Longi raises wafer prices as polysilicon hits $34.98/kg
The China Nonferrous Metals Industry Association (CNMIA) said that prices for monocrystalline silicon ranged from CNY 222 ($32.30)/kg to CNY 248/kg last week, up 31.37% from the middle of January. Longi, meanwhile, has raised its wafer prices by more than 15%.
US scientists improve photoresponsivity in solar perovskite by 250%
Researchers led by the University of Rochester claim to have increased the photoresponsivity of a lead-halide perovskite for solar cell applications by 250%. They created a perovskite film with a plasmonic substrate made of hyperbolic metamaterial and characterized it with transition dipole orientation.
Gautam Solar unveils ALMM-approved 10BB bifacial panels
The ten-busbar panels are available with peak power outputs ranging from 520 W to 550 W with front-side conversion efficiency between 20.11% and 21.27%.
China produced 288.7 GW of modules, 827,000 MT of polysilicon in 2022
China’s Ministry of Industry and Information Technology (MIIT) says Chinese manufacturers produced 357 GW of wafers and 318 GW of solar cells in 2022.
Replacing MPPT with direct PV-battery coupling
Researchers in Germany have assessed direct coupling and integration between PV and batteries at the scale of a single PV module. They say their solution could be cheaper and provide superior performance than maximum power point tracking (MPPT) in optimizing PV system performance.
Photovoltaic-thermoelectric tech with potential efficiency of 65%
Chinese scientists have simulated a new photovoltaic-thermoelectric technology, based on radiative cooling and III-V solar cells, to generate electricity at night.
