The 19.2%-efficient perovskite cells used in the module rely on an electron layer based on tin oxide that was deposited via chemical bath deposition. This technique, according to the device’s creators, has made it possible to have a relatively small drop in efficiency from small cells to the 40cm² module.

WiTricity has unveiled plans to develop wireless charging stations for select electric vehicle models.

Elsewhere, Chinese researchers have synthesized ultrafine Pd100-xCux nanodot-modified TiO2 photocatalysts that display optimized energy barrier for interfacial hydrogen desertion, which reportedly exhibits excellent H2-evolution activity and stability, and Mitsubishi Heavy Industries has presented its plans to establish the Takasago Hydrogen Park, calling it the world’s first center for validation of hydrogen-related technologies, from hydrogen production to power generation.

The tandem cell was fabricated by German scientists through a process flow that is compatible with industrial, mainstream PERC technologies. According to its creators, the device has the potential to exceed efficiencies of over 29% with adjustments in the perovskite thickness and bandgap.

Developed by Germany’s Fraunhofer ISE, the cell is manufactured with metallization based on a plating process. The device was built with galvanic nickel/copper/silver contacts instead of common silver contacts.

Operated by UK start-up Power Roll, the pilot factory will reach a capacity of 30 MW by year end. The manufacturer uses low-cost roll-to-roll manufacturing processes and patented microgroove patterns to produce flexible solar panels intended for applications on warehouses and agricultural sheds whose roofs are not strong enough for conventional arrays as well as in vehicle-integrated photovoltaics.

International express shipper DHL is topping its trucks with solar to limit fuel usage by powering lift gates and ancillary devices.

A recent report from HTW Berlin and Verbraucherzentrale NRW reveals that, between 2020 and 2021 alone, around 128.000 new plug-in solar arrays, totaling 51MW of generation capacity, were installed in Germany.

Developed by a French start-up, the robotic mower can be used in a 50-unit herd across a property of around 50 hectares and a radius of 20 km. It is powered by polycrystalline cells and equipped with battery storage. The system can operate with a maximum slope of 15% and reach a speed of 300m/h.

Scientists in Australia have developed an optimization framework for building-integrated photovoltaics that allows the selection of design variables according to user preferences. Their model considers PV-related features such as tilt angle, window-to-wall ratio (WWR), PV placement, and PV product type, as well as objective functions and constraints such as the net present value and the payback period.
