Global polysilicon prices decline slightly
In a new weekly update for pv magazine, OPIS, a Dow Jones company, offers bite-sized analysis on solar PV module supply and price trends.
Adjusting oxygen distribution in Czochralski silicon crystal growth
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.
‘Polysilicon price will stay above $5.50/kg for at least a year,’ says analyst
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.
Solar module cooling tech based on waste neem oil
An international research team has placed a neem oil tank on the back of solar modules for cooling purposes. The proposed solution reportedly improves PV panel performance by up to 17.8%.
How much polysilicon is enough
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.
Chinese PV Industry Brief: CNMIA says polysilicon, wafer prices continue to fall
The China Nonferrous Metals Industry Association (CNMIA) says that prices for n-type rod silicon fell 3.3% on a weekly basis to between CNY 55,000 ($7,600) and CNY 60,000 per ton this week. It reports that wafer prices also fell between 3.5% and 15.6% during the same period.
