Solarstone opens 60 MW BIPV module factory in Estonia

Solarstone, an Estonian producer of building-integrated photovoltaic (BIPV) solar roofs, has opened a 60 MW manufacturing facility in Viljandi, Estonia, to produce a broader range of design and performance specifications.


Novel approach to build bismuth trisulfide thin-film solar cells

Researchers in Estonia applied for the first time the close-spaced sublimation (CSS) deposition technique to manufacture solar cells based on bismuth trisulfide (Sb2S3). The resulting devices showed limited power conversion efficiency so far, but the scientists claim the new process paves the way for the development of future earth-abundant inorganic PV materials.

Antimony trisulfide PV cell hits 4.9% efficiency with fluorene-based HTMs

An international research group used the ultrasonic spray pyrolysis (USP) method to fabricate an antimony trisulfide PV cell with high power conversion efficiency and remarkable average visible transmittance. The cell has an active area of 7.06 mm2.


The Hydrogen Stream: Green hydrogen generation on the Baltic Sea

Salzgitter Flachstahl says it will produce hydrogen with green electricity from a wind power plant under construction by Iberdrola in the Baltic Sea. German Minister of Economics Robert Habeck, meanwhile, has announced funding for the Salzgitter Low CO2 Steelmaking transformation program.


Estonia to host 550 MW pumped hydro storage facility

Energiasalv has secured a construction permit to build a 6 GWh pumped hydro storage plant in Paldiski. Work on the facility is planned to start in the summer of 2024.


Sustainable Capital offers €100m of financing for EU hydrogen companies

The European Union and its funding mechanisms for hydrogen are attracting the interest of private funds and investors. Sustainable Capital says it wants to co-invest in preselected companies, mainly in the mobility sector, focusing on Estonia, Germany, and the Netherlands.


New photovoltaic tiles from Estonia

Estonian startup Solarstone has developed two solar tiles with an efficiency of up to 19.5% and an operating temperature coefficient of -0.41% per C. It recently secured €10 million in funds to expand sales across Europe.


EU energy fund to commit $514 million for solar projects at Romanian mining waste sites

Panels will be installed at waste sites in five mining towns as part of the latest, €2.4 billion ($2.57 million) round of investment from a fund set up to help coal-dependent European member states with the energy transition.

The Hydrogen Stream: World’s first hydrogen-powered towboat

Shipbuilder Hermann Barthel has developed the world’s first push boat to combine battery-electric propulsion with hydrogen and fuel cell technology. Iberdrola and Fertiberia, meanwhile, have commissioned Europe’s largest green hydrogen production plant.


Novel power electronic converter for BIPV

Conceived by researchers in Estonia, the device is claimed to be compatible with both crystalline silicon and thin-film BIPV panels and to manage, easily, different voltage levels. It can be applied either in solar facades or BIPV rooftop arrays.
