EV sales are set to be 1.7 million off because of the economic fallout of the Covid-19 crisis, however analyst BloombergNEF predicts that will be less of a hit than the anticipated fall in sales of conventional cars, increasing the penetration of electric models into the overall market.

Researchers in Japan have demonstrated a new concept for a ‘heat-recovery’ solar cell, which they claim has the potential to exceed the theoretical limit for cell efficiency. They say, however, that a suitable material for the energy filtering layers is yet to be identified. The cell is equipped with a 100-micron thick silicon absorber, two electrodes and carrier-energy filtering layers placed between the absorber and electrodes.

Japan’s Kaneka and Taisei have designed their T-Green Multi Solar system to be integrated into walls and window surfaces. The system is available in two different versions – a solid type in which PV laminates are turned into vertical exterior panels or walls, and a variant that achieves transparency through striped solar cells that are integrated into window glass.

As a focus of research at leading institutes the world over, new developments in the perovskite field come thick and fast almost every week. From x-ray observations on a nanoscale to financing and plans for mass production, pv magazine is bringing together some of the most exciting developments of recent weeks.

Up to 150 GW of PV and wind projects could be postponed or canceled throughout the Asia-Pacific region by 2024 if the coronavirus-triggered recession continues beyond the current year, according to new research by Wood Mackenzie.

Solar project owners responded to an appeal to donate a portion of their solar incentive payments to the public health authorities as another multinational body emphasized the importance of coronavirus fiscal stimulus packages having environmentally-friendly conditions attached.

The losers in a world which no longer runs on fossil fuels are obvious but the dividend from shrugging off hydrocarbon dependency will be spread around most of the world so it is the nations which are winning the cleantech manufacturing and intellectual property race which appear best positioned for the future.

The electronics brand said the project will be its largest engineering, procurement and construction order for a solar plant. Facilities on such a scale are rare in Japan because of land constraints.

The ‘best conversion performance in the world in a dark room’ is how the developers of a new organic PV device have described it. Such cells could be used as a wireless source of energy for internet of things applications or in gadgets such as temperature-humidity and motion sensors.

Toshiba has finalized construction of a 10 MW hydrogen plant in Fukushima prefecture which draws power from 20 MW of solar generation capacity as well as the grid.
