The device is claimed to be an ideal solution for deploying solar arrays on Mediterranean roof architecture.

An international research group has developed a solid oxide fuel cell that may be used in vehicles. The monolith device has an active cell area of around 18 cm2 and was built through common manufacturing processes. It was found to achieve a high power density of 5.6 kW/L, which the scientists said is comparable with that of the best performing fuel cells based on ceramic anodes.

Scientists in Germany have developed two kinds of solar cells based on n-type doped electron-collecting poly-Si on oxide (POLO) junctions with aluminum-alloyed p+ contacts. Both devices are claimed to be possible upgrades of PERC technologies. The best-performant cell is an IBC device showing a power conversion efficiency of 23.71%, an open-circuit voltage of 711.5mV, a short-circuit current of 41.3mA/cm2, and a fill factor of 80.9%.

Danish BIPV specialist Dansk Solenergi has added two more tiles to its product range – an 18.15%-efficient dark grey panel and a 16.7%-efficient terracotta product. Both panels have an operating temperature coefficient of -0.34% per degree Celsius.

Panasonic has unveiled a new product in Japan with a PV-based charging function that uses a heat pump and hot water storage unit to save energy by maintaining bathwater temperatures at constant levels.

The International Renewable Energy Agency has outlined a series of technical considerations for green hydrogen tracking systems. According to the document, a degree of flexibility should be taken into account in the short term to ensure that the nascent green hydrogen market can develop.

Developed by a Dutch consortium, the Hide and Shine Floating Solar (HAS FPV) technology is claimed to be extremely resistant to storms and harsh weather conditions. The modules can be submerged totally or partially and, in case of a severe storm, they can be submerged up to two meters below the surface.

Researchers in Saudi Arabia have fabricated an integrated fully PV-powered system to extract fresh water from the atmosphere. The system uses excess heat from the solar modules to evaporate and condense water that can then be used to grow crops. Part of the water is also used to cool down the solar modules through an active cooling technique.

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.

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.
