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.

Estonia halts permitting for large scale PV in northeastern regions for national defense reasons

The country’s Ministry of Defence has decided to ban large scale solar plants in some regions bordering Russia claiming that these facilities may affect radio system performance. State-owned utility Eesti Energia is opposing this measure, stating the interested regions are the most suitable for the construction of big solar plants.

A solar cell you could make on the moon

As part of a project headed by the European Space Agency investigating materials for long-term missions, scientists in Estonia are investigating a tiny iron-based crystal as a potential solar cell material. So far, the material has not achieved the sort of efficiency that would spark a lot of interest. These researchers, however, are interested in it for a different reason: Beyond planet Earth, the material is abundant enough that it could eventually be manufactured on the Moon or even Mars.


Semi-transparent antimony trisulfide PV cell for solar window applications

The 5.5%-efficient cell was fabricated through a low-temperature, two-step manufacturing process that is compatible with existing window glass manufacturing technology. Cells made with 70nm antimony trisulfide films achieved the best fill factor of around 57%, while the highest power conversion efficiencies were achieved with films ranging from 70 to 100nm.

BIPV modules from Estonia

Estonian start-up recently raised €6.4 million from a group of investors led by Germany’s Baywa r.e. The company will use the funds to commercialize its three BIPV modules with power outputs of 110 to 160 W. All products rely on a 0.5 mm metal back sheet with highly durable pural coating.


Commission flags up €875m renewables project fund

A call for grant proposals has been promised this month, with the bloc’s executive yesterday firing the gun on a separate exercise related to cross-border EU energy infrastructure projects.

Portable hydrogen fuel cell generator with power output of 400 W

The generator can be combined with batteries, solar panels, or small wind turbines. It is based on a proton exchange membrane fuel cell technology and is claimed to have a minimum lifetime of 5,000 working hours.
