The Fraunhofer ISE has developed an electro-optically optimized transparent conductive oxide layer that can reportedly improve the efficiency of perovskite-silicon tandem solar cells. A device built with the film achieved remarkable efficiency and fill factor.

New research from the United Kingdom claims that ground mounted PV facilities have a negative effect on bat activity. According to the scientists, the panels may be causing some bats to alter their flight paths, potentially resulting in further fragmentation of the ecological landscape.

The model utilizes deep learning and image processing techniques and is said to offer “superior performance.” In the future, it might be able to differ between panels of PV and solar thermal systems.

Solar pre-cooling consists of using residential PV systems to run air conditioners to pre-cool residential and commercial buildings. It offers benefits in terms of mitigating low minimum demand in electricity networks, flattening the grid’s net demand profile, and reducing electricity bills.

In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for South America in July. The data show that South America experienced temperatures up to 15 C above winter averages, and that most of the continent saw higher than normal radiation. The Chilean Andine, especially Altiplano in the Atacama Desert, which has recorded the highest incidence of irradiance in the world, recorded values 10% above normal.

Biwatt Power, a Chinese manufacturer, has developed new residential sodium-ion batteries with an efficiency rate of 97% and a projected lifespan of more than 3,000 cycles.

The University of Sevilla has designed a PV-powered “smart” canopy that activates a thermal conditioning system to reduce extreme heat by up to 20 C.

Maxeon is set to invest $1 billion in the construction of a 3 GW TOPCon cell and module plant in the United States.

The port of Valencia, Spain, is assessing the performance a vertical PV wall featuring 21 solar modules, with 8.6 kW of total capacity. A successful pilot project could pave the way for a larger vertical PV system on the port’s breakwaters.

Researchers in Taiwan are proposing a market-based incentive scheme to help property owners to move from using their roofs for illegal dwellings to rooftop solar power generation. They found these owners should be rewarded for solar power generation but also be compensated for the income loss due to the removal of illegal rentals.
