Researchers in Malaysia have simulated a mixed cation perovskite solar cell integrating tin and germanium in the absorber. By modulating the perovksite layer thickness, they were able to achieve an efficiency ranging from 24.25 % to 31.49 %

The new heat pumps use R-454B as a refrigerant and are specifically designed to be matched with Johnson Controls’ residential gas furnaces. Their size ranges from 1.5 tons to 5 tons and their coefficient of performance (COP) spans between 3.24 and 3.40, according to the manufacturer.

Beijian Energy says it will build a new factory to make heterojunction (HJT) solar cells and panels. The facility in Liaoning province will produce 4 GW of cells and 3 GW of PV modules.

An international team has demonstrated a perovskite solar cell relying on inorganic calcium nitrogen iodide (Ca3NI3) perovskite and has found this absorber material offers advantages such as tunable bandgap and resistance to heat. The device achieved a fill factor of 81.68%.

Researchers in China have compared the performance of catenary and taut mooring systems for offshore floating PV systems. They found that the taut system offers a higher degree of reliability in shallow water environments with severe tidal variations.

Utility Eskom is seeking proposals to build a 75 MW solar plant at the Lethabo Power Station in South Africa’s Free State province.

The Chinese manufacturer said its new frameless module can be installed on a balcony through nylon cable ties, without the need for any mounting structure. The new product features a power output of 200 W and a power conversion efficiency of 16.2%.

Researchers in Taiwan have discovered that in polysilicon production the crucible angular speed affects the oxygen concentration near the crucible wall, which in turn affects the wafers’ mechanical and electrical properties. They simulated a Czochralski process for an ingot with a diameter of 200 mm diameter and a length of 700 mm.

Andries Wantenaar, solar analyst at Rethink Technology Research, tells pv magazine that high overcapacity levels in the polysilicon industry are exerting enormous pressure on prices for the entire supply chain. He says China hit 2.4 million tons of polysilicon production capacity at the end of 2023, and notes that the nation will end 2024 with 4 million tons of capacity if all announced production plans are realized.

TU Delft researchers have proposed a new approach for solar cell manufacturing that implies gauging wafer thickness depending on the regions where the cells and modules will be deployed. They also suggested to adopt test conditions that are representative of the outdoor working condition of solar cells in an alternative to standard testing conditions.
