Swimming electrons in perovskite nanocrystals
Research from Canada has revealed liquid-like lineshape dynamics in cesium-lead iodide perovskite nanocrystals. The findings could be used to produce cheaper and more efficient perovskite cells, researchers claim.
Straining to fix perovskite cells
A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.
Google’s reverse auctions net 1.2 GW of renewables in 60 minutes
Google pre-qualified bidders and used reverse auctions to obtain the lowest price for renewable energy. Reverse auctions for corporate purchases could potentially benefit solar developers, if their transparency and simplicity can influence more corporations to procure green power.
Singyes shareholders approve China bail-out
The margin of support for the proposed $198 million takeover by a Beijing entity came as no surprise and the deal now hinges on the holders of $430 million of defaulted debts supporting a delayed settlement of their claims. First up, though, is a date with a winding-up petition on Monday.
DTEK inaugurates 240 MW solar plant in Ukraine
The energy company wrapped up construction of the site in eight months. In March, DTEK commissioned a 200 MW site which was also installed in record time.
Germany added 2.9 GW of solar in nine months
In September, PV systems with a total generation capacity of 287 MW were registered in the country. The feed-in tariff has fallen again for this quarter as a result of the new capacity additions.
Solar electricity can retail for $0.027-0.036/KWh as renewables close in on global grid parity
The latest figures released by BloombergNEF show new solar and onshore wind power plants have reached parity with average wholesale prices in California, China and parts of Europe. The technologies are winning the race to be the cheapest sources of new generation for two-thirds of the world’s population.
Russian Far East sees 75 MW of large scale solar come online
Five PV power plants, each with a generation capacity of 15 MW, were grid-connected in the Russian Republic of Buryatia and the Zabaikalsky Territory. The projects were built under a program which offers generators capacity payments and the ability to trade on the wholesale energy market.
Another 5 GW of module capacity for the Longi juggernaut
The mono giant has announced the latest aspect of a strategy to massively increase production capacity which is currently set to cost around $3.32 billion. Longi last week issued $710 million of new convertible bonds for investors.
Can Nam Ngum solar replace Mekong hydro in Laos?
The Lancang-Mekong River is being decimated by hundreds of tributary and mainstream hydroelectric projects from the Tibetan Plateau in China to Lower Sesan in Cambodia. On the Mekong, the Laos Government has constructed the majority of these projects and it is planning even more. But why does it only focus on hydroelectric power plants (HPP’s)? What about other renewable energy sources? Can Nam Ngum solar replace Mekong hydro?
