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.

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.

The Central Electricity Authority, CEEW’s Centre for Energy Finance, and Shakti Sustainable Energy Foundation have launched an online dashboard that captures daily generation data at the state, regional and national levels for the aggregate 93 GW of installed RE capacity in India. It also captures this data at a plant level for a subset of projects.

The US cadmium telluride thin-film module maker said its Series 6 CuRe panels are able to retain 92% of its performance at the end of the 30-year warranty. The improved stability of the product was achieved by eliminating copper and placing Group V elements such as antimony or arsenic onto the tellurium crystal sites.

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.

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.

The innovators will be required to showcase their technologies in actual field conditions. The shortlisted ones will be empanelled and allocated sites for installing solar pumps under the Pradhan Mantri Kisan Urja Suraksha evem Utthan Mahabhiyan (PM KUSUM) Scheme.

Scientists have set a new efficiency record for a single-junction perovskite solar cell at 25.6%. The cell additionally showed operational stability for 450 hours, and intense electroluminescence with external quantum efficiencies of more than 10%.
