Inverted perovskite solar cell achieves 23.9% efficiency, high durability
A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.
Australia’s top 10 solar panel, inverter manufacturers
Sunwiz has revealed the leading rooftop solar and inverter manufacturers in Australia for 2022.
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%.
Manufacturer releases home backup solar battery
RoyPow introduced a new residential lithium-ferro-phosphate battery this week at Intersolar North America in Long Beach, California.
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.
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.
Global solar installations may hit 350.6 GW in 2023, says TrendForce
TrendForce says solar demand could grow by more than 53.4% this year due to lower module prices and delayed projects from 2021 and 2022 that are now going online. China will be the largest market this year with 148.9 GW, followed by the United States with 40.5 GW, India with 17.2 GW, Brazil with 14.2 GW, Germany with 11.8 GW, Spain with 11.4 GW, and Japan with 8 GW.
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.
Longi releases new alkaline electrolyzer
China’s Longi claims that its new ALK Hi1 electrolyzer can produce hydrogen with an energy content of 4.3 kWh per normal cubic meter. It says the levelized cost of hydrogen could be up to 2.2% lower than other electrolyzers on the market.
