Canadian scientists build micro III-V solar cells with record-breaking open circuit voltage
The proposed cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of 0.25 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).
EnerVenue to supply nickel-hydrogen batteries to RWE for pilot testing
RWE plans to cycle EnerVenue’s nickel-hydrogen energy storage technology at its testing facility in Milwaukee, Wisconsin. RWE says it wants to boost its own storage capacity to 6 GW by 2030.
Mercedes-Benz testing new solar paint
Mercedes-Benz said it is now evaluating a 20%-efficient, non-silicon photovoltaic coating that is significantly cheaper than conventional solar modules.
Fraunhofer ISE warns of risk from higher than expected UV-induced degradation in TOPCon, PERC, HJT cells
The researchers of the German institute explained that UV-induced degradation may cause larger than expected efficiency and voltage losses in all dominant cell technologies, including TOPCon devices. The scientists expect that silicon nitride layers could be used to enhance TOPCon UV stability compared to PECVD layers typically utilized in PERC and heterojunction cells.
