Perovskite solar cell with record-breaking fill factor of 86.6%
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.
Maxeon to offer IBC solar panels in the US
The company announced an expanded commercial and industrial push in the states and a partnership with protection and performance plan provider Omnidian. Maxeon said it will offer its interdigitated back contact (IBC) panels in the US.
Multi-level fin heat sinks for solar module cooling
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.
US microgrid project using vanadium redox flow battery
SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.
Belectric builds another floating solar park in Israel
The project is the fourth floating solar array that Belectric develops and builds in Israel.
Chile’s first fast-charging station for EVs
The recharging station will operate 24 hours a day and in a flexible format, which will allow fleets of electric buses, last-mile distribution vehicles, trucks, taxis and private electric cars to be supplied through fast charging points.
The panel and the city
US researchers have investigated how rooftop PV systems may affect air and building temperature in urban environments and, conversely, how the urban heat island (UHI) effect may have a negative impact on PV system performance. Their work considered urban air temperature, urban air pollution, the partial shading of the PV system, soiling, building heating and cooling loads, and outdoor shade.
