Controlling water-to-water CO2 heat pump for optimal coefficient of performance
Scientists have designed a novel control approach for water-to-water heat pumps that use carbon dioxide. They relied on a virtual heat pump for their tests. The coefficient of performance (COE) improved by up to 14.6%.
Perovskite solar cell based on hole-selective interlayer achieves 26.39% efficiency
Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.
Samsung launches monobloc air-to-water heat pumps
The Korean manufacturer said its new products are now available in the North American market and are suitable for multi-unit homes, apartments, new-builds and retrofits. The systems work with new AI technology and reportedly perform better when connected to a PV system.

The Hydrogen Stream: PV-hydrogen polygeneration system for humid climates
Researchers have proposed an atmospheric polygeneration system for hot, humid climates that generates water, cooling, and hydrogen, while Inpex has started preparations for a blue hydrogen production project in Niigata, Japan.
Chinese PV Industry Brief: Xinyi Solar projects steep profit decline in 2024
Xinyi Solar says it expects a 70% to 80% profit decline for the year ending Dec. 31, 2024, due to low market prices, higher plant suspension costs, and inventory writedowns.
Scientists develop thermal model for floating solar with 15.45% efficiency
Scientists have developed a multi-physics thermal model for panels with a natural convection cooling loop and tested it against experimental data. They have also experimented with varying the coolant channel thickness and different coolants. The highest measured electrical efficiency reached 15.45%.
