According to new research, metal chalcogenide perovskites can be used as a thermoelectric material than can convert thermal energy from the sun to usable electric power. These materials, which can also be used to develop perovskite PV cells, are known for their high thermal and aqueous stability, along with their nontoxic elemental composition.

Mali is set to host one of the world’s largest off grid solar+storage projects, as a 30 MW solar plant will soon be coupled with a 17MW/15MWh storage facility to power the Fekola gold mine. Finland’s Wärtsilä will supply the battery.

Spanish researchers are proposing a customer-driven method described as an intuitive tool for investors and engineers to assess how self-consumption from solar generation can be profitable. The method is said to take into account economic parameters such as taxes, depreciation and the cost of financing.

State-owned Elektrani na Severna Makedonija will begin construction on a 10 MW solar plant at its redundant coal plant in Oslomej after signing the engineering, procurement and construction deal with a Turkish contractor. The utility is planning to tender a 10 MW extension of the plant and two more 50 MW solar facilities.

An Indian research team has analyzed around 300 scientific studies about PV panel waste containing carcinogenic metals. The researchers said solar module recycling is not economically profitable and policy support is necessary to avoid panels being dumped in landfill.

The Spanish government has selected 55 solar installations in the procurement exercise. About 256 MW of the projects it awarded will be built on Mallorca, while Menorca, Ibiza and Formentera will host 61 MW, 6 MW and 2 MW of new capacity, respectively.

Scientists have observed that the efficiency of an organic PV device decreases by around 50% when it is exposed to 100-h light irradiation. They attributed this loss to increased resistance of the organic semiconductor layer.

The Taiwanese PV manufacturer said the project will be the largest solar installation on the island. Construction is scheduled to being near the city of Tainan in the second half of 2020.

A group of scientists is proposing a new metric – the value of efficiency – to calculate the maximum allowable cost to increase a cell’s efficiency and improve the levelized cost of electricity (LCOE). The researchers expect that more regional diversification may be seen at the global level in the years to come, with the proposed metric offering higher values in North America, Central and Northern Europe, Japan, Australia, and New Zealand.

The new concept of the Desertec initiative, which was presented at the Energy Transition in the Arab World Conference in Berlin last week, is still based on the idea that large-scale solar and wind energy can be developed and used in the deserts of the Middle East and North Africa. It also includes, however, that hydrogen and other synthetic emission-free energy carriers can also be developed throughout the region with clean energy and then exported to world markets.
