The device achieved the highest efficiency and fill factor ever reported for an all-polymer solar cell based on polymerized small molecular acceptors. The cell was built with a top donor material known as PBDB-T and an electron acceptor made of the polymer PYT.

The US manufacturer said the device has an efficiency of 99.0% and a California Energy Commission (CEC) efficiency of 98.5%. It has a size of 750x1125x390 mm and weighs in at 131.5 kg.

The cell may be potentially used as a top subcell in tandem crystalline silicon-based devices. It was built with CdSe thin film with a direct bandgap of 1.72 eV.

A Japanese group has developed a storage system with potential applications in residential storage, electric vehicles, drones and Internet-of-Things devices.

Scientists in the United States have proposed to use a thermochemical energy storage (TCES) technique that stores energy in chemical bonds to recover the heat produced during air compression operations. According to them, this innovation may increase the round-trip efficiency of compressed air energy storage to 60%.

The campus of the Delft University of Technology (TU Delft) in the Netherlands is currently hosting a retrofitted existing building provided with heating by an H₂ heating boiler in the attic. The boiler is linked to an underground hydrogen system.

The U.S.-based non-profit organization is supporting the United States Agency for International Development (USAID) in the development of the three mini grids. The incentives for the projects will be provided in the form of grants.

Developed by scientists in China, the cell achieved an open-circuit voltage of 1.192V, and a fill factor of 80.67%. Its perovskite capping layer was treated with a special ionic liquid that had a positive influence on both the device’s efficiency and stability.

South Korea’s cumulative installed PV capacity hit 22 GW at the end of 2021, according to provisional figures from the Korea Energy Agency.

Recent research from Thailand has shown that solar-plus-storage on floating platforms could be the cheapest option to power energy-intensive aeration systems in aquaculture projects. The battery accounts for around 54% of the capital costs, which is why system sizing would be key for economic viability.
