New research shows vulnerability of TOPCon solar cells to contact corrosion
Researchers at the University of New South Wales claim to have identified new TOPCon contact degradation mechanisms that are significantly influenced by the combination of ions and aluminum-silver paste compositions. The primary degradation mechanism was a significant increase in series resistance.
Panasonic testing smart thermostats in residential heat pumps
Panasonic will integrate new smart thermostats and an energy management software in its Aquarea system from November. The new solutions are also designed to enable PV system owners to manage their heat pumps based on local weather forecasts.
Sharp unveils 610 W TOPCon solar panel with 22.58% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of over 80%.
Sharp unveils 450 W bifacial TOPCon module with 22.52% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of more than 80%.
Silfab launches 640 W utility-scale solar panels
The Canada-based manufacturer said its new panels have a temperature coefficient of -0.29% per C and an efficiency of up to 22.92%. They come with a 30-year power output guarantee for 89.3% of the initial yield.
Generac presents new residential batteries
The United States-based storage system provider said its new batteries are configurable in 3 kWh modular increments up to four cabinets per site. Their roundtrip efficiency ranges from 88% to 91%.
Lightweight ventilated BIPV system for low-load rooftop applications
Scientists in China have designed a ventilated building-integrated photovoltaic system that relies on flexible solar modules with a weight of 6 kg/m2. The system also uses an airflow channel under the PV panels to reduce their operating temperature and increase their power yield.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 28.8% efficiency
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
East-west vertical PV as antidote for soiling in desert regions
New research shows that east-west-oriented vertical PV installations can significantly help reduce soiling in desert environments. The scientists found that PV power generation can be up to 9% higher in vertical systems compared to conventional arrays.
New battery sizing approach for virtual synchronous generators, control-based grid-forming inverters
A team of researchers in Western Australia has outlined a new methodology to determine the minimum power rating of energy storage systems used for emergency under-frequency response. The ESS size must be calculated to maintain the frequency within the standard operating range.
