‘Massless’ battery breakthrough for lightweight EVs

A new type of carbon fibre and electrolyte matrix stunned scientists when they tested its properties. Their ‘structural’ battery could be used in electric vehicles and could even address the weight problems that bedevil devices planned for electric-powered flight.

Battery costs have fallen 97% since 1991, claim MIT researchers

Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.

Location-dependent performance model for bifacial installations

Bifacial PV modules and single-axis trackers go well together, but a global research team has now noted that a comprehensive location-dependent performance analysis still has yet to be done. Their findings could help to determine the right plant setups in different locations throughout the world.

Solid-state batteries in space

Japanese scientists are about to launch solid-state batteries into space.

Weekend read: Current developments

The incremental improvements achieved each year in solar are usually relatively small, and improvements to one component can easily be accommodated by the rest of the system. But every so often, a bigger change comes along, with implications that will ripple up and down the supply chain.

Sungrow launches second generation inverter in Australia

Chinese solar inverter giant Sungrow has taken the first step towards increasing its Australian market share in 2021 with the launch of its second generation three-phase residential inverters.

Tesla launches solar inverter

The EV manufacturer with big solar ambitions has finally leveraged its expertise in power electronics technology and launched a solar inverter.

The future of power electronics is distributed, aggregated and service oriented

IHS Markit released a white paper in which the analyst outfit shared some predictions for the power electronics market. First and foremost, inverters will become smarter, and after some power outages in key markets, these devices are gearing up to take on more grid stabilising tasks, which hitherto had been reserved for synchronous generators.

Adaptive solar shade system means horticulturalists can smell the roses

Researchers have modelled the effects of various PV module arrangements on a greenhouse used for rose growing in Iran’s Shiraz region. The team determined a ‘sweet spot’ where modules produced the most energy and provided optimal growth conditions for the crop.

A virtual-oscillator-based control strategy for microgrids

Researchers have modeled how the combination of a virtual oscillator control mechanism and a cascaded sliding mode control can help regulate voltage and frequency in a distributed-solar microgrid.
