The cell, which looks externally like a device with a two-terminal architecture, was built with III-V semiconductor layers that were connected to the silicon sub-cell on the atomic level. The cell may be used in electrically powered aircraft and drones.

Module-level power electronics, most often in the form of power optimizers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?

Italian start-up Genius Watter has developed a solar desalination solution that is claimed to be particularly suitable for remote areas with no connection to grid electricity. The system is able to produce up to 1,000 cubic meters of potable water per day at an opex of €0.20 per cubic meter.

Solar installer Jake Warner has received surprising feedback from his customers after he chose to transition his company, Penrith Solar, exclusively to microinverters two months ago. “What I found is actually the opposite to what I expected,” Warner told pv magazine Australia.

The Cryosolar solution consists of a 20-foot or 40-foot container equipped with a plug-and-play PV system installed on the roof. It has 180 mm thick insulation and 10 to 35 cubic metres of storage with shelves.

Axter, a French waterproofing specialist, has revealed a new mounting process for the installation of rigid solar modules on several types of buildings, including concrete, metal, and wood surfaces.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

The panel was unveiled in October and is the most powerful product the company has brought to the market to date. The Chinese-Canadian manufacturer expects to reach, for this product, a 10 GW capacity by the end of the year.

The cell showed open-circuit voltage values of up to 732 mV. It was fabricated with a back junction (BJ) design with a full-area p-n-junction at the back surface.

Scientists in Russia introduce a promising new material for battery energy storage, the product of more than three years of research. Incorporating a nickel-salen polymer into the cathode, the group demonstrated a battery that can charge and discharge ten times faster than today’s lithium-ion batteries. And though the battery still lags in terms of overall capacity, the group is confident that its discovery will lead to big improvements for lithium batteries.
