Chinese PV Industry Brief: CNMIA reports increase in polysilicon prices
The China Nonferrous Metals Industry Association (CNMIA) says that polysilicon prices rose this week, while TCL Zhonghuan raised wafer prices for the second time in 10 days.
Biwatt unveils new residential sodium-ion batteries
Biwatt Power, a Chinese manufacturer, has developed new residential sodium-ion batteries with an efficiency rate of 97% and a projected lifespan of more than 3,000 cycles.
The Hydrogen Stream: Scientists see iridium as obstacle to hydrogen aviation
A German research team says that demand for iridium, lanthanum and nickel could weigh on the growth of the global hydrogen-powered aviation market.
Dual source heat pump with high seasonal performance factors, near-zero defrosting costs
A UK-Chinese research group designed a dual-source heat pump (DSHP) that recovers the waste heat from the exhaust air along with absorbing the heat from the outdoor air. A prototype installed on the roof of a building in the UK showed remarkable results in terms of coefficient of performance and annual heating bill savings.
Chinese PV Industry Brief: Daqo, Longi note earnings impact of polysilicon prices
Daqo and Longi report that lower polysilicon prices have affected their earnings. Aiko Solar, meanwhile, has announced a 120% year-on-year increase in its net results for the first half, with shipments reaching 18.7 GW.
PVC knife-scratch coated fabric to increase albedo, energy yield in bifacial PV
China-based Halead is offering a reflective material for ground-mounted bifacial PV projects, which it claims can increase the annual power production of a solar plant by over 9%. Germany’s TÜV SÜD certified the performance of the solution.
Energy Vault completes 25 MW/100 MWh gravity-based storage facility in China
Energy Vault has started commissioning a 25 MW/100 MWh energy storage facility adjacent to a wind power facility near Shanghai.
New technique to recover lead in end-of-life solar panels
A research group in the United States has developed a process to recover lead in its metallic form so that it can be reused in the PV industry. The process relies on a leaching solution based on a combination of acetic acid (CH3COOH) and hydrogen peroxide (H2O2), which the researchers said leaches the lead ‘in a matter of minutes.’
The Hydrogen Stream: Chinese scientists exploring new catalysts for hydrogen
Shanghai University scientists have started researching molybdenum-doped nickel-cobalt phosphide catalysts for hydrogen production, and Indian scientists have devised a method to produce hydrogen from methanol.
Chinese PV Industry Brief: GCL-Si opens 20 GW solar cell factory
GCL-Si says it has commissioned a new 20 GW solar cell factory that will supply n-type TOPCon cells to its module facilities in Hefei, Anhui province, and Funing, Jiangsu province.
