Scientists from China developed a controllable moisture treatment for perovskite films that is reportedly able to promote the mass transportation of organic salts. The films were used to build a 0.2 cm2 perovskite solar cell that was able to retain 80% of its initial efficiency after 1200 h.

The aerator consists of a 200 W solar panel, an aerator frame, an eight-leaf windmill for paddling water and restoring oxygen levels, a DC motor working as a driving wheel, a buoy as a component lifter, and a box panel as a protective tool that uses the electricity network.

Researchers in Saudi Arabia claim to have reduced cell-to-module losses in tandem perovskite silicon photovoltaic devices through an optical redesign of the module through refractive-index engineering. They built a monolithic perovskite-silicon tandem mini-module with a power conversion efficiency of 26.2%.

The new module has a power conversion efficiency of up to 21.5% and a temperature coefficient of -0.35% per C.

SEV, the utility for the Faroe Islands, has secured funds from Nordic Investment Bank to build a pumped hydro storage facility on the island of Streymoy. The Mýruverkið II project, valued at DKK 1.3 billion ($174 million), is set to go online in the 2027-28 period.

An international group of researchers has developed a cubical luminescent solar concentrator (LSC) PV device that can be assembled in mosaic configurations for applications in urban environments. The best-performing device achieved a power conversion efficiency of 11.6%.

A Swedish-Italian research group has applied state-of-the-art models for global horizontal irradiance decomposition to assess photosynthetically active radiation in agrivoltaic projects – an important variable to properly predict crop yield.

Dutch manufacturer MG Energy Systems is offering a new storage system in two versions, with capacities of 5.8 kWh and 7.2 kWh and nominal capacities of 230 Ah and 280 Ah.

Australian researchers have developed a way to use rooftop PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.

Bhutan aims to facilitate the construction of its first PV project through a new tender.
