New solar battery efficiently stores energy in liquid form

Researchers from the University of Wisconsin-Madison (USA) have developed a new dual energy system that generates energy and stores it for future needs. To do this, they combined two known technologies – solar panels and liquid battery in a single complex. Also, each of components has been implemented on new materials with improved properties.

New solar panels made of plates of silicon with the usual additives extremely promising material perovskite. They absorb waves of different lengths, allowing you to capture much more useful radiation. In the liquid battery is time-tested, but too aggressive acidic electrolytes used organic compounds in saline solution. The formulas are secret, but the new electrolyte carefully call a perfect composition for batteries of this type.

The resulting system has a high stability – she has a constant efficiency of 20 % in all modes. You can set the device at the sun directly and to take from him the energy, and it can accumulate in the liquid electrolyte of the battery to the end of the day to get the same 20 %. This is very useful for creating stand-alone systems in remote regions where the Sun is the only source of energy.

Right next to us lives a young star aged only 33 years

February 24, 1987, sudden cosmic explosion shook the astronomical community. This event, called “Supernova 1987A” (SN 1987A) was the most closest to the Earth supernova observed since the invention of the telescope. SN 1987A exploded in the Large Magellanic Cloud, located about 170 000 light years from Earth. It was so bright that observers were […]

Breakthrough: scientists were able to record the info in synthetic molecules

In theory, storage and transmission of information any material, medium or thing, in which you can implement the specified sequence of parameters. This battle signal the drums, and Morse code and binary code in the chip. And recently, scientists have created a synthetic molecule, new substance, in the structure of which the recorded information. One […]
