UNSW researchers investigating the impact of electron irradiation on PERC and TOPCon solar cell performance have identified bulk lifetime degradation as main power loss cause. Their work stresses the need for increasing radiation tolerance in commercial space silicon solar cells.

In a new scientific paper, the Chinese solar manufacturer explained that the 27.81%-efficient hybrid interdigitated back-contact cell it unveiled in April is based on passivated tunneling contacts and dielectric passivation layers, while also incorporating both n-type and p-type contacts.

Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.

Japanese utility Tohoku Electric Power is using Sharp’s residential batteries and AI-powered energy management systems to balance grid demand and optimise household solar energy use. Customers in the program can earn points redeemable for local products.

The high-voltage grid transmission operator said the condensers will be deployed at five strategic sites across New South Wales.

A Chinese research group claims to have achieved remarkable efficiency and stability in a solar cell based on a perovskite absorber incorporating MXene, a novel type of 2D material known for its excellent conductivity, chemical stability, and thermal resilience. The device reportedly retained 80% of its initial efficiency after 500 hours.

Researchers in Canada have proposed using gravity-based energy storage in high-rise buildings, in combination with photovoltaic facades, small wind turbines, and lithium-ion batteries. Their modeling indicated that this hybrid system could achieve a levelized cost of energy ranging from $0.051/kWh to $0.111/kWh.

The Chinese manufacturer said its new inverters can deliver 160% overload for 200 ms in off-grid mode, ensuring stable startup of heavy loads. The IP66-rated products feature a maximum efficiency of 97.6% and a European efficiency of 97.2%.

With silver prices nearing $75 per ounce, researchers from the University of New South Wales and the Fraunhofer Institute for Solar Energy Systems tell pv magazine that efforts to reduce silver use in solar cells will not compromise module quality if properly engineered.
