Scientists in Brazil have found that photovoltaic modules may be a repository of specialised microbes in tropical regions. According to them, these micro-organisms may be used in sunscreens, pigments for processed foods, chemicals, textiles, pharmaceuticals, and cosmetics.

The US battery manufacturer entered the stationary storage business with a new product for residential customers. The lithium iron phosphate (LFP) battery is compatible with new or existing PV systems.

Norwegian scientists have developed a gallium arsenide (GaAs) nanowire solar cell that can be used as a top cell in a dual tandem cell with a bottom silicon cell. The device is claimed to be the most efficient single-junction GaAs nanowire solar cell grown on a silicon substrate so far.

Developed by Italian dry bottom ash handling system provider Magaldi Power, the system produces green thermal energy — steam or hot air — which can be used directly in industrial plants or for the generation of electricity using steam turbines. The system consists of a blower, a fluidisation air blowing system, a fluidisation air suction system, an air filter and fan, an air pre-heater, and an integrated thermal energy storage module. Silica sands are the system’s storage media.

Developed by Spanish scientists, the proposed system design is said to be able to achieve water temperatures above 70 degrees Celsius and to cover around 85% of the annual sanitary hot water consumption of a household with six people.

The continuous rise in solar panel prices may affect PV projects of up to 1 MW tendered by the Korea Energy Agency and the domestic solar module industry may not be able to provide the necessary production capacity to respond to the recent supply bottleneck.

A U.S. research team has sought to improve the way aluminium hydride is used for hydrogen storage. The material was nanoconfined in a framework that is claimed to be able to overcome the challenge represented by the thermodynamic limitation of hydrides in storing the clean fuel.

An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.

The new product has a power conversion efficiency of up to 19.3% and a weight of 11.2 kg. The module is produced with glass fibre reinforced plastic, which the manufacturer says reduces light reflection and opens up new assembly options.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.
