An oasis of PV
A new study shows solar may help reduce water pumping costs in a desert oasis of Mauritania significantly while reducing water losses. Researchers claim PV water pumping may also help prevent desertification.
New antenna for a better photon harvest
An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.
Solar and wind make coal unprofitable in Japan
Recent investments into 11 GW of new coal generation capacity may result in reduced operating cashflows of $71 billion. That will occur, according to a report from the Carbon Tracker Institute, because solar and wind will become cheaper than coal in Japan by 2025 at the latest, despite high renewable energy costs at present.
Solar delivers cheapest power in Jamaica
Neoen has completed the 51 MW Paradise Park solar plant in the Caribbean. The facility will generate electricity for the Jamaica Public Service Company Limited for US$85/MWh over 20 years.
Ireland allocates 110 MW in large scale storage auction
Originally intended to commission 140 MW of storage, the tender drew three winning projects: a 50 MW system and two 30 MW facilities. Eirgrid has estimated the total value of the contracts at around €6 million per year.
Deal signed for 40 MW solar park in DR Congo
The government of the Tshopo province has signed an agreement with Cat Projects Africa for the PV plant. The project will be connected to the grid operated by utility Société nationale d’électricité and is intended to improve power supply in provincial capital Kisangani.
Corsica hosts 5 MW/7.5 MWh solar plant with Tesla batteries
The project is in Giuncaggio, in the northeastern part of the French island, and was built with Tesla Powerpack batteries, a Nidec power management system and a new power management device from the project’s developer Corsica Sole.
Australia’s Horizon to replace overhead network with solar and batteries
A recent project milestone saw the disconnection of properties from overhead lines and will enable 64km of poles and wires to be replaced by off-grid solar-plus-battery solutions.
Chad gets financing for large scale solar-plus-storage project
An €18 million loan has been provided by the African Development Bank. The solar park, planned for capital N’Djamena, will be coupled to 4 MWh of storage.
New configuration gives perovskite cells 18% efficiency
Cesium lead black perovskites could be interesting for solar cell development if their crystals are observed in their less efficient but more stable beta phase. The efficiency shortfall can be solved by healing emerging cracks in the surface of the cell using a choline iodide solution, according to an international team of scientists.
