Pumped hydro energy storage can be readily scaled to any required storage capacity at a known and affordable cost.

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.

Sunwiz has revealed the leading rooftop solar and inverter manufacturers in Australia for 2022.

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%.

RoyPow introduced a new residential lithium-ferro-phosphate battery this week at Intersolar North America in Long Beach, California.

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’s Ministry of Industry and Information Technology (MIIT) says Chinese manufacturers produced 357 GW of wafers and 318 GW of solar cells in 2022.

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.

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.

Chinese scientists have simulated a new photovoltaic-thermoelectric technology, based on radiative cooling and III-V solar cells, to generate electricity at night.
