Singlet fission may raise theoretical efficiency of solar cells to 44%
According to a U.S. research team, new nanomaterials relying on dyes based on diketopyrrolopyrrole and rylene can generate a singlet fission reaction that extends the life of harvestable electronic charges.
Thai utility EGAT plans 69 MW of floating PV projects
Floating plants with capacities of 45 MW and 24 MW have been announced by Thailand’s largest power provider. They may be the first of nine projects at dams operated by the utility.
Solliance claims 21.5% efficiency for perovskite CIGS cell
The European solar research organization, Solliance announced it has achieved a 21.5% efficiency for a flexible copper indium gallium selenide (CIGS) tandem solar cell based on perovskite.
‘China’s most efficient’: Hanergy hits 24.34% efficiency on HJT cell
Chinese PV manufacturer Hanergy Thin Film Power Group today announced it has achieved 24.23% cell efficiency using its silicon heterojunction technology. The efficiency has been confirmed by Japan’s Electrical Safety & Environment Technology Laboratories.
India’s 10 GW mega tender has now been trimmed to 3 GW
A week after rejecting the sole bid received – from Azure Power – for its manufacturing-linked 10 GW solar procurement, the government has trimmed the size of the ill-fated exercise by more than two-thirds.
Netherlands PV market expanded by 46% in 2018
Dutch New Energy’s report reveals residential PV is no longer the largest growth driver – commercial and industrial and large-scale solar are now taking the lead. With newly installed PV capacity of 1.3 GW, the country saw its largest increase in new installations last year.
German researchers increase open circuit voltage of perovskite solar cells to 1.26 volts
The voltage is key to improving efficiency, the scientists say. It indicates how much energy is lost within the cell through ‘recombination processes’.
French researchers produce 348 W half-cell HJT module
Scientists at France’s Alternative Energies and Atomic Energy Commission, working with Swiss equipment supplier Meyer Burger, have hit 23.9% efficiency in large-scale production of heterojunction cells. The team also combined HJT cells with other technologies to produce a module with a 348 W power rating.
Atlas switches on 67.1 MW solar plant in eastern Brazil
The São Pedro solar complex is in Bom Jesus da Lapa, Bahia state. The plant, awarded a 20-year PPA in Brazil’s 2015 renewable energy auction, was installed with Jinko and Canadian Solar modules. The latter makes modules in São Paulo.
The weekend read: Reflections on a soiled module
Having quickly proven their performance-boosting potential and durability, anti-reflective coatings are now found on the majority of modules rolling off the world’s production lines. Today, coating suppliers are looking to tackle losses from soiling as well as reflection, and working to keep up with cost reductions and extended lifetime expectations at module level. Older modules, installed without a coating, could also be set to benefit from the latest innovations.
