Polysilicon prices persist in potential trend downward, governed by unfavorable factors
In a new weekly update for pv magazine, OPIS, a Dow Jones company, offers bite-sized analysis on solar PV module supply and price trends.
German startup unveils PV charging-parking system for e-scooters, bikes
German startup Domum has developed PV charging-parking systems for e-scooters and e-bikes. They use up to 660 W of solar panels.
Hydrogen batteries vs. lithium-ion batteries
Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.
Inverter undersizing not universally effective to reduce soiling losses
An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter undersizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.
U.S. Boiler unveils hydronic heat pump for residential applications
The US-based manufacturer said its new heat pump system has 5-ton capacity and a coefficient of performance of up to 3.95. It uses difluoromethane (R32) as the refrigerant and relies on DC inverter enhanced vapor injection (EVI) technology.
AGC Automotive Europe unveils photovoltaic panoramic sunroof for passenger vehicles
The Belgian automotive company said system can integrate either TOPCon, HJT, or xBC solar cells. The VIPV unit features a glass-glass construction and it does not need a roller blind system.
Citizen Solar introduces 590 W TOPCon bifacial module with 22.84% efficiency
The Indian manufacturer said its new TOPCon panels are built with 144 half-cut solar cells designed with 16 busbars. The temperature coefficient is -0.29% per C.
BASF, Worldlight release new PV module frame based on polyurethane
BASF and Worldlight have developed a new PV module frame based on polyurethane. The manufacturers claim that the new solution offers superior insulation and a longer lifespan than aluminum frames.
Mercedes-Benz factory in Germany to host 11 MWh organic flow battery
A Mercedes-Benz factory in Germany is set to host an 11 MWh organic flow battery to store solar energy generated by its rooftop PV installation. Germany’s CMBlu has provided its Organic SolidFlow technology for the project.
Perovskite quantum dot solar cell achieves record-breaking efficiency of 12.70%
Conceived by South Korean scientists, the cell was built with an electron transport layer made of tin oxide via a low-temperature process. The device reportedly achieved the highest power conversion efficiency ever reported for flexible quantum dot solar cells.
