New kesterite solar cell with 8.7% efficiency

Estonian researchers have developed a new monograin powder technology made of microcrystals, which can form parallel connected miniature solar cells in a large module. By replacing copper with silver in the absorber material, the researchers were able to increase the efficiency of the cells by more than 2%.

Engie secures solar PPA in France, vows to shut 1 GW of coal in Latin America

At the ongoing COP25 summit in Madrid, the French energy group announced the closure of nearly 1 GW of coal assets in Chile and Peru between 2019 and 2024. It also secured a PPA for an 18 MW solar park that will come online in southern France in June 2021.

Risen Energy unveils 500 Wp+ half cut mono PERC modules

The PV manufacturer announced the development of the new solar panels, which feature new M12 series monocrystalline wafers, at a conference on Thursday in the Chinese city of Ningbo. The 50-cell modules are actually slightly bigger than 72-cell designs with 156.75 mm wafers, it said.

Power Ledger, Japan’s Kepco extend blockchain energy collaboration

100% renewables means 95% less water consumption for conventional power generation

According to a new study by Finland’s LUT University, solar PV consumes between 2% and 15% of the water that coal and nuclear power plants use to produce just 1 MWh of output; for wind, this percentage ranges from 0.1% to 14%. Under the researchers’ best policy scenario, water consumption could be reduced by 75.1% by 2030, compared to 2015 levels.
