Scientists in China have used a fused-thiophene spacer to build a two-dimensional perovskite solar cell. It has an open-circuit voltage of 1.03 V, a short circuit current of 22.38 mA cm2, and a fill factor of 81.64%.

MIT researchers have created a semisolid flow battery that might be able to outperform lithium-ion and vanadium redox flow batteries. It features a new electrode made of dispersed manganese dioxide particles shot through with an electrically conductive additive, carbon black.

The solar array will cover around 30% of the electricity needs of a Leroy Merlin hypermarket in Volzhsky, in Russia’s Volgograd region.

Taiwanese solar manufacturer Motech is expanding its TOPCon module capacity to meet rising demand. Its flagship product is a TOPCon 360 W panel with a power conversion efficiency of 21.1%.

A Dutch consortium is testing a 20 kW pilot floating PV installation for offshore applications with CIGS solar modules developed by Swedish manufacturer Midsummer. The panels consist of 144 solar cells and measure 4 m X 1 m, with up to 485 W of capacity.

Varta’s Element Backup battery is available in three versions with storage capacities of 6.5 kWh, 13.0 kWh, and 19.5 kWh.

A 3.3 MW rooftop PV array and 480 kW of linear generators are currently being used to cover 100% of the electricity needs of a logistics facility in California. The hybrid energy system is relying on a linear generator technology provided by U.S. specialist Mainspring Energy that converts mechanical energy into electrical energy.

The solar-powered electronic shelf labels are intended for use in retail stores. Users are enabled to change prices centrally and synchronously across all retail stores within a chain.

The PVonceal module skirt protects all of a module’s electrical components while maintaining sleek aesthetics for the lifetime of the installation.

A French research group has compared the performance ratio of 100 PV systems relying on micro-inverters with that of 100 installations relying on string/central inverters. It found the performance ratio is around 79% for both system typologies and that arrays with micro-inverters are more sensitive to environmental factors.
