Developed by Malaysian scientists, the proposed multi-level aluminum fin heat sinks (MLFHS) were found able to reduce the module operating temperature by up to 8.45 degrees Celsius and increase power yield by up to 10.75%. The system cost was estimated at $0.60/W.

An international group of researchers has achieved the highest fill factor reported for perovskite cells of any size to date. The device was fabricated with a nitrogen-doped titanium oxide (TiOxNy) electron transport layer aimed at improving charge transport between the cell’s perovskite absorber and the electrodes.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

The analyst also forecasts strong growth for the storage business and a significant increase in PPAs for photovoltaic projects in Europe. It also said the newly installed PV capacity for 2021 reached 183 GW.

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

Developed in Spain, the Arca system integrates solar panels, power electronics, and energy storage. Arca Lite has a rated power of 490 Wp, and Arca Plus of 980 Wp.

Mercedes-Benz has teamed up with ProLogium to integrate solid-state battery technology into a range of passenger vehicles; Panasonic and Toyota have launched an industrial-academic collaborative research program concerned with battery resources and recycling; and LG Energy Solution plans to spend $2.1 billion with General Motors to build another electric vehicle battery plant in the U.S.

According to BloombergNEF, electrolyzer shipments may reach up to 2.5GW in 2022, up significantly from 458MW last year. China and the United States will become the world’s first and second markets, respectively.

The panel features 108 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.341% per degree Celsius and its power tolerance reaches up to 5%.

Researchers from the University of New South Wales (UNSW) predict that growth to 60TW of photovoltaics needed to rapidly reduce emissions to ‘net zero’ and limit global warming to <2 °C could require up to 486 Mt of aluminium by 2050. A key concern for this large aluminium demand is its large global warming potential.
