Researchers in China have designed an organic solar cell the uses an acceptor based on selenium as an alternative to commonly utilized non-fullerene acceptors. The new acceptor enabled the cell to have reduced non-radiative recombination loss and improved dielectric constant.

Beny New Energy says its new charger can deliver power at a range of 360 kW—600 kW. It supports various connection standards.

The research team said the cell also achieved remarkable thermal stability, as it was able to retain 90% of its original efficiency for over 1,000 h. The device uses a self-assembled monolayer to stabilize the interface between the perovskite absorber and the hole transport layer.

New research from India claims solar modules with 3.2 mm-thick front glass may not be strong enough to withstand storms producing big hailstones. The scientists found that a front glass of at least 4 mm should be used to avoid significant damage.

China-based researchers have developed a model for photovoltaic pavement, achieving a potential electrical output of 0.68 kWh/m2 and an efficiency of 14.71%. Through simulations across 255 Chinese cities, they have determined that electricity potential ranges from 0.70 kWh/W to 1.83 kWh/W.

The additive consists of a molecule known as 4-guanidinobenzoic acid hydrochloride (GBAC), which is a raw material and intermediate commonly utilized in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields. The solar cell has a p–i–n structure and, thanks to the new additive, showed considerably reduced defect density on the perovskite film, which in turn results in reduced non-radiative recombinations.

Researchers in Hong Kong have designed an agrivoltaic system that uses blockchain tech and smart contracts to reduce uncertainties between PV system operators and grape farmers. The proposed system uses rainwater to clean solar panels and provide irrigation.

A local environmental organization has published pictures of the stranded array which appeared last week on two beaches. Hong Kong’s Agriculture, Fisheries and Conservation Department is currently investigating where the installation came from.

A research team in Hong Kong has built a solar window that can generate power on the external side via a luminescent solar concentrator and thermal energy on the internal side via transparent solar absorbers.

The cell is based on ferrocene and is claimed to retain more than 98% of its initial efficiency after continuously operating at the maximum power point for 1,500 hours under standard illumination conditions.
