Lithium-sulfur battery with shorter charging time, longer lifespan
Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.
Poland deployed 1.3 GW of solar in H1
In the second quarter of the year, more than 763 MW of solar was deployed in the eastern European country.
Ligand-free perovskite quantum dot solar cell with 9.3% efficiency
The quantum dots used for the device are based on methylammonium lead iodide and are synthesized within a porous silica (SiO2) matrix. Compared to its bulk counterparts, the ligand-free solar cell exhibited a more stable performance.
German manufacturer unveils 10-busbar, half-cell PV modules
Bauer Solartechnik GmbH has released its new 400 W and 405 W BS-M10 PV panel series for rooftop projects.
Indian state tenders 224 MW of grid-connected PV
Gujarat State Electricity Corporation Limited. has opened an EPC tender for 224 MW of grid-connected solar capacity in the Indian state of Gujarat. The projects will range in size from 10 MW to 55 MW, with bidding set to close on Sept. 8.
Australian science agency looks to space to test next-gen PV cell tech
The Commonwealth Scientific and Industrial Research Organisation is pushing the limits of flexible solar PV cells by partnering with Australian startup Space Machines Company to test the technology in space.
France launches multiple solar tenders
On August 5, the French energy regulator published the bidding rules for a new series of solar and renewable energy tenders. The application deadline is between October and December 2021.
Indium supply not an issue for CIGS industry
Scientists Ayodhya Tiwari and Daniel Lincot recently spoke to pv magazine about the future of copper indium gallium selenide solar tech, which could play a key role in providing flexible, lightweight products in the building-integrated PV segment.
Recovering waste heat from solar cells via a thermoelectric generator
Scientists in Italy have created a hybrid thermoelectric photovoltaic (HTEPV) system based on a thermoelectric generator and a wide-gap perovskite solar cell. The device is able to recover waste heat from the PV unit and produce additional power. According to its creators, this configuration needs large gap cells as these are less sensitive to temperature in terms of efficiency
Change in ownership for 153 MW PV project in Romania
The 153 MW Ratesti PV project was acquired by Israel-based independent power producer Nofar Energy. The facility will be located in the Arges county, in southern Romania.
