Uzbek utility Uzbekenergo had received 23 offers for the 100 MW tendered solar plant. Two more solar tenders, with capacities of 400 MW and 500 MW, respectively, will be launched in the near future.

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.

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%.

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.

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.

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.

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.

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.

An accelerated transition to renewables could go either way, regarding the United States’ unique geopolitical strength. According to Indra Overland – head of the Center for Energy Research at the Norwegian Institute for International Affairs – the U.S. could surrender a major advantage if it abandons fossil fuel. The nation could, however, remain dominant in the global energy sector if it continues to lead on innovation and clean energy tech-related intellectual property.

According to figures from Italian renewables body ANIE Rinnovabili, 18,036 storage systems coupled to clean energy power generation have been installed in the country. Most of the batteries are in Lombardy, whose administration offers rebates.
