A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Also known as "solar chip" or "photovoltaic cell", it can output voltage instantly and generate current in the case of a loop as long as it is illuminated by a certain illumination condition. In physics, it is called solar photovoltaic (Photovoltaic, abbreviated as PV), referred to as photovoltaic.

Recently, the world's largest 100MW/400MWh all-vanadium redox flow battery energy storage power station, the world's largest 100MW/400MWh class all-vanadium redox flow battery energy storage power station, has completed the main project construction. , and enter the single module debugging stage.

According to reports, CellCube, a supplier of vanadium redox flow batteries (VRFB), said a few days ago that it has reached a five-year agreement with American Vanadium to supply 3 million liters of electrolyte per year; in addition, the global safety certification body American Insurance Commercial Laboratories (UL) will conduct tests on Australian zinc-bromine flow battery manufacturer Redflow's zinc-bromine flow battery.

Inspired by dandelion's use of wind to disperse seeds, a US research team has developed a portable device with tiny sensors that can be blown away by the wind as it tumbles toward the ground. Once on the ground, the unit can hold at least four sensors, use solar panels to power its load electronics, and share sensor data from up to 60 meters away. The research results were published in the journal Nature on the 16th.

According to foreign media reports, Eskom, a South African power grid operator, recently stated that it plans to develop and deploy multiple battery energy storage systems with a total scale of 199MW/832MWh. The company is also considering another energy storage project that could be twice as large.

According to the latest news from the Australian Ministry of Industry on March 18, the proportion of renewable energy generation in the national electricity market in 2021 will account for nearly one-third (32.2%), and this proportion will further jump to 35.8% in the fourth quarter.

​Electric bicycles and new energy vehicles have become prominent hidden dangers affecting the safety of the public, and new energy and new business formats continue to generate new risks of fire.

​Energy consultancy EnAppSys has claimed that the award of contracts to battery storage systems above 1GW in the UK's recent new round of capacity market auctions is interesting news.
