According to its creator, Swedish start-up Evolar, the new technology can be applied to existing production lines for crystalline silicon modules and increase a product’s efficiency by around 5%.

Researchers in Egypt have tested a new solar module cleaning technique for solar arrays in arid regions. They claim that the combination of nano-coatings with vibration mechanisms on the backs of modules can reduce manual cleaning requirements.

French cooperative Céléwatt and engineering company Mécojit are building a new, 250 kW solar park in southwestern France. The solar panels are installed on a raw wood structure, sourced from the surrounding forests, to promote local employment and a regional natural resource.

Solarpower Europe has called on member states to put solar and battery storage front and center when it comes to drawing up the Recovery and Resilience plans needed to secure a slice of the bloc’s proposed €672.5 billion post-Covid stimulus package.

Spanish company Isigenere has deployed a 739 kW floating array on a quarry lake near Dettelbach, in the Bavaria region. The plant is relying on 1,896 panels with a power output of 395 W each.

The in-country analyst has revised up its expectation for this year and says a healthy unsubsidized project pipeline will keep the numbers ticking over in 2021. The spending plans necessary to ramp up renewables targets in the next five-year plan, though, could put the nation on a collision course with the EU.

French companies Ombrea and RES are partnering on the development of special PV shade systems for agrivoltaic projects. The devices will be equipped with artificial intelligence technologies to make them react to unfavorable weather conditions.

South Korean scientists have built a kesterite solar cell based on a zinc tin oxide (ZTO) buffer layer. It offers almost the same efficiency as kesterite cells based on toxic cadmium sulfide buffer layers, as the energy of the electrons between the kesterite absorber layer and ZTO buffer layer are aligned.

Heliogen, which was founded by serial entrepreneur Bill Gross, aims to revitalize concentrated solar power with sCO2 tech to cut costs, water use, and plant footprints in industrial applications not suited to solar PV.

A pilot project in China was brought online this month, combining 10 MW of PV with electrolyzers for hydrogen production and carbon dioxide hydrogenation to synthesize methanol. The methanol is supplied to the chemical industry, or can be converted back into hydrogen for energy use. And the project’s creators say their next goal is scaling the project up to 10 or even 100 times its current size.
