Solar PV

Researchers in Germany and Belgium have discovered ‘zero point vibrations’ are responsible for performance limitations in organic solar cells. New strategies to minimize such vibration-induced voltage losses in organic PV should be investigated, say the scientists.

Tesla’s Nevada operation is still open for business, though. The EV and battery maker has assured the market its cash position is strong enough to weather an “extended period of uncertainty”.

The Renewable Energy Project Development Office has prequalified 49 developers for the tender. Four large-scale solar projects will be built via the procurement exercise.

Gujarat Urja Vikas Nigam Ltd. has opened bids to develop 700 MW of solar capacity in India.

U.S. researchers have conducted detailed balance calculations to show the ultimate potential of underwater solar cells. According to their findings, the devices could theoretically produce useful power at up to 65% efficiency in clear waters. However, this would only be possible by using wide-band-gap semiconductors, which have not been considered for solar cells used for land-based applications because their band gaps are too large.

Norwegian energy producer Equinor and Italian oil contractor Saipem have joined forces to build floating PV projects for near-coastal applications. The two companies plan to use a technology developed by Moss Maritime, a unit of Saipem.

According to SolarPower Europe, local agriculture and solar energy could become the engines of a sustainable European economy. The trade body has created a task force, led by French independent power producer Amarenco, that aims to place agrivoltaics at the top of the European agricultural policy agenda, while also establishing global standards for the segment.

pv magazine has spoken to Germany’s largest solar project developers about how construction has ground to a halt on many PV projects in Europe since the beginning of the coronavirus pandemic. Politicians need to extend implementation deadlines for PV projects that are being built under tender schemes, but deadlines are not the only challenge that companies currently face.

The country’s energy regulator published two papers this week to solicit public feedback on plans that Mineral Resources and Energy Minister Gwede Mantashe recently submitted for review. The first document relates to the tech-neutral procurement of 2 GW of short-term risk-mitigation capacity, which could see solar emerge as a winner due to its quick deployment times. The second paper is linked to the nation’s Integrated Resource Plan 2019, which aims for up to 6 GW of new large-scale solar by 2030, as well as an additional 6 GW of distributed-generation capacity.

A study led by Bern University of Applied Sciences is moving into the demonstration phase, with projects in Germany, Switzerland, and Belgium. With partners from all over Europe, the Swiss researchers are developing models for how solar modules and batteries from electric cars can still be used in a sustainable way after their lifecycle has ended.
