Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that are at least two years old. The new product is claimed to increase power yield by up to 7% and to have a payback time of 2.5 to four years depending on the dust level of the site.

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.

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.

The planned storage capacity will come from 20 projects selected by Italian grid operator Terna through the latest capacity market auction. Half of them will be located on the island of Sardinia.

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.

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.

Two industry experts have provided analyses of the current polysilicon price scenario in a chat with pv magazine and both agreed that polysilicon demand is still growing faster than supply. The price may decrease starting from the second quarter and reach more reasonable levels by the end of the year.

The Japanese government is proposing 20-year FITs lower than $0.010/kWh for rooftop PV and a ceiling price of $0.087/kWh for solar energy auctions. These incentive levels will likely be insufficient to stimulate demand given rising solar project costs.
