracker has estimated just how costly the move will be, compared to deploying solar plants and energy storage instead.

Scientists have investigated how utility-scale solar may be used to power multistage flashing-brine recirculation (MSF-BR) water desalination plants in Aqaba, Jordan. They found the facility would be sufficient to provide the entire city with drinking water. The proposed system configuration comprises a 30 MW solar plant and a standar MSF-BR unit.

Germany’s Sunfarming is testing the new project design in cooperation with research centers Jülich and the Fraunhofer ISE.

According to Swiss consultancy Pexapark, around 11 GW of power purchase agreements were closed in Europe last year. For 2022, the analyst expects shorter deals and the presence of more new entrants.

The retirement of coal baseload capacity, some regulatory adjustments and high energy prices volatility could bode well for the deployment of batteries in Italy, and especially in Sicily. Problems, mostly related to the timing and the structure of the auction, remain, however. We spoke about it with Michele Scolaro, Aurora Energy Research Associate.

Residential-based energy storage will become the new ‘Boiler 2.0’ and could form part of a virtual power plant, providing a viable solution to the global energy crisis and helping us to achieve our net-zero goals.
