Chinese business Sinohydro has secured the contract for a 20 MW solar plant in Gardete, near the city of Bissau. The tender for the project was launched a year ago.

Researchers in Tunisia have proposed a method of determining the characteristic I-V profile of a partially shaded PV module, and to extrapolate it into a string profile.

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.

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.

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.

GlobalWafers, a Taiwanese wafer manufacturer, will add 150mm silicon carbide to its products, manufactured from bulk SiC crystals produced by GT Advanced Technologies, under a new multi-year agreement to “forge a new source of supply of silicon carbide wafers.”

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.

Netherlands trade body Holland Solar has asked the Ministry of Economic Affairs and Climate Policy for an extension of grid-connection deadlines for solar projects being built under the SDE+ incentive program for large scale renewables. The association also urged Dutch municipalities to keep processing permits.

A group of Scientists in India has demonstrated a 20% increase in a PV system’s energy yield through the use of mirror reflectors in the summer season. Though the technology is still far from being economically viable, the research shows that higher power yields can be reached without significantly affecting the module temperature.
