Energy Vault to deploy 2 GWh of gravity storage in China
Energy Vault’s EVx storage system is comparable to pumped hydro, using grid-scale renewable energy when supply is abundant to drive motors and raise 30-ton blocks on a six-arm crane tower, rather than water, up to a height. When power needs to be discharged back to the grid, the blocks are lowered, harvesting the kinetic energy.
Perovskite solar module achieves 21.07% efficiency via nanosecond laser tech
Chinese researchers have used inverted perovskite cells with a p-i-n structure to build a perovskite solar module with a reduced heat-affected zone. The panel achieved a power conversion efficiency of 21.07% and a geometric fill factor of 95.5%.
