Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon bottom cell with a bandgap of 1.1 eV. The device achieved an open-circuit voltage of 2.84 V, a short-circuit current of 11.6 mA cm–2, and a fill factor of 74%.

Trina Storage has developed a 4.07 MWh energy storage system featuring its in-house 306 Ah lithium iron phosphate battery cells, configured with 10 racks of four battery packs.

An energy makeover of a heritage-listed church built in 1965, including new solar PV roof, new insulation, new windows, and heat pumps, enables it produce 149% of its energy requirements. The achievement garnered the project team the Norman Foster Solar Award 2023.

Ahead of the upcoming introduction of EU Ecodesign and Energy Label policy measures for solar PV products, SolarPower Europe brings some reflections on the topic, adding insights to the ongoing industry discussions.

The Japanese electronics manufacturer said its new heat pumps are suitable for commercial, industrial, and multi-dwelling residential applications. The new products feature a rated power ranging from 50 kW to 80 kW and a coefficient of performance spanning from 3.2 to 3.4.

A Spanish-Italian research team has investigated different system configurations for bifacial agrivoltaic solar arrays deployed in olive groves and has found that the solar modules’ tilt angle has a significant impact on power yield while their height plays a crucial role on increasing agricultural yield.

A Japanese-German research team has fabricated a TOPCon PV device by replacing common ion implantation techniques with plasma immersion ion implantation (PIII). The resulting device showed almost the same efficiency as TOPCon cells produced with conventional Beam line ion implantation systems.

Netherlands-based Autarco has developed a new mounting structure for large PV modules in commercial and industrial arrays.

Sharp has developed vehicle-to-home (V2H) electric-vehicle chargers for PV-powered homes, featuring 6 kW of charging/discharging rated power and an input DC voltage of 340 V. The wall-mounted devices are suitable for indoor and outdoor environments.

The scientists built the panel with perovskite solar cells treated with trifluoromethane sulfonate to combat iodide defects. The mini module reportedly achieved the highest efficiency ever recorded for its size to date, with the result being confirmed by the US National Renewable Energy Laboratory (NREL).
