In a chat with pv magazine, Christian Breyer – Professor of Solar Economy at Finland’s Lappeenranta University of Technology – explains which consequences the war in Ukraine may have on Europe’s energy landscape. According to him, only an unprecedented development of renewable energies, heat pumps and storage may help address the current energy crisis.

The Japanese manufacturer blames increasing wafer prices and logistics costs for its decision.

Developed for applications in BIPV, vehicle-integrated solar and smart glasses, the solar cell was built with an ultra-thin, semi-transparent, triple-cation perovskite film and gold nanorods (Au NRs). The device achieved an open-circuit voltage of 1097.1mV, a short-circuit current of 17.11mA/cm² and a fill factor of 73.12%.

The Norwegian renewable energy developer said its solar power plants are still intact and can be operated remotely. It is currently assisting its Ukrainian employees by offering transportation, accommodation and other immediate support.

Solar modules from Trina Solar, Canadian Solar, and Felicity Solar were tested in a prototype of a photovoltaic-thermal collector that uses excess heat from the PV elements to heat water. The system uses a thermally insulated helical coil heat exchanger to recover panel heat and a solenoid valve to allow water recirculation when the temperature below the PV module rises significantly.

Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that are at least two years old. The new product is claimed to increase power yield by up to 7% and to have a payback time of 2.5 to four years depending on the dust level of the site.

The 19.2%-efficient perovskite cells used in the module rely on an electron layer based on tin oxide that was deposited via chemical bath deposition. This technique, according to the device’s creators, has made it possible to have a relatively small drop in efficiency from small cells to the 40cm² module.

The tandem cell was fabricated by German scientists through a process flow that is compatible with industrial, mainstream PERC technologies. According to its creators, the device has the potential to exceed efficiencies of over 29% with adjustments in the perovskite thickness and bandgap.

The planned storage capacity will come from 20 projects selected by Italian grid operator Terna through the latest capacity market auction. Half of them will be located on the island of Sardinia.

Developed by Germany’s Fraunhofer ISE, the cell is manufactured with metallization based on a plating process. The device was built with galvanic nickel/copper/silver contacts instead of common silver contacts.
